Irish Sea earthquakes send tremors across British Isles

Posted by feww on August 26, 2013

Earthquakes felt both in Ireland and the UK

Two earthquakes struck in the Irish Sea early Sunday, said the British Geological Survey.

The strongest shock measured 3.3 on the Richter scale at a depth of about 5km some 25km off the coast of Blackpool at 10.58am (BST), and was reportedly felt by people on the British mainland.

An earlier quake measuring about 2.4 magnitude at a depth of 3km occurred about 4 hours earlier.

[Really?]

“The Irish National Seismic Network , which monitors seismic activity, has said that today’s earthquakes were ‘most likely the result of glacial rebound, the process whereby stresses built up the weight of glaciers from the last Ice Age are slowly released,'” said a report.

“It was not as strong as the Irish Sea earthquake on May 29th this year. The epicenter of the quake, which registered at magnitude 3.8, was 15km away from the town of Abersoch in Gwynedd, the British Geological Survey (BGS) said.”

A magnitude 4.0 quake struck the Iceland Region (62.90°N, 25.18°W) on Sunday at 07:00 UTC.

Local geologists would be advised to investigate connection between those quakes.

State of Disaster Declared in Solomon Islands

Posted by feww on February 8, 2013

Significant aftershocks continue to pound Santa Cruz Islands region as govt. declares a State of Disaster

Solomon Islands government has declared a State of Disaster for Santa Cruz Islands after a meter-high tsunami triggered by a magnitude 8.0 quake engulfed the region on Wednesday.

  • At least nine people are dead and many are missing after the tsunami damaged or destroyed more than 20 villages.
  • Officials say scope of the disaster is much worse than initially thought and they  still don’t know the fate of the more outlying villages in the reef islands.
  • The tsunami has wept away entire villages, spreading debris everywhere.
  • “The force behind the meter-high [tsunami] wave swept everything in its path, especially in low-lying areas,” said an official.
  •  “Many people have no clothes at all, everything was washed away.”
  • Authorities say about 7,000 people have been displaced as a result of the tsunami,  but the number could reach much higher.

Earthquakes Leave Hundreds Dead or Injured in Iran

Posted by feww on August 11, 2012

Disaster Calendar – 11 August 2012

SYMBOLIC COUNTDOWN: 1,313 Days Left

[August 11, 2012] Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016.  SYMBOLIC COUNTDOWN: 1,313 Days Left to the ‘Worst Day’ in Human History…

Two strong quakes struck NW Iran, killing about 200, injuring 1,500

The quakes struck near the city of Tabriz (pop: ~1.5 million), capital of East Azerbaijan province and the country’s fourth most populated city, destroying or damaging about 70 outlying villages.

  • First quake measuring 6.4Mw struck 20 km (12 miles) WSW of Ahar, and 60 km (37 miles) ENE of Tabriz, Iran.
  • Second quake measuring 6.3Mw struck 32 km (19 miles) WSW of Ahar, and 48 km (29 miles) ENE of Tabriz, according to USGS.
  • Both quakes struck at depths of less than 10km.
  • The second quake struck about 12 minutes after the first at 12:34UTC, August 11, 2012.
  • The death toll is expected to rise, as many people are still trapped in the rubble, officials told reporters.
  • The quakes have left at least 20,000 people homeless,
  • At least a dozen aftershock have struck near the epicenter at Armenia-Azerbaijan-Iran border region, as of posting.

Indian Ocean Tsunami Travel Time Map


A magnitude 9.1 Mw earthquake occurred off the west coast of Sumatra, Indonesia, on December 26, 2004. It was the fourth largest earthquake in the world since 1900 and the largest since the 1964 Prince William Sound, Alaska, earthquake. The earthquake generated a tsunami that caused more casualties than any other in recorded history. The tsunami was recorded nearly world-wide on tide gauges in the Indian, Pacific and Atlantic Oceans. In total, more than 227,8980 people were killed or missing and 1,126,900 were displaced by the earthquake and subsequent tsunami in 14 countries in South Asia and East Africa. Source:  NGDC

A VOLCANIC ERUPTION IN ARKANSAS?

