Global Disasters Uprooted Tens of Millions in 2012

Posted by feww on May 14, 2013

Floods, storms and earthquakes forced 32.4 million people to flee their homes

At least 32.4 million people were forced to flee their homes in 2012 by floods, storms and earthquakes,  according to a new report released by the Internal Displacement Monitoring Center (IDMC).

8 Mega Disasters, events causing more than one million
people to lose their homes, accounted for 68% of all global
displacement in 2012. —IDMC

  • Asia and west and central Africa were the worst affected regions, however, at least 1.3 million were displaced in rich countries, with the USA particularly affected, said the report.
  • “98% of all displacement in 2012 was related to climate- and weather-related events, with flood disasters in India and Nigeria accounting for 41% of global displacement in 2012. In India, monsoon floods displaced 6.9 million, and in Nigeria 6.1 million people were newly displaced. While over the past five years 81% of global displacement has occurred in Asia, in 2012 Africa had a record high for the region of 8.2 million people newly displaced, over four times more than in any of the previous four years.”

  • United States was among the top ten countries with the highest levels of new displacement, with nearly one million people being forced to abandon their homes in 2012.
  • Displacement in poorer countries accounted for 98% of the global five year total, the report said.

In 2012, an estimated 32.4 million people in 82 countries
were newly displaced by disasters; 144 million over five years

  • “In countries already facing the effects of conflict and food insecurity such as in Nigeria, Pakistan, and South Sudan, we observe a common theme” says Clare Spurrell, Chief Spokesperson for IDMC. “Here, vulnerability to disaster triggered by floods is frequently further compounded by hunger, poverty and violence; resulting in a ‘perfect storm’ of risk factors that lead to displacement.″

The vast majority of this displacement (98 per cent in 2012;
83 per cent over five years) was triggered by climate- and
 weather-related hazards such as floods, storms and wildfires.
2012 had the lowest level of dis-placement due to geophysical 
disasters for five years; around 680,000 people were displaced
by earthquake and volcanic eruption disasters.

‘Red’ Alert at Copahue Volcano

Posted by feww on December 24, 2012

Copahue volcano activity could intensify

Authorities in Argentina and Chile have raised the alert at Copahue volcano  in Biobio region to the highest level after detecting continued seismic activity on Sunday.

  • Copahue first erupted on Saturday, showering ash on nearby villages and prompting many to evacuate.
  • “The intensity of seismic signals suggests the eruption in progress is on the smaller side [however] we cannot discount the possibility that the activity could turn into a larger eruption,” said a spokesman for the Chilean Geology and Mining Services.
  • The 2,970-meter volcano is in SW Argentina’s Neuquen province, near the Chilean border.
  • About 3,000 people live in the vicinity of the massive volcano, including  the residents of Copahue, the town of Caviahue and indigenous Mapuche communities.
  • The ash plume rose  to a height of about 1.5km (5,000ft) above the crater, said Chile’s emergency office (ONEMI).

Magnitude 7.7 Quake Strikes Queen Charlotte Islands, Canada

Posted by feww on October 28, 2012

Earthquake Measuring 7.7 Mw Strikes Queen Charlotte Islands Region generating a tsunami

FIRE-EARTH Forecast: Mega Quake measuring at least 8.8Mw could strike the region in the coming weeks with a probability of 0.75.

The powerful quake struck off Canada’s Pacific coast at a depth of about 16 km generating a tsunami, which forced  the authorities in Hawaii to order more than 100,000 people evacuate the shorelines.

  • Dozens of aftershocks, including at least 10 shocks measuring ≥5.0Mw had occurred, as of posting.
  • A Geophysicist at Tsunami Warning Center said the tsunami had caught scientists by surprise, Reuters reported.
  • “We thought that the earthquake was on land and when we learned that it was deeper undersea and we gathered more information, we had no choice but to issue a warning,” he said.

