70% chance of big Tokyo earthquake ‘within 4 yrs’

The Yomiuri Shimbun —  There is a 70 percent probability the Tokyo metropolitan area will be hit directly by a strong earthquake of magnitude-7 level within four years, according to data compiled by a University of Tokyo research team.

The preliminary calculations conducted by a team from the university’s Earthquake Research Institute were based on intensified seismic activity in the area after the Great East Japan Earthquake on March 11.

The findings are more dire than a similar estimate by the central government’s Headquarters for Earthquake Research Promotion, which states there is a 70 percent chance a quake of the same scale will hit the southern Kanto region, including the metropolitan area, within 30 years.

The central government’s Central Disaster Management Council assumes 18 different hypocenters of magnitude-7 level earthquakes, such as in southern Ibaraki Prefecture and the Tachikawa fault zone.

If a magnitude-7.3 earthquake occurs directly under northern Tokyo Bay, as many as 11,000 people are expected to die and about 850,000 buildings to be rendered totally unusable or destroyed by fire.

According to the Meteorological Agency’s observations, after the March 11 disaster, earthquakes of magnitude 3 to 6 occurred an average of 1.48 times a day in the metropolitan area through December. This was about five times the pre-disaster average.

Prof. Naoshi Hirata of the university’s research institute and others based their calculations on the rule of thumb that the frequency of earthquakes is inversely proportional to their strength. For every increase in magnitude of one, the frequency of their occurrence falls by 90 percent.

The metropolitan area was hit by the magnitude-8 level Great Kanto Earthquake in 1923. Five weaker but still serious earthquakes of magnitude-7 level also hit an area extending from southern Ibaraki Prefecture to the Uraga Channel over a period of about 120 years.

The government’s earthquake headquarters obtained its quake estimate data based on the intervals of these quakes in the past. The data did not incorporate the increased seismic activity after the March 11 disaster.

Experts believe seismic activity in the metropolitan area has been intensified by changes in the movements of the Earth’s crust since March 11.

“Intensified seismic activity will continue from several to 10 more years,” Hirata said. “It’s highly probable a strong quake with a magnitude of about 7 will occur during that time.  (Jan. 24, 2012)

Japan Triple Disasters – Update 19 April

Posted by feww on April 19, 2011

Great East Japan Earthquake: 92 percent of the March 11 victims died of drowning

Japan authorities have revealed that 92 percent of the victims of Great East Japan Earthquake, whose bodies have so far been recovered, died of drowning as a result of the deadly tsunami that was spawned by the Mega Quake in the Tohoku region on March 11.

Human Cost of Japan’s March 11 Disasters

  • Death toll: About 14,000
  • No. of Missing: Just over 14,000
  • Main Cause of Death:  About 92% of the victims died of drowning in the tsunami
  • Age Distribution: About two-thirds of the victims were aged 65 or older
  • Source: NHK

Other Stats:

  • No. of Homeless: At least 155,000 [Many others who have moved in with their relatives are NOT included in the govt stats.]
  • Others Missing: In addition to the 14,030 people who are officially missing, an unknown number of others who lived in remote, inaccessible  areas may also have perished, but no records were available as of posting.

Fukushima Nuclear Disaster

Technicians at Fukushima NPP have begun removing highly radioactive water  from basement of Reactor 2 .

Authorities say a total of 70,000 tons of radioactive water is accumulated in the plant’s reactor and turbine buildings, and surrounding trenches.

Remote-controlled robots sent into reactor buildings 1, 2 and 3 on Sunday and Monday showed  radiation levels inside two of the units (1 and 3) were too high for humans.


A remote-controlled robot dubbed “Packbot,” capable of manoeuvring through buildings, taking photos, and measuring radiation levels, is photographed by another Packbot in the stricken Fukushima Daiichi Nuclear Power Plant No.1 reactor building in Fukushima, N. Japan on April 18, 2011. Photo released by Tokyo Electric Power Co. (TEPCO) on April 19, 2011. TEPCO handout photo via Reuters.