“…On the third day of December last, a singular noise was heard here. It has been differently described by those who heard it as like a blast in a wall, the explosion of a meteor, or a single distant clap of heavy thunder. So far as ascertained, the nearer the center or place of explosion, there was a rumbling and a sensible vibration of the earth.

“Much speculation was had as to its cause. It was not probable that it was thunder, for it was mid-winter and the sky was clear; nor blasting in a well, for people do not work in wells in the wet and wintry season. Upon inquiry we found that the explosion had been heard as far as Fort Gibson, and generally in a circle whose diameter is two hundred miles and expected to find some notice of it in the papers of your city. The other day, Col. Logan, of Scott County, visited our city and gave us an apparent solution of the mystery. “It appears, from his statement, that Mr. Wm. Gipson, while bear hunting on Christmas day, attempted to cross Dry Creek, situated in T 5 N, R. 26 W., but found the mountain to be on fire. Gipson describes it as sending forth smoke at the top which at night time has a ruddy glare and is visible for miles…The ground is heated, and the sides of the mountain are numerous fissures, through which vapor is constantly escaping…”  [Excerpts from an article printed by the Arkansas Gazette, January 15, 1856.]

Devils Hole Tsunami and the Pupfish

Posted by feww on May 12, 2010

How El Mayor-Cucapah Earthquake Generated a Pupfish Tsunami

University of Arizona researchers caught the April 4 El Mayor-Cucapah earthquake on videotape. To a group of rare, critically endangered, inch-long fish that is believed to exist only in “Devils Hole,” a crack in the ground in Nevada’s Mojave Desert, the quake had unleashed a massive tsunami—Fire-Earth

The following is a news release by the University of Arizona :

‘Tsunami’ video sheds light on struggling pupfish

For the first time, an earthquake was recorded live in Devils Hole, home to the only population of a critically endangered pupfish species

To most people in the southwestern U.S., the April 4 El Mayor-Cucapah earthquake felt like a rocking of the ground. But on a group of inch-long fish that exist nowhere else on Earth outside of “Devils Hole,” a crack in the ground in Nevada’s Mojave Desert, it unleashed a veritable tsunami.

University of Arizona researchers were able to catch the event on cameras installed above and below the water’s surface to monitor the fish’s spawning behavior. It is the first time in decades of research at Devils Hole that an earthquake was captured on video.

The event provided the researchers with a rare opportunity to study how a critically endangered species copes when its confined habitat is shaken up in a dramatic way.

The Devils Hole pupfish spend their lives in what likely is the “smallest habitat of a vertebrate species,” according to UA professor Scott Bonar, who runs a pupfish population recovery program at UA’s School of Natural Resources and the Environment.

That habitat is the “spawning shelf” – a submerged rock surface covered by a mere two feet of water. It’s here that the pupfish feed and go about their breeding activity. The shelf forms the only shallow part of a freshwater pool measuring 10 by 50 feet that marks the entrance to the Devils Hole cave.

The pool provides a window into the extensive carbonate aquifer within the Amargosa Valley groundwater basin. Despite explorations undertaken by cave divers, no one has been able to probe the depths of the Devils Hole cave system, although they are known to plunge beyond 500 feet.

Making waves

On most days, Devils Hole looks like a glassy surface of crystal-clear water, shimmering with an unearthly, iridescent turquoise hue at the bottom of a crack in the rocks 50 feet below ground level.

But on April 4, 16 minutes after the shockwaves arrived in the Mojave Desert 300 miles north of the epicenter near Mexicali in Baja California, serenity gave way to turmoil in the small world of the Devils Hole pupfish.

“The water was sloshing back and forth so hard it splashed against our cameras four feet above the waterline,” said Ambre Chaudoin, a graduate student in fisheries conservation and management with the U.S. Geological Survey (USGS) Arizona Cooperative Fish and Wildlife Research Unit at the UA.