The Largest Earthquake in Canada

Canada’s largest earthquake (magnitude 8.1) since 1700, occurred on August 22, 1949 off the coast of BC. It occurred on the Queen Charlotte Fault (Canada’s equivalent of the San Andreas Fault) – the boundary between the Pacific and North American plates that runs underwater along the west coast of the Queen Charlotte Islands off the west coast of British Columbia. The shaking was so severe on the Queen Charlotte Islands that cows were knocked off their feet, and a geologist with the Geological Survey of Canada working on the north end of Graham Island could not stand up. Chimneys toppled, and an oil tank at Cumshewa Inlet collapsed. In Terrace, on the adjacent mainland, cars were bounced around, and standing on the street was described as “like being on the heaving deck of a ship at sea”. In Prince Rupert, windows were shattered and buildings swayed. —Natural resources of Canada

 OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN
 LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO
 BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE
 TO RAPID CURRENTS.  AS LOCAL CONDITIONS CAN CAUSE A WIDE
 VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST
 BE MADE BY LOCAL AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

Cleveland and Kīlauea Remain at ORANGE Alert

Posted by feww on April 6, 2012

Explosion destroys dome in Cleveland summit crater

Sudden explosions of blocks and ash may occur, while the volcano remains active, with the ash clouds rising to above 20,000 feet above sea level, AVO said.

  • Elevation:  5,676 ft (1,730 m)
  • Location: 52.8222° N, 169.945° W
  • Quadrangle: Samalga


Mt Cleveland. Photo taken at 18:00 UTC on 11 Mar 2012 while transiting north through Samalga pass. Several small explosions were detected in days prior to the time of the photo, but very little ash is observed on the upper flanks.  Credit:  Matthew Davis/NOAA.

KILAUEA VOLCANO

19°25’16″ N 155°17’13″ W,
Summit Elevation 4091 ft (1,247 m)
Current Volcano Ale,rt Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary for past 24 hours:  The summit continued to inflate slowly while back-to-back DI events and sympathetic summit lava lake oscillations continued. Overnight, glow was visible within the Halema`uma`u gas plume and from sources within Pu`u `O`o crater. To the southeast, surface flows continued to be active on the pali and the coastal plain; there was no ocean entry. Seismic tremor levels were low; gas emissions were elevated: HVO


Kīlauea Volcano.  Active flows continued over a broad area on the coastal plain on April 5, 2012.  “This composite image combines a normal photograph and a thermal image to show the areas of active breakouts. Yellow areas are active flows while red areas are inactive, but still warm, flows. The flow front in the lower right was 1.6 km (1 mile) from the ocean,” HVO said.

Alert Level Increased for Iliamna Volcano, AK

Iliamna Activity – Color Code YELLOW Alert Level ADVISORY

Since January 2012 the earthquake rate at Iliamna Volcano has steadily increased and now exceeds normal background levels.

NOTHING SACRED in SCIENTIFIC COMMUNITY

Posted by feww on March 9, 2012

on November 19, 2011 FIRE-EARTH posted the following forecast:

Major Geological Events Forecast for Western U-S

Earlier today, MSNBC posted the following:

Quake catastrophe like Japan’s could hit Pacific Northwest, new data show

We won’t ask, what new data? However, note the researchers’ inappropriate use of the term “mirror image,” which they almost certainly borrowed from earlier FIRE-EARTH forecast [https://feww.wordpress.com/2009/08/19/new-round-of-geo-assualt/] but used it in the wrong context. Their slick prophecy about the time of occurrence, “it could be sooner rather than later,” is also mysteriously consistent with the above FIRE-EARTH forecast(i.e, short term). Though the researchers fail to say how they arrived at their conclusion or where it came from.

Quake catastrophe like Japan’s could hit Pacific Northwest, new data show

“It’s just like Japan, only a mirror image,” said Gerard Fryer, a geophysicist at the University of Hawaii and the Pacific Tsunami Warning Center.

“Where are we here? Are we close or are we not close?” he asked. “I think the suspicion is that it could be sooner rather than later.” [Based on what assumptions?]
[...]
Like Fryer, he called the Pacific Northwest trench a “mirror image” of the Japanese trench — except potentially even more dangerous.

“In this mirror image, one can see that if the same earthquake occurred in Cascadia, the fault would rupture to a significant distance inland, since the Cascadia trench sits much closer to the coastline than the trench off the coast of Japan,” Anderson said.

NOTHING SACRED in SCIENTIFIC COMMUNITY

MAJOR GEOLOGICAL EPISODES that are likely to IMPACT THE ENTIRE WESTERN UNITED STATES, as forecast by FIRE-EARTH, will comprise a number of discrete events, including at least several ‘surprises.’