Other News

“It was clear even before this disaster and the need to secure funds for reconstruction that to ensure a sustainable fiscal situation, some sort of reform of spending and revenues was necessary,” said Internal Affairs Minister Yoshiro Katayama. “The debate over the fiscal situation is not something that began with this disaster,” he told reporters.

A Japanese restaurant in Auckland, New Zealand has attached bells to its charity donation buckets after a thief stole cash intended for Japan’s earthquake and tsunami victims, a report said. “At least seven donation buckets in Japanese businesses around Auckland have been filched recently.”

Japan nuclear disaster to last nine more months

Posted by feww on April 17, 2011

NEW LEAKS MAY BE RAISING RADIATION in SEA

Nuclear disaster at Fukushima Dai-ichi nuclear power plant may continue for another nine months: TEPCO

Tokyo Electric Power Company, the operator of Japan’s stricken nuclear power plant Fukushima Dai-ichi says it planned to reduce radiation leaks in 3 months and to cool the reactors within another six months, NHK reported. 

“This is the biggest crisis since the founding of our company,” TEPCO Chairman Tsunehisa Katsumata said at a a news conference.

“Getting the nuclear plant under control, and the financial problems associated with that.” He added

“How we can overcome these problems is a difficult matter.”

The conference was broadcast by NHK amid reports that radiation levels in the seawater near Reactor 2 had risen to 6,500 times the legal limit on Friday, about 6 times higher than Thursday’s reading. TEPCO fears that the rise may be due to new leaks.

On April 12, Japanese authorities raised the measure of severity of the Fukushima NPP disaster to the maximum level of 7 on INES. (See below for details.)

The International Nuclear and Radiological Event Scale (INES)

The INES, a logarithmic scale, which was introduced in 1990 by the IAEA to enable prompt communication, classifies the intensity of nuclear incidents as follows:

7 – Major Accident [Chernobyl disaster, criticality accident, April 1986]

6 – Serious Accident [e.g., Kyshtym incident, Mayak, former Soviet Union, steam explosion released up to 80 tons of highly radioactive material into the atmosphere, September 1957. ]

5 – Accident With Wider Consequences [e.g., Three Mile Island accident  Pen State, U.S., partial meltdown release radioactive gases  into the environment, March 1979.]

4 – Accident With Local Consequences [e.g., Sellafield, UK, at least 5 incidents reported between 1955 to 1979]

3 – Serious Incident [e.g., Vandellos NPP, Spain, fire destroyed control systems; the reactor was shut down, July1989]

2 – Incident [e.g., Forsmark NPP, Sweden, a backup generator failed, July 2006]

1 – Anomaly [e.g., TNPC, France, 1,600 gallons of water containing 75 kilograms (170 lb) of uranium leaked into the environment,  July 2008]

0 – Deviation (No Safety Significance) [e.g., Atucha, Argentina – Reactor shutdown caused by tritium increase in reactor encasement, December 2006.]

Japan Nuclear Disaster Update

Japanese authorities have finally raised the measure of severity of the Fukushima NPP disaster to the maximum level of 7 on INES, officials said in an NHK telecast.

Japanese government’s Nuclear Safety Commission had earlier revealed that the amount of radioactive iodine 131 released from Fukushima NPP had reached 10,000 terabecquerels per hour, for several hours at one stage, a level that prompted classification of the breach as a Major Accident [level 7 on INES, e.g, Chernobyl disaster, criticality accident, April 1986, see below,] Kyodo news reported.

The radiation level has subsequently fallen  to about one terabecquerel per hour, a report said.

“We have upgraded the severity level to seven as the impact of radiation leaks has been widespread from the air, vegetables, tap water and the ocean,” said a spokesman for Japan’s Nuclear and Industrial Safety Agency (NISA).

Radiation leaks from the stricken nuclear plant have not stopped completely and could exceed the  Chernobyl release 25 years ago, an TEPCO official said, NHK reported.

M6.3 Quake Strikes 77km ESE Tokyo

Posted by feww on April 12, 2011

YOU HAVE BEEN WARNED: JPTRMT1

JAPAN MUST DECOMMISSION ALL NUCLEAR POWER PLANTS NOW !