“The quake swept the shelf clean from algae, shuffling the silt and cobble around. Such disturbance can be important because the spawning shelf is less than 13 feet long and 7 feet wide, smaller than many walk-in closets. ”

Chaudoin and fellow USGS researcher Olin Feuerbacher, a senior research specialist for the Cooperative, conduct the pupfish monitoring study as part of a joint effort to protect the Devils Hole pupfish population. Under its land grant mission, the UA is tasked with research aimed to learn how the fish might be propagated in captivity and what factors may threaten their survival as a species.

The study is being conducted by the USGS Arizona Fish and Wildlife Cooperative Research Unit and is funded by the U.S. Fish and Wildlife Service, in partnership with the National Park Service and the Nevada Department of Wildlife.

Struggling to survive

Devils Hole pupfish numbered about 400-500 until the late 1960s, when the water level in the pool dropped in response to pumping of nearby irrigation wells. Only a U.S. Supreme Court order prevented the shallow spawning shelf from falling dry, thus saving the species from extinction.

Since then, the Devils Hole pupfish have struggled to survive.

Chaudoin and Feuerbacher make the trip from Tucson to Devils Hole twice a month to check on the measuring equipment and download data. They happened to be on location conducting pupfish behavior surveys the day of the April 4 earthquake. Just 10 minutes before the quake struck, they had reconnected the video cameras to their recording position inside the pool.

“The fish begin to move out of the camera’s view as the waves start getting bigger, and then, because of all the sediment being stirred up, you can’t see the fish. As the waves grew stronger, the fish likely moved into deeper waters,” Chaudoin said.

To see video clips, visit the U.S. Geological Survey website.

“Although we knew from water-level records that earthquakes influenced Devils Hole in the past, this is the first time we’ve caught one on video,” said Paul Barrett, a Fish and Wildlife Service biologist who leads the Devils Hole Pupfish Recovery Team. “It may provide great insight into how the wave action cleans the fine silt off of the shelf.”

Although the violent sloshing during the quake washed away algae that are essential to the food web of the critically endangered fish, algae have already grown back substantially, according to biologists.

Spawning pupfish: Canaries in coal mine

“We monitor when the fish spawn and when they don’t, and the environmental factors present at the time,” Chaudoin said. “We keep track of certain physical parameters in the water, such as oxygen and temperature. We also study the influence of day and night light cycles on the fish’s behavior.”

Disentangling the complex interactions between environmental factors and the pupfish’s behavior is not a simple task. It appears a combination of several factors, such as oxygen concentration in the water, temperature and length of daylight, all interact to trigger spawning behavior.

“Our goal is to monitor all these factors on an ongoing basis so we can obtain a continuous record,” Feuerbacher said. “In the past, research at Devils Hole has focused on personal observations and measurements taken at certain times, which gives you only snapshots of what is happening at those times.”

Chaudoin added: “The implications of the studies at Devils Hole reach far beyond protecting these little fish. In a sense, they are canaries in a coal mine. Because this habitat is so isolated and contained, we notice changes right away. In a sense, it’s a living lab where we can study food webs and ecology, and the lessons we learn help us protect other habitats as well.”

Quakes with a purpose

“Quakes can serve a useful purpose in shaking silt and other fine particles that have washed into Devils Hole off of the spawning shelf and into the deeper waters,” said Barrett. “This frees important space between the substrate particles where the Devils Hole pupfish larvae seek refuge.”

In fact, he added, after the April 4 Mexicali quake, the National Park Service recorded a slight increase in larval abundance as compared to a similar survey a few weeks before the earthquake occurred.

Federal and state surveys done within a week after the earthquakes revealed about 118 fish in the pool, compared to about 70 the year before. Also, biologists saw newly hatched larval fish and evidence that the fish were spawning.

Despite increasing numbers, the population is still critically endangered, mostly because no fish exist outside of Devils Hole. In 2006, the population plummeted to a critical low of just 38 fish.