Readers who are in doubt about the originality of the research at Hawaii and Nevada universities, could put their minds at rest of course by emailing the two academics named in the MSNBC article and asking them for details of those events (e.g, type, sequence, scale, probability of occurrence…).

JAPAN Region Earthquake Forecast

In Japan Earthquake Forecast, posted on February 14, 2012, we said:

A Note to Seismologists at Tokyo University and Tohoku University, Japan

FIRE-EARTH MODERATORS STRONGLY URGE YOU TO PRODUCE  ORIGINAL RESEARCH AND REFRAIN FROM PIGGYBACK RIDING ON OUR FORECASTS.

ONCE AGAIN, YOU HAVE MADE US EXTREMELY RELUCTANT TO POST ANY FUTURE EARTHQUAKE FORECAST.

Staff at Research Center for Prediction of Earthquakes & Volcanic Eruptions, Graduate School of Science, Tohoku University are strongly advised to focus on probability of the next major earthquake in China.

How could researchers from 4 different universities located on the opposite ends of Pacific Ocean, about 9,000km (5,500 miles) apart bluff their way in identical ways, fooling their respective taxpayers into believing they know their science? Is there a common link between Japan earthquake researchers, and their counterparts in Western U.S.?

Interestingly, it seems there is a solid link. Read the rest of MSNBC article Quake catastrophe like Japan’s could hit Pacific Northwest, new data show.

Dominican Republic Quake Report

Posted by feww on April 3, 2010

Serial No  1,528. If any posts are blocked in your country, please drop us a line.

Correction:

An earlier report of a magnitude 8.0 earthquake in the Dominican Republic that was posted on Fire-Earth was sourced from an automatically generated bulletin broadcast by the European Commission’s Global Disaster Alert and Coordination System – the report now appears to be FALSE

According to other monitoring sources, an 8.0Mw quake has NOT occurred in the region.

Details as they appeared on  EC’s Disaster Website:

Earthquakes: Worst Disaster Type in Past Decade

Posted by feww on January 29, 2010

Earthquakes caused the deadliest disasters in 2000-09 decade: UNISDR

In its recent News Brief, United Nations International Strategy for Disaster Reduction Secretariat (UNISDR) reported that about 60 per cent of the people killed by disasters in the past decade died as a result of earthquakes.

“Earthquakes are the deadliest natural hazard of the past ten years and remain a serious threat for millions of people worldwide as eight out of the ten most populous cities in the world are on earthquake fault-lines,” said Margareta Wahlström, UN Special Representative of the Secretary-General for Disaster Risk Reduction.

“Disaster risk reduction is an indispensable investment for each earthquake-prone city and each community. Seismic risk is a permanent risk and cannot be ignored. Earthquakes can happen anywhere at any time. Risk reduction will be a main priority in the Haiti reconstruction process, and we will be working with our partners to ensure that it is central in the reconstruction.”

The Center for Research on Epidemiology of Disasters (CRED) has released the following statistics covering the past 10 years:

Number of disasters for 2000-20009 period: 3,852 disasters

  • Death toll from the disasters: 780,000 people
  • Total number of people affected by the disasters: about a thirs of the planet’s population (more than two billion people)
  • Cost of the damage caused by the disasters: About 1 trillion (US$960 billion).

The worst hit continent in terms of human losses:  Asia, accounting for 85 per cent of all fatalities.

Disaster Types

  • The worst category: Earthquakes, accounting for 60 percent of the fatalities
  • Second Worst Disaster Category:  Storms, accounting for 22 percent of the deaths.
  • Third deadliest: Extremes of Temperature, accounting for 11  percent of the casualties.

The deadliest disasters of the 2000-2009 decade:

  • Indian Ocean Tsunami:   Struck several countries in Asia (2004),  leaving 226,408 dead
  • Cyclone Nargis: Struck  Myanmar (2008), killing 138,366 people
  • Sichuan earthquake:  China (2008) killed at least 87,476 people
  • Pakistan (2005) earthquake: Killed 73,338 people w
  • Heat waves in Europe (2003): Killed 72,210

“The number of catastrophic events has more than doubled since the 1980-1989 decade. In contrast, the numbers of affected people have increased at a slower rate. This may be due to better community preparedness and prevention,” said Professor Guha-Sapir, Director of CRED.