Strong Earthquake Strikes Near the East Coast of Honshu, Japan

The 6.3Mw quake,which occurred at 08:08 JST (Monday, April 11, 2011 at 23:08 UTC), was epicentered at 35.4ºN, 141.0ºE and struck at a depth of about 30km, Japan Meteorological Agency (JMA) said.

The quake reportedly swayed buildings in Tokyo and shut down runways at Narita international airport.

Yesterday’s 7.1Mw quake killed at least 1 person and knock out power to about a quarter of a million households, Japanese authorities reported earlier.

Japan Nuclear Disaster

Meanwhile, Tokyo Electric power Company (TEPCO) announced that its technicians  were fighting a fire near Reactor 4 at the stricken Fukushima NPP earlier today, amid reports that the country was raising its nuclear disaster alert to the maximum level.

Japanese government’s Nuclear Safety Commission has now revealed that the amount of radioactive iodine 131 released from Fukushima NPP had reached 10,000 terabecquerels per hour, for several hours at one stage, a level that classifies the breach as a Major Accident [level 7 on INES, e.g, Chernobyl disaster, criticality accident, April 1986, see below,] Kyodo news reported.

Iodine 131 is believed to have caused the high incidence of thyroid cancer among children living near the Chernobyl plant when the 1986 nuclear disaster occurred.

Will the Scope of Fukushima Nuclear Disaster Widen?

Posted on April 6, 2011 UPDATED at 13:00UTC

Based on the information available, FIRE-EARTH believes there’s a strong probability that the extent of Fukushima nuclear disaster could widen to directly impact large population centers in Japan up to a 250 – 300km radius of the plant, which includes Tokyo Metropolitan Area.

The reactor vessel or sections of its attachments in one or more of the severely damaged reactors at the plant could explode releasing humongous amounts of radiation into the environment [Probability ≥66% as of posting,] dwarfing the Chernobyl disaster by a massive factor.

What is a lethal dose of radiation from a single Exposure?

Studies of the 1945 atomic bombing at Hiroshima and Nagasaki show that 100 percent of victims whose bodies were exposed to 600,000 millirems (6,000 mSv) died from radiation. About 50 percent of victims who received  450,000 millirems (4,500 mSv) of radiation also died.

(Note: Rem is a unit of ionizing radiation equal to the amount that produces the same damage to humans as one roentgen of high-voltage x-rays.  Source: MIT)

1 rem = 10 mSv  (1 Sv = 100 rem)

Background Radiation in millirems per year (mrem/yr)

  • Average background radiation (US):  300
  • Higher altitudes (e.g, Denver): 400

“Safe Levels” of Radiation (U.S.)

Limits above natural background radiation levels (average 300 millirems per year) and medical radiation:

  • Occupation Limit: Maximum of 5,000  (the limit for a worker using radiation)
  • Average Natural Background: 300

[Note: Lifetime cumulative exposure should be limited to a person’s age multiplied by 1,000 millirems, e.g., a 70-year-old person, 70,000 millirems.]

Adults

  • Max single dose for an adult: 3,000
  • Annual total dose: 5,000

Under 18

  • Max single dose for a person aged under 18 years: 300 millirems (whole body equivalent)
  • Annual total exposure: 500

Fetal Exposure

  • Maximum limit for fetal exposure during gestation period:  50 millirems per month above background levels

Medical

  • Single Chest X-ray (the whole body equivalent): 2 millirem

Air Travel

  • Coast-to-coast US round trip flight: 12 millirems

*Note:  Radiation dose of about 2,000 millisieverts (200,000 millirems) cause serious illness.

Half-life of some radioactive elements

[NOTE: Half-life is the time taken for a radioactive substance to decay by half.]