“Devils Hole was very important in the development of endangered species legislation in the U.S.,” said Bonar. “Our part is to try and understand Devils Hole pupfish behavior, especially spawning and feeding, and the factors that influence those behaviors. Only with this knowledge can we successfully create a backup population and ensure the proper protection of this unique, endangered species.”

Chaudoin observed that after previous disturbances, for example an earthquake in Chile and violent winter rain storms, the fish exhibited higher spawning activity than usual: “They were going crazy the next day.”

Chaudoin and Feuerbacher do not like to speculate but they are intrigued by the idea that disturbance might play an important role in triggering or influencing the fish’s spawning behavior. Chaudoin is investigating this question in a side project.

“There is a possibility they might like disturbance,” she said. “Perhaps the video recordings will reveal something in the aftermath of the April 4 earthquake. I’m going to spend all my nightlife watching hours and hours of video and extracting data from it.”

One of the questions the researchers are hoping to answer is whether natural disturbances, such as earthquakes, are a threat or a boon to the pupfish population.

Powerful Quake Strikes Fiji

Posted by feww on November 9, 2009

Another powerful earthquake strikes Fiji – more intense seismic activity could occur in the region this year

A powerful quake measuring up to 7.3 Mw struck Fiji at 17.212°S, 178.413°E or about 100 km north of the capital, Suva and at a depth of 585 km on Monday, November 09, 2009 at 10:45 UTC.

The mainshock was followed by at least one aftershock measuring 5.3 Mw.

On August 19, 2009 FEWW Moderators posted the following entry:

New Round of Geo-Assualt at Kermadec Trench

Following the powerful 7.8 magnitude earthquake that struck the tip of the Fiordland, South island, New Zealand, followed by a large cluster of aftershocks, another round of geo-assault appears to be gearing up at the southern end of the Kermadec trench.

The Fiordland quakes occurred as a result of a large reverse faulting motion caused by the subduction of the Australian subplate under the Pacific plate, on which Fiordland rests,  in Puysegur Trench, at the Alpine Fault.

The new wave of earthquakes would instead be caused by the ‘mirror image’ action, with Pacific plate subducting beneath the Australian protoplate.

A magnitude 6.3 earthquake that struck south of the Fiji Islands on August 18, 2009 at 21:21 UTC may herald a new round of intense [and unprecedented] seismic activity at Kermadec Trench to the north, NE, and East of the North Island, as well as the north, NE, and east of the South Island, New Zealand.

Powerful quake shakes Sumbawa, Indonesia

Posted by feww on November 8, 2009

M7.0 Earthquake Strikes Sumbawa, Indonesia

Powerful earthquake measuring up to 7.0Mw struck Indonesia’s Sumbawa region, about 77 km east of Tambora volcano and at an estimated  depth of 18 km, November 8, 2009 at 19:41 UTC.

Mount Tambora’s 1815 eruption (Volcanic  Explosivity Index of 7) was the largest in modern history, and perhaps the deadliest of all time, with up to an estimated 100,000 people losing their lives as a result.

Alarmed by its findings concerning the prospect of intense seismic activity in the region, FEWW featured Mt Tambora in its weekly volcano watch VolcanoWatch Weekly  dated 23 July 2009.

See also September 28, 2009 entry:  Up to 3 More Large EQs Could Strike the Pacific Ring of Fire in 2009

FEWW Moderators believe that further, intense seismic activity would most likely occur in the region in the near future.

Oil Spills, Earthquakes and Faults

Posted by feww on October 31, 2009

Oil Spills NO Different to Earthquakes

They Both Spell Disaster, Occur Because of Faults and Happen Regularly in San Francisco Bay

Earthquakes occur in SFB because of geological faults: San Gregorio fault, San Andreas fault, Mt Diablo fault… and Hayward fault. Oil spills occur there as a result of oil companies faults: Arco’s fault, BP’s fault, Chevron’s fault, ConocoPhillips’s fault, Exxon’s fault… and Shell’s fault!