Of the more than two billion affected people

  • 44 per cent were affected by floods
  • 30 per cent by droughts
  • ONLY 4 per cent by earthquakes

The  death toll for the last 3 decades (annual average)

  • 2000 decade: 78,000 people per year(ppy)
  • 1990s decade: 43,000 ppy
  • 1980s decade: 75,000  (worsened by two major droughts and famines in Ethiopia and Sudan)

Natural Hazard Events (annual average) and Estimated Economic  Damage

  • 2000 decade: 385  at a cost of US$96 billion
  • 1990 decade: 285  at a cost of US$99 billion
  • 1980 decade: 165  at a cost of US$39 billion

In 2009, some 10,416 people were killed in 327 disasters and  a further 113 million others were affected. Cost of the economic damage:  US$34.9 billion. {there were no major disasters). the total number of people killed and affected by disasters was lower than in 2008, as no major disaster occurred.

In contrast, the 2000-2008 annual averages were 85,535 (deaths), 229,792,397 (affected) and US$102.7 billion (economic damages).

The worst disaster in 2009

The worst disaster in 2009 (highest death toll) was the 7.6 magnitude earthquake that struck the island of Sumatra, Indonesia, on 30 September, killing at least 1,100 people.  It was followed by typhoons Morakot, Ketsana and Parma and numerous floods that killed many in Asia, which was home to six of the top 10 countries with the highest number of disaster-related deaths.

Most populous cities on EQ fault-lines (A-Z): Delhi, Jakarta, Kolkata Mexico City, Mumbai, New York, Shanghai and Tokyo.

Note: IF the numbers of fatalities/casualties in a given disaster are claimed to be larger than a few hundreds, and no video or photographic evidence is presented to support the claim, those figures should be carefully analyzed. Governments and aid organizations invariably exaggerate the casualty figures to maximize the inflow of aid and donations for self-serving purposes and interests other than those of the victims.

Yellowstone eruption may cover 60 pct of US: FEWW

Posted by feww on December 14, 2009

The next cataclysmic event at Yellowstone supervolcano could cover about  60 percent of the continental US in volcanic materials —Fire Earth

.

Yellowstone’s Plumbing Exposed

Plume Slants NW; Magma Body Bigger than Thought

Dec. 14, 2009 – The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup.

A related University of Utah study used gravity measurements to indicate the banana-shaped magma chamber of hot and molten rock a few miles beneath Yellowstone is 20 percent larger than previously believed, so a future cataclysmic eruption could be even larger than thought.


Seismic imaging was used by University of Utah scientists to construct this picture of the Yellowstone hotspot plume of hot and molten rock that feeds the shallower magma chamber (not shown) beneath Yellowstone National Park, outlined in green at the surface, or top of the illustration. The Yellowstone caldera, or giant volcanic crater, is outlined in red. State boundaries are shown in black. The park, caldera and state boundaries also are projected to the bottom of the picture to better illustrate the plume’s tilt. Researchers believe “blobs” of hot rock float off the top of the plume, then rise to recharge the magma chamber located 3.7 miles to 10 miles beneath the surface at Yellowstone. The illustration also shows a region of warm rock extending southwest from near the top of the plume. It represents the eastern Snake River Plain, where the Yellowstone hotspot triggered numerous cataclysmic caldera eruptions before the plume started feeding Yellowstone 2.05 million years ago.

The study’s of Yellowstone’s plume also suggests the same “hotspot” that feeds Yellowstone volcanism also triggered the Columbia River “flood basalts” that buried parts of Oregon, Washington state and Idaho with lava starting 17 million years ago.

Those are key findings in four National Science Foundation-funded studies in the latest issue of the Journal of Volcanology and Geothermal Research. The studies were led by Robert B. Smith, research professor and professor emeritus of geophysics at the University of Utah and coordinating scientist for the Yellowstone Volcano Observatory.

“We have a clear image, using seismic waves from earthquakes, showing a mantle plume that extends from beneath Yellowstone,” Smith says.

The plume angles downward 150 miles to the west-northwest of Yellowstone and reaches a depth of at least 410 miles, Smith says. The study estimates the plume is mostly hot rock, with 1 percent to 2 percent molten rock in sponge-like voids within the hot rock.