  • Cesium-134 ~ 2  years
  • Cesium-137 ~ 30 years
  • Iodine-131 ~ 8 days
  • Plutonium-239 ~ 24,200 years
  • Ruthenium-103 ~ 39 days [Ruthenium is a fission product of uranium-235.]
  • Ruthenium-106 ~ 374 days
  • Strontium-90 ~ 28.85 years  [Strontium-90 is a product of nuclear fission and is found in large amounts in spent nuclear fuel and in radioactive waste from nuclear reactors.]
  • Uranium-234 ~  246,000 years
  • Uranium-235 ~ 703.8  million years
  • Uranium-238  ~ 4.468 billion years

YOU HAVE BEEN WARNED: JPTRMT1

Powerful Quake Strikes Eastern Honshu on One-Month Anniversary of  Great East Japan Earthquake

JAPAN MUST DECOMMISSION ITS NUCLEAR POWER PLANTS NOW !

The quake measuring 7.1Mw struck at a depth of 10km about 160 km NNE of Tokyo, and 37km W of Iwaki city in Fukushima prefecture.

The powerful quake shook buildings in Tokyo and a large area of eastern Honshu, Japan’s main island.

Fukushima Nuclear Disaster

The powerful quake, which was followed by a tsunami warning, forced technicians to flee the stricken Fukushima Dai-ichi NPP. The latest shock struck amid reports that Japanese authorities were considering to extend the evacuation zone around NPP because of “prolonged exposure to radiation” in several areas.

The villages and towns outside the 20 km evacuation zone that have accumulated radiation will be evacuated, Chief Cabinet Secretary Yukio Edano Edano said at a daily news conference.

The decision to enlarge the evacuation zone around the Fukushima plant is “based on data analysis of accumulated radiation exposure information,” he said.

“These new evacuation plans are meant to ensure safety against risks of living there for half a year or one year,” he said, adding that there was no need for immediate evacuations.

Japan’s Triple Disaster: Human Cost

  • Official Death Toll: 13,127
  • Missing:  14,348
  • Homeless: At least 155,000
  • Others: In addition to the above, an unknown number of people in remote areas may have perished, but no records are available as of posting.

Global Tectonics Alert – April 9

Posted by feww on April 9, 2011

JPTRMT1

This is an amendment to an earlier release dated April 8, 2011

Japan Earthquake Forecast

FIRE-EARTH estimates that about 80 exajoules (EJ) of tectonic stress energy could be accumulated in Japan Region between now and early 2016.

Most of the energy is forecast to be released as large earthquakes including a massive shock, a Megathrust earthquake, the largest on record, measuring 10.0+Mw releasing about 64EJ of energy.

[NOTE: The 1960 Valdivia earthquake (The Great Chilean Earthquake) is the largest ever earthquake recorded measuring 9.5Mw. The quake struck on May 22, 1960 at 38.29ºS, 73.0ºW. Seismic moment release: ~ 11.3 EJ]

Japan Trench Mega Thrust Earthquake No. 1 (JPTRMT1)  could break up the Honshu island into some half dozen fragments and scores of smaller splinters. [An impression depicting the new geography of the islands may be posted later.]

The Megashock could trigger a colossal tsunami completely submerging coastal areas around the Pacific Ocean, and traveling many miles inland.

JPTRMT1 could trigger multiple volcanic eruptions throughout Japan Region and rest of the western half of the PRF, as far away as in Alaska, the Philippines, Indonesia, PNG, Fiji, Tonga, New Zealand and rest of the South Pacific region. [Groups J, H, K and L on the map below.

The 10.0+Mw Megashock, its massive aftershocks, the spawned mountainous tsunamis and the multiple volcanic eruptions would cause  death and destruction on unprecedented scales throughout the Pacific Rim countries and beyond.

The impact of the volcanic eruptions would affect the entire world, resulting in severe climatic episodes, major losses of crops, famine and exacerbate mass dieoffs, which may have already started as a result of drought and deluge and other collapse mechanisms.