You’d forgiven for thinking there must be an oil spill and an earthquake in the SFBA each day! Because you’d almost be right.

The latest spill, a blackish filthy brown slick of bunker fuel, covered a 250-meter by  4-km stretch of San Francisco Bay on Friday, caused by a “refueling mishap” between an oil tanker, Dubai Star, and a service barge alongside, the U.S. Coast Guard reported.

The slick has not reached land and is in a narrow band because there is little wind and much of it may burn off amid warm weather, giving clean-up crews the upper hand in containing it, Coast Guard Captain Paul Gugg told reporters at a press conference.

“The weather is very cooperative. We’re all over it.” Gugg said.

Gugg said the scope of the contamination does not compare to the massive spill in 2007 of fuel oil from another tanker in the San Francisco Bay that spread across its shores and killed thousand of birds.

However,  Gugg didn’t say how much bunker fuel had spilled into the bay.

The spill comes eight days before the two-year anniversary of the vessel Cosco Busan striking the Bay Bridge in dense fog, ripping open its hull and spilling more than 53,000 gallons of fuel oil that fouled much of the shoreline along the well-known California waterway.

The Busan spill killed more than 2,500 birds and deposited oil on 200 miles of coastline, Pacific Environment was quoted as saying.

Meanwhile,

The unscrupulous oil giant BP has been fined $87 million for failing to remove safety hazards at its massive Texas City refinery, the 3rd largest in the US, where an explosion in 2005 killed 15 workers and injured 180 others.  The Occupational Safety and Health Administration (OSHA) cited 270 violations at the oil refinery, officials said.

In 2005, BP was fined $21.3 million and ordered to repair hazards at their refinery, but it didn’t

“Lawyers acting for victims of the disaster suggested that the renewed action could put BP in breach of a plea agreement two years ago in which it pleaded guilty to a single felony and paid $373m to settle a string of criminal charges.” UK’s Guardian reported.

Powerful Earthquake Strikes Banda Sea

Posted by feww on October 25, 2009

Powerful Quake Measuring up to 7.3 Magnitude Strikes Banda Sea

A powerful earthquake measuring up to 7.3 Mw struck Banda Sea about 40 km WNW of Serua volcano and 65 km south of Manuk volcano, on Saturday, October 24, 2009 at 14:41 UTC.

The quake occurred at 6.161°S, 130.346°E, some 230 km  NNW of Saumlaki, Tanimbar Islands, Indonesia, at a depth of about 140 km. It was followed by a moderate quake measuring up to 5.3 Mw, which struck at 6.749°S, 131.601°E, on Sunday, October 25, 2009 at 00:35:06 UTC.

On February 21, 1938, a large quake measuring M 8.5 struck about 185 km northeast of Saturday’s quake  at a depth of 25km.

FEWW Forecast:

Based on an analysis of seismic activity in the region, FEWW Moderators believe a large earthquake measuring up to M 8.6 could strike Banda Sea in the next 3 – 6 months. Additional events measuring 6.0 to 7.6 Mw could also be expected in the region, anytime.

Strong Earthquake Rattles Hindu Kush, Afghanistan

Posted by feww on October 23, 2009

Strong Quake Measuring as Large as M6.5 Rattles Hindu Kush, Afghanistan

An earthquake measuring as strong as 6.5Mw struck the Hindu Kush region, shaking northern Afghanistan and Pakistan early Friday, local time.

The epicenter was located at 36.471°N, 70.925°E  in the Hindu Kush mountain range about 75 km (50 miles) SSE of Feyzabad, Afghanistan, striking at a depth of about 197 km.

There have been no immediate reports of casualties or structural damage, however, news from the remote mountainous areas may take some time to reach the outside world.. However, frightened locals were reportedly seen escaping into the open areas in Islamabad, Lahore, Peshawar and Rawalpindi and other major cities in the region. A news report said buildings in Kabul (the Afghan capital) shook during the earthquake.