Some researchers have doubted the existence of a mantle plume feeding Yellowstone, arguing instead that the area’s volcanic and hydrothermal features are fed by convection – the boiling-like rising of hot rock and sinking of cooler rock – from relatively shallow depths of only 185 miles to 250 miles.

The plume is mostly hot rock with about 1 to 2 percent molten rock. Researches believe “blobs” of hot rock slowly detach from the top of the plume and rise upward to recharge the magma chamber that lies from 3.7 to 10 miles beneath Yellowstone. The chamber is also mostly hot rock, but with a sponge-like structure containing about 8 to 15 percent molten rock. Photo Credit: University of Utah

The Hotspot: A Deep Plume, Blobs and Shallow Magma

Some 17 million years ago, the Yellowstone hotspot was located beneath the Oregon-Idaho-Nevada border region, feeding a plume of hot and molten rock that produced “caldera” eruptions – the biggest kind of volcanic eruption on Earth.

As North America slid southwest over the hotspot, the plume generated more than 140 huge eruptions that produced a chain of giant craters – calderas – extending from the Oregon-Idaho-Nevada border northeast to the current site of Yellowstone National Park, where huge caldera eruptions happened 2.05 million, 1.3 million and 642,000 years ago.

These eruptions were 2,500, 280 and 1,000 times bigger, respectively, than the 1980 eruption of Mount St. Helens. The eruptions covered as much as half the continental United States with inches to feet of volcanic ash. The Yellowstone caldera, 40 miles by 25 miles, is the remnant of that last giant eruption.

The new study reinforces the view that the hot and partly molten rock feeding volcanic and geothermal activity at Yellowstone isn’t vertical, but has three components:

  • The 45-mile-wide plume that rises through Earth’s upper mantle from at least 410 miles beneath the surface. The plume angles upward to the east-southeast until it reaches the colder rock of the North American crustal plate, and flattens out like a 300-mile-wide pancake about 50 miles beneath Yellowstone. The plume includes several wider “blobs” at depths of 355 miles, 310 miles and 265 miles.”This conduit is not one tube of constant thickness,” says Smith. “It varies in width at various depths, and we call those things blobs.”
  • A little-understood zone, between 50 miles and 10 miles deep, in which blobs of hot and partly molten rock break off of the flattened top of the plume and slowly rise to feed the magma reservoir directly beneath Yellowstone National Park.
  • A magma reservoir 3.7 miles to 10 miles beneath the Yellowstone caldera. The reservoir is mostly sponge-like hot rock with spaces filled with molten rock”It looks like it’s up to 8 percent or 15 percent melt,” says Smith. “That’s a lot.”

Researchers previously believed the magma chamber measured roughly 6 to 15 miles from southeast to northwest, and 20 or 25 miles from southwest to northeast, but new measurements indicate the reservoir extends at least another 13 miles outside the caldera’s northeast boundary, Smith says.

He says the gravity and other data show the magma body “is an elongated structure that looks like a banana with the ends up. It is a lot larger than we thought – I would say about 20 percent [by volume]. This would argue there might be a larger magma source available for a future eruption.”

Images of the magma reservoir were made based on the strength of Earth’s gravity at various points in Yellowstone. Hot and molten rock is less dense than cold rock, so the tug of gravity is measurably lower above magma reservoirs.

The Yellowstone caldera, like other calderas on Earth, huffs upward and puffs downward repeatedly over the ages, usually without erupting. Since 2004, the caldera floor has risen 3 inches per year, suggesting recharge of the magma body beneath it.

How to View a Plume

Seismic imaging uses earthquake waves that travel through the Earth and are recorded by seismometers. Waves travel more slowly through hotter rock and more quickly in cooler rock. Just as X-rays are combined to make CT-scan images of features in the human body, seismic wave data are melded to produce images of Earth’s interior.

The study, the Yellowstone Geodynamics Project, was conducted during 1999-2005. It used an average of 160 temporary and permanent seismic stations – and as many as 200 – to detect waves from some 800 earthquakes, with the stations spaced 10 miles to 22 miles apart – closer than other networks and better able to “see” underground. Some 160 Global Positioning System stations measured crustal movements.

By integrating seismic and GPS data, “it’s like a lens that made the upper 125 miles much clearer and allowed us to see deeper, down to 410 miles,” Smith says.