Forecast Details

  • Name Assigned by FIRE-EARTH: Japan Trench Mega Thrust Earthquake No. 1 (JPTRMT1)
  • Location: Near the East Coast of Honshu, Japan
  • Depth: ~ 26km
  • Magnitude: 10.0+Mw
  • Energy released: ~ 64EJ
  • Largest Aftershocks:  ~ 9.0 Mw
  • JPTRMT1 and its Massive aftershocks would trigger dozens of colossal super tsunamis.
  • The unprecedented super seismic episode could trigger between 40 and 80 volcanoes to erupt simultaneously, shortly after the mainshock strikes.
  • Millions of people could perish within the first few hours, and hundreds of millions more left without clean water, food, or shelter, as a result of the events.

Alaska Update [15:00UTC]

Fukushima Nuclear Disaster Update – March 30

Posted by feww on March 30, 2011

Radiation Rises in Seawater near Fukushima NPP

Radioactive iodine was detected at 3,355 times the legal limit in seawater some 330 meters south of Japan doomed Fukushima Daiichi nuclear plant, said Japan’s nuclear safety agency.

Iodine 131 is believed to have caused the high incidence of thyroid cancer among children living near the Chernobyl plant when the 1986 nuclear disaster occurred.

Highly radioactive water has inundated at least 3 reactor buildings and is also  found elsewhere at the stricken nuclear plant.

Half-life of some radioactive elements

[NOTE: Half-life is the time taken for a radioactive substance to decay by half.]

  • Cesium-134 ~ 2  years
  • Cesium-137 ~ 30 years
  • Iodine-131 ~ 8 days
  • Plutonium-239 ~ 24,200 years
  • Ruthenium-103 ~ 39 days [Ruthenium is a fission product of uranium-235.]
  • Ruthenium-106 ~ 374 days
  • Strontium-90 ~ 28.85 years  [Strontium-90 is a product of nuclear fission and is found in large amounts in spent nuclear fuel and in radioactive waste from nuclear reactors.]
  • Uranium-234 ~  246,000 years
  • Uranium-235 ~ 703.8  million years
  • Uranium-238  ~ 4.468 billion years

TEPCO UPDATE

The most ridiculous news out of Tokyo Electric Power Company (TEPCO): Chairman Tsunehisa Katsumata has told reporters that he thinks Fukushima Reactors 1 to 4 MAY HAVE TO BE SHUT DOWN PERMANENTLY!

[REALLY?]

Also, is he implying that Reactor 5 and 6, or any part of the Fukushima Dai-ichi for that matter, are still safe?

Death Toll

The number of people dead or missing from the megaquake and tsunami on March 11 stands at about 28,000 people.

Aftershock

Meanwhile another strong aftershock measuring 6.0Mw struck off the east coast of Honshu about 246 km (152 miles) ENE of Tokyo, USGS/EHP reported.

Japan Meteorological Agency (JMA) had not reported this quake, as of posting.

The magnitude 9.0 megaquake that struck northeastern Honshu, Japan on March 11, 2011, spawned a deadly tsunami which inundated vast coastal areas along the eastern seaboard of the country’s main island. Top image shows flooded croplands and settlements along the Kitakami River, which was taken by ASTER on NASA’s Terra satellite on March 14, 2011.

Megaquake and Tsunami, Nuclear Power Plant Crisis  -UPDATE (17 March 2011, at 05:00 UTC)

The confirmed death toll from Friday’s 9.0Mw megaquake and  tsunami has climbed to 5,178, police said. At least 8,606 people are still missing.

The US state department has advised the US citizens living within 80km of Fukushima Daiichi NPP to leave the area. Japanese government’s exclusion zone is 20km, with a 20-30km caution zone.

Intelligent People and Nuclear Power Plants

The governor of Fukushima prefecture, where the doomed  nuclear plant is located, has complained that the NPP evacuees lack basic necessities, including sufficient hot food, warm clothes  and water, reports say.

As of Sunday March 13, about 230,000 people had been evacuated from the vicinity of the badly damaged nuclear plants, according to a government report.

More Serious Than Reported

TheUS Nuclear Regulatory Commission chairman, Greg Jaczko, has told a congressional energy and commerce subcommittee hearing in Washington that problems with attempts to cool the troubled reactors are more serious than reported.

“We believe that around the reactor site there are high levels of radiation.”

“[It’s] very difficult for emergency workers to get near the reactors. The doses they could experience would potentially be lethal doses in a very short period of time” he told the US lawmakers.

Three Mile Island

Meanwhile, the US Energy Secretary said the situation seemed to be more serious than the 1979 partial meltdown of the Three Mile Island NNP in Pennsylvania.

According to nuke scientists in France, the Three Mile Island partial meltdown was a 5 on a scale of 1 to 7, with the Chernobyl core meltdown scoring 7, and the Fukushima NPP crisis so far rating 6 in severity.

FIRE-EARTH Forecasts: Japan Earthquakes

Posted by feww on March 13, 2011

Japan Earthquakes: A Summary of Forecasts by FIRE-EARTH Blog

A number of colleagues and some of our readers have asked for a summary of the earthquake forecasts for Japan that were made by this blog.

1. On May 18, 2009 FIRE-EARTH said:

Earthquake Forecast: Tokyo, Japan

A powerful earthquake could strike near south coast of Honshu in late June – September 2009

FEWW Forecast: A magnitude 7.8+ quake could strike the Tokyo Bay area in the next 30-90 days.

Details of Forecast

Magnitude: 7.8 or larger
Estimated Date:  June 14, 2009 [Uncertainty T+ 60 days]
Epicenter: 35.56°N,  139.98ºE
Location: Tokyo Bay, Tokyo, Japan
Depth: 8km [Uncertainty: +/- 2.4km]
Distances:

  • 8 km south of Tokyo Disneyland
  • 12 km SE of Imperial Palace
  • 14 km WSW of Chiba City
  • 19 km NE of Yokohama

Horizontal Uncertainty: +/- 3.8 km
Probability of Occurrence: 0.8

2. Between 9 – 12  August 2009, within the 60-day uncertainty time period stated in the forecast, 3 strong to powerful shocks struck Japan Region redistributing the earthquake stress energy and affecting the FIRE-EARTH Tokyo EQ Forecast:

3rd Powerful Quake in 3 Days Strikes Japan Region

1. A powerful earthquake measuring 7.1Mw struck about 165km W of Hachijo-jima, Izu Islands, Japan, at a depth of 303.1km at on August 9, 2009 at 10:55:56 UTC. [EQ No 1 on the location map below.]

2. A strong earthquake measuring 6.4 occurred about 30km SSW of Shizuoka, Japan, at a depth of 30km at 20:07:07 UTC on Monday, August 10, 2009. [No 2 on the location map below.]

3. A 3rd earthquake [this report] measuring 6.7 occurred about 60km ESE of Hachijo-jima, Izu Islands, Japan region at a depth of 51 km at 22:48:51 UTC on August 12, 2009. [No 3 on the location map below.]

3.  On August 17, 2009 after a 4th strong quake had struck Japan Region, having analyzed the new data, FIRE-EARTH forecast that as many as 10 additional magnitude 6+ quakes could yet strike the region [before a catastrophic event occurs.]

4th Powerful Quake Strikes Japan Region

Posted by feww on August 17, 2009

Magnitude 6.8 Quake Strikes Ryukyu Islands, Japan

FEWW Moderators had predicted more powerful earthquakes in the region last week, and now believe as many as 10 additional magnitude 6+ quakes could yet strike the region in coming weeks

Volcanic Activity Forecast

FEWW Moderators also believe there is a strong probability (0.8+) that the submarine Unnamed Volcano located East of Taiwan at 24.00N, 121.83E could erupt in 2009. [See previous comment.]

4. See  below for a list of the shocks forecasted.

5. List of the Latest Forecasts

JAPAN’s Sendai Quake Aftershocks

At least 25 aftershocks have been reported by Japan’s Meteorological Agency (JMA) since yesterday’s powerful 7.2Mw quake which struck off the coast of Miyagi Prefecture, about 168km east of the city of Sendai.

Two of the largest shocks measured M6.1 and 6.8, striking Sanriku Oki region at 03:45 JST [03:51 JST 10 Mar 2011] and 06:24 JST  [06:29 JST 10 Mar 2011] respectively.