The study also shows warm rock – not as hot as the plume – stretching from Yellowstone southwest under the Snake River Plain, at depths of 20 miles to 60 miles. The rock is still warm from eruptions before the hotspot reached Yellowstone.

A Plume Blowing in the 2-inch-per-year Mantle Wind

Seismic imaging shows a “slow” zone from the top of the plume, which is 50 miles deep, straight down to about 155 miles, but then as you travel down the plume, it tilts to the northwest as it dives to a depth of 410 miles, says Smith.

That is the base of the global transition zone – from 250 miles to 410 miles deep – that is the boundary between the upper and lower mantle – the layers below Earth’s crust.

At that depth, the plume is about 410 miles beneath the town of Wisdom, Mont., which is 150 miles west-northwest of Yellowstone, says Smith.

He says “it wouldn’t surprise me” if the plume extends even deeper, perhaps originating from the core-mantle boundary some 1,800 miles deep.

Why doesn’t the plume rise straight upward? “This plume material wants to come up vertically, it wants to buoyantly rise,” says Smith. “But it gets caught in the ‘wind’ of the upper mantle flow, like smoke rising in a breeze.” Except in this case, the “breeze” of slowly flowing upper mantle rock is moving horizontally 2 inches per year.

While the crustal plate moves southwest, the warm, underlying mantle slowly boils due to convection, with warm areas moving upward and cooler areas downward. Northwest of Yellowstone, this convection is such that the plume is “blown” east-southeast by mantle convection, so it angles upward toward Yellowstone.

Scientists have debated for years whether Yellowstone’s volcanism is fed by a plume rising from deep in the Earth or by shallow churning in the upper mantle caused by movements of the overlying crust. Smith says the new study has produced the most detailed image of the Yellowstone plume yet published.

But a preliminary study by other researchers suggests Yellowstone’s plume goes deeper than 410 miles, ballooning below that depth into a wider zone of hot rock that extends at least 620 miles deep.

The notion that a deep plume feeds Yellowstone got more support from a study published this month inicating that the Hawaiian hotspot – which created the Hawaiian Islands – is fed by a plume that extends downward at least 930 miles, tilting southeast.

A Common Source for Yellowstone and the Columbia River Basalts?

Based on how the Yellowstone plume slants now, Smith and colleagues projected on a map where the plume might have originated at depth when the hotspot was erupting at the Oregon-Idaho-Nevada border area from 17 million to almost 12 million years ago.

They saw overlap, between the zones within the Earth where eruptions originated near the Oregon-Idaho-Nevada border and where the famed Columbia River Basalt eruptions originated when they were most vigorous 17 million to 14 million years ago.

Their conclusion: the Yellowstone hotspot plume might have fed those gigantic lava eruptions, which covered much of eastern Oregon and eastern Washington state.

“I argue it is the common source,” Smith says. “It’s neat stuff and it fits together.”

Smith conducted the seismic study with six University of Utah present or former geophysicists – former postdoctoral researchers Michael Jordan, of SINTEF Petroleum Research in Norway, and Stephan Husen, of the Swiss Federal Institute of Technology; postdoc Christine Puskas; Ph.D. student Jamie Farrell; and former Ph.D. students Gregory Waite, now at Michigan Technological University, and Wu-Lung Chang, of National Central University in Taiwan. Other co-authors were Bernhard Steinberger of the Geological Survey of Norway and Richard O’Connell of Harvard University.

Smith conducted the gravity study with former University of Utah graduate student Katrina DeNosaquo and Tony Lowry of Utah State University in Logan.

Powerful Earthquake Strikes Tonga

Posted by feww on November 25, 2009

Earthquake Measuring Up to M 7.1 Strikes Near NUKU’ALOFA, Tonga

A powerful earthquake measuring up to 7.1 Mw struck  about 135 km (85 miles) ENE of NUKU’ALOFA, Tonga at a depth of 10 km on  November 24, 2009 at 12:47 UTC.

The quake was followed by at least two aftershocks, the stronger of which measured up to 5.8 Mw.

Tsunami Evaluation:

The Pacific Tsunami Warning Center/NOAA/NWS Evaluated the Tsunami Hazard as follows:

NO DESTRUCTIVE WIDESPREAD TSUNAMI THREAT EXISTS BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

HOWEVER – EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN A HUNDRED KM OF THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS POSSIBILITY AND TAKE APPROPRIATE ACTION.