FIRE-EARTH forecasts intense seismic activity in Japan Region during the 2011 – 2015 period.

Further deatails would be released on the need-to-know basis, partly to prevent Internet prophets from cashing in on FIRE-EARTH forecasts.

FEWW Forecast

More powerful earthquakes, some related to this event, could strike Japan Region, much closer to the coastal areas.

On June 13, 2010, FIRE-EARTH forecast

Fire Earth Model shows that Japan region could be struck by up to 4 additional strong to large earthquakes possibly this year/early next year, one of which could be a catastrophic event.

Fire-Earth Quake Forecast: Japan Earthquakes

Japan region could be struck by up to 3 additional strong to large earthquakes by end 2010/early 2011, one of which could be a catastrophic event.

Waves of Intense Seismic Activity Could Strike Eastern Honshu, Japan

The earthquakes could affect a wide region within 100 to 150 km radius of Tokyo Bay area.

FIRE-EARTH forecasts intense seismic activity in Japan Region during the 2011 – 2015 period.

Further deatails would be released on the need-to-know basis, partly to prevent Internet prophets from cashing in on FIRE-EARTH forecasts.

6. NEW FORECAST: As Many as 4 Large Earthquakes Could  Strike Japan Region by 2015

This quake may be a foreshock, with a larger event yet to follow: FIRE-EARTH

7. In 2011 Much More Disastrous

Posted by feww on September 13, 2010, FEWW warned:

2011 SIX TIMES MORE DISASTROUS THAN 2010

Global Disasters in 2011 Could Impact 1/3 to 1/2 of the Human Population

The impact of anthropogenic and human-enhanced natural disasters on the population will be 600 percent more severe in 2011 compared with 2010: Fire-Earth Forecast

Earth is critically wounded and diseased as a result of human assault and battery.

Humans’ first wave of serious [near-fatal] assault on the planet began in the early 1980s and has since heightened in severity.

Our feverish planet‘s fight against the pathogens is entering a critical phase. The earth’s defense mechanism is employing geophysical  phenomenon, as a result of which the impact of natural disasters on human population is intensifying.

In 2007 EDRO models showed that the intensity of disasters caused as a result of the planet’s self-healing process would lead to the first wave of collapse of the population centers, globally by about 2012.

It has!

The collapse has already started and would ultimately lead to the extinction [possibly the near-extinction] of human race.

For the EDRO forecast to be true, the final years leading to the start of collapse, namely 2010, 2011 and 2012, must necessarily be progressively more disastrous.

Based on its models, Fire-Earth Moderators forecast in late December 2009 that 2010 would prove to be the most disastrous year on record. And with more than 100 days left to the end of this year, the forecast has already proven to be true and accurate.

What about 2011?

Fire-Earth models show that the impact of anthropogenic and human-enhanced natural disasters would be about 600 percent more severe in 2011 compared with this year.

Based on our findings, we estimate that between one-third and one-half of the world population could be affected in some way by various disasters that are forecast to occur in 2011.

JAPAN’s Sendai Quake Aftershocks

At least 25 aftershocks have been reported by Japan’s Meteorological Agency (JMA) since yesterday’s powerful 7.2Mw quake which struck off the coast of Miyagi Prefecture, about 168km east of the city of Sendai.

Two of the largest shocks measured M6.1 and 6.8, striking Sanriku Oki region at 03:45 JST [03:51 JST 10 Mar 2011] and 06:24 JST  [06:29 JST 10 Mar 2011] respectively.

FIRE-EARTH forecasts intense seismic activity in Japan Region during the 2011 – 2015 period.

Further deatails would be released on the need-to-know basis, partly to prevent Internet prophets from cashing in on FIRE-EARTH forecasts.

Tsunami Observations
As of 05:40 JST (UTC+ 9 hours)
At some parts of the coasts, tsunamis may be higher than those observed at the observation sites.
The tsunamis can become higher from now on.

However, JMA later downgraded the warning to a tsunami advisory for the area.