FEWW Comment: Does the SW Pacific region including Tonga, Fiji, and Samoan Islands regions act as a ‘planetary seismic shock damper?’  How much longer will the service last?

The Largest Earthquake in Canada

Canada’s largest earthquake (magnitude 8.1) since 1700, occurred on August 22, 1949 off the coast of BC. It occurred on the Queen Charlotte Fault (Canada’s equivalent of the San Andreas Fault) – the boundary between the Pacific and North American plates that runs underwater along the west coast of the Queen Charlotte Islands off the west coast of British Columbia. The shaking was so severe on the Queen Charlotte Islands that cows were knocked off their feet, and a geologist with the Geological Survey of Canada working on the north end of Graham Island could not stand up. Chimneys toppled, and an oil tank at Cumshewa Inlet collapsed. In Terrace, on the adjacent mainland, cars were bounced around, and standing on the street was described as “like being on the heaving deck of a ship at sea”. In Prince Rupert, windows were shattered and buildings swayed. —Natural resources of Canada

Seventh Powerful Quake Hits Japan Region

Posted by feww on October 30, 2009

Powerful Earthquake measuring up to 7.2 Mw Strikes  RYUKYU ISLANDS, JAPAN

Background:

A powerful earthquake measuring up to 7.2 Mw occurred in Ryukyu Islands, Japan, about 280 km (175 miles) SSW of Kagoshima, Kyushu, at a depth of 35 km (21.7 miles), on Friday, October 30, 2009 at 07:03 UTC.

Referring to an earlier forecast, FEWW Moderators believe an additional series of 6 – 7 quakes measuring ≥ 6.0 Mw could strike Japan region in the coming weeks.

FEWW Moderators had previously anticipated more powerful earthquakes in the region, including as many as 10 additional magnitude 6+ quakes to strike the region in the coming weeks.

A moderate earthquake measuring up to 5.3 Mw struck near 29.165°N, 130.061°Eclose to the latest event on Sunday, October 25, 2009 at 06:17 UTC at a depth of about 47.5 km (29.5 miles).

1. About 52 percent of the total energy released during the listed events came from the Vanuatu earthquake measuring 8.2 Mw.

2. A combined total of 89 percent of the energy released came from the two earthquakes highlighted in shades of blue, measuring 8.2 and 8.1 Mw respectively.

Earthquakes: Human Enhanced Disasters – UPDATE 3 Oct 2009

Posted by feww on October 3, 2009

Previous Updates:

As of Saturday, October 3, virtually no help has reached rural areas.

Up to 4,000 people (figure provided by UN officials) are feared trapped under hundreds of thousands of tons of rubble after a magnitude 7.9 quake destroyed more than 25,000 houses and buildings across  seven districts on a 100-km stretch along  the western coast of Sumatra island, Indonesia on September 30, 2009.

“We estimate there are still eight people trapped alive under Ambacang Hotel. We are still trying hard to evacuate them,” a rescuer  told reporters, in Padang.

Situation in the Disaster Areas:

  • Power outages are reported in most districts, phone lines are down.
  • Water and food are in very short supply.
  • Villagers  are digging out the dead with bare hands.
  • Cost of recovery operation is estimated at least $400 million, according to Indonesia’s Vice President.
  • Rural areas are cut off by massive landslides, which have reportedly blocked roads and destroyed a number of villages, killing about 300 people.
  • There are no structures standing in the district of Pariaman, a hilly community of about 370,000 about 80 km north of Padang, an AP journalist has reported.

Earthquakes: Human Enhanced Disasters – UPDATE 2 Oct 2009

Posted by feww on October 2, 2009

Sumatra Double Earthquakes

FEWW Moderators believe it’s highly probable that another 2 or more strong to powerful quakes could strike the region in the coming days. Padang and other coastal towns in Sumatra and Java must also prepare for a possible tsunami.

At least 1,200 bodies have been recovered following widespread damage after a magnitude 7.9 quake  struck southern Sumatra, Indonesia, on Wednesday, according to the officials.

The Death Toll Could Reach Many Thousands


There are no reports of deaths from the 6.8 magnitude quake that struck southern Sumatra  on Thursday. However. a local radio station reported that a dozen 12 people had been injured and up to 75 building damaged in  the town of Jambi.

“People are trapped and screaming for help but they are below huge slabs which will take heavy equipment to move,” an aid worker said.

“I saw dozens of the biggest buildings collapsed in town. Most of the damage is concentrated in the commercial center market, which was fully packed,” he said.

Images that will be repeated throughout the world, again, and again

Regional Economy

West Sumatra, a major producer of crude palm oil, is also affected economically.

Indonesia’s finance minister Sri Mulyani said: “This region has been damaged seriously, including its infrastructure,” adding that her government has allocated $25 million over two month for emergency operations.

Powerful Earthquake Strikes Southern Sumatra, Indonesia

Posted by feww on September 30, 2009

More Megaquakes May Strike PRF Anytime

Magnitude 7.9 earthquake strikes southern Sumatra, Indonesia

Magnitude 7.9 earthquake struck southern Sumatra, Indonesia, 50 km (30 miles) WNW of Padang, at a depth  of about 85 km on Wednesday, September 30, 2009 at 10:16 UTC, USGS/EHP reported.

Only hours ago, having briefly analyzed details of the Samoan earthquake, FEWW had foretasted that up to 3 more powerful quakes could strike the Pacific Ring of Fire in 2009.

Four weeks ago a deadly earthquake measuring  7.3 to 7.6 Mw struck off the coast of Java, Indonesia, killing more than 80 people and injuring at least another 1,250.

Tsunami Warning

Pacific Tsunami Warning Center (NOAA) has issued a tsunami warning based on the size and location of the earthquake for countries bordering Indian Ocean: Indonesia, India, Thailand and Malaysia.

Damage Report

“People are panicking. They are running out of the buildings… There are many collapsed buildings,” an eye-witness in Padang told a local TV station.

“Hundreds of houses have been damaged along the road. There are some fires, bridges are cut and there is extreme panic here maybe because water pipes are broken and there is flooding in the streets,” another witness told Reuters.

“Hundreds of houses have been damaged along the road,” another eye-witness in Padang said.

“There are some fires, bridges are cut and there is extreme panic here maybe because water pipes are broken and there is flooding in the streets.”

Padang has a population of just under 1,000,000 people. There were no reports of casualties as of posting; however, given that so many buildings have collapsed, it’s more than likely that many people would have been killed or injured.

According to a local report, power and phone lines are down in Pandang and several other parts of Indonesia.

The mainshock was followed by a strong aftershock measuring 6.0  GFZ Potsdam/ Earthquake Bulletin reported. More strong aftershocks are highly probable.

Samoa Tsunami Update

Posted by feww on September 30, 2009

Samoa Tsunami: Images and Update

The tsunami occurred after a  massive earthquake measuring up to 8.4 Mw struck in the Samoa Islands Region about 185 km (115 miles) east-northeast of Hihifo, Tonga and 195 km (125 miles) south  of APIA, Samoa.

According to various reports

  • A series of of three or more tsunamis struck into the Pacific islands of American and Western Samoa destroying villages
  • At least 4 villages were wiped off.
  • Dozens of people, including many children, were  swept out to sea
  • As many as 100 people have been killed, with many hundred more injured
  • U.S. President Obama has declared American Samoa a major disaster area
  • A 4-meter (13-foot) wave hit the  northern coast of Tonga.
  • A Pacific-wide tsunami warning was issued, but later canceled.
  • Japan’s Meteorological Agency (JMA) issued a local tsunami warning for its east coast, warning of a possible tsunami waves measuring up to 50cm.
  • The Pacific Tsunami Warning Center later reported that small tsunami waves had indeed reached Hawaii, and warned swimmers and boats that the waves could prove dangerous.
  • Several  South Pacific island nations reported rising sea levels.

Cont…

  • The southern section of American Samoa’s main Tutuila island  was “devastated,” its governor said, with at least 24 people  killed and twice as many injured.
  • As video images come in,  the extent of the damage becomes more evident with homes destroyed by the waves, large fishing boats hurled ashore, and vehicles piled on top of each other.
  • “Some areas have been flattened and the tsunami brought a lot of sand onshore, so there have been reports the sand has covered some of the bodies,” Western Samoa’s disaster management office said.
  • “They are still continuing the searches for any missing bodies in the area,” they said, adding that the southern section of their country’s main island of Upolu was the worst hit.
