Japan historik earthquakes tsunami and volcanoes :

The Japanese archipelago is located in an area where several continental and oceanic plates meet. This is the cause of frequent earthquakes and the presence of many volcanoes and hot springs across Japan. If earthquakes occur below or close to the ocean, they may trigger tidal waves (tsunami).
Historic earthquakes
Many parts of the country have experienced devastating earthquakes and tidal waves in the past. The Great Kanto Earthquake, the worst in Japanese history, hit the Kanto plain around Tokyo in 1923 and resulted in the deaths of over 100,000 people.
In January 1995 a strong earthquake hit the city of Kobe and surroundings. Known as the Southern Hyogo Earthquake or Great Hanshin Earthquake, it killed 6,000 and injured 415,000 people. 100,000 homes were completely destroyed and 185,000 were severely damaged.
Earthquake measurement
The Japanese "shindo" scale for measuring earthquakes is more commonly used in Japan than the Richter scale to describe earthquakes. Shindo refers to the intensity of an earthquake at a given location, i.e. what people actually feel at a given location, while the Richter scale measures the magnitude of an earthquake, i.e. the energy an earthquake releases at the epicenter.
The shindo scale ranges from shindo one, a slight earthquake felt only by people who are not moving, to shindo seven, a severe earthquake. Shindo two to four are still minor earthquakes that do not cause damage, while objects start to fall at shindo five, and heavier damage occurs at shindo six and seven.
During and after an earthquake
Falling objects, toppling furniture and panic present the greatest dangers during an earthquake. Try to protect yourself under a table or doorway. Do not run outside, and try to remain as calm as possible. If you are in the streets, try to find protection from glass and other objects that may fall from surrounding buildings.
After a strong earthquake, turn off ovens, stoves and the main gas valve. Then listen to the radio or television for news. In coastal areas beware of possible tidal waves (tsunami) while in mountainous areas beware of possible land slides.
Japan is one of the most seismically active countries in the world, with 108 active volcanoes, according to National Geographic. Japan rests on the Ring of Fire, which is "a series of volcanoes and fault lines that roughly circle the Pacific Ocean."
The United States has seen some activity underground recently as well. In Seattle, Wash., a magnitude 4.5 earthquake shook the area, but no damage was reported. Alaska, meanwhile, is paying attention to its Mount Redoubt volcano, which is showing signs of a possible eruption.
Scientific American wrote, "The so-called ring of fire edging the Pacific is known to be highly active. So it's no surprise that said ring is jolting Seattle residents awake and putting denizens of Anchorage on notice of an imminent eruption from the redoubtable Mount Redoubt."

FUKUSHIMA:The world bank report

The World Bank said in report Monday that Japan may need five years to rebuild from the catastrophic disasters, which caused up to $235 billion in damage, saying the cost to private insurers will be up to $33 billion and that the government will spend $12 billion on reconstruction in the current national budget and much more later.
 The toll of Japan’s triple disaster came into clearer focus Monday after police estimates showed more than 18,000 people died, the World Bank said rebuilding may cost $235 billion and more cases of radiation-tainted vegetables and tap water turned up.
Japanese officials reported progress over the weekend in their battle to gain control over a nuclear complex that began leaking radiation after suffering quake and tsunami damage, though the crisis was far from over, with a dangerous new surge in pressure reported in one of the plant’s six reactors.
The announcement by Japan’s Health Ministry late Sunday that tests had detected excess amounts of radioactive elements on canola and chrysanthemum greens marked a low moment in a day that had been peppered with bits of positive news: First, a teenager and his grandmother were found alive nine days after being trapped in their earthquake-shattered home. Then, the operator of the overheated nuclear plant said two of the six reactor units were safely cooled down.
The safety of food and water was of particular concern. The government halted shipments of spinach from one area and raw milk from another near the nuclear plant after tests found iodine exceeded safety limits. Tokyo’s tap water, where iodine turned up Friday, now has cesium. Rain and dust are also tainted.
Early Monday , the Health Ministry advised Iitate, a village of 6,000 people about 30 kilometers northwest of the Fukushima plant, not to drink tap water due to elevated levels of iodine. Ministry spokesman Takayuki Matsuda said iodine three times the normal level was detected there — about one twenty-sixth of the level of a chest X-ray in one liter of water.
In all cases, the government said the radiation levels were too small to pose an immediate health risk.
All six of the nuclear complex’s reactor units saw trouble after the disasters knocked out cooling systems. In a small advance, the plant’s operator declared Units 5 and 6 — the least troublesome — under control after their nuclear fuel storage pools cooled to safe levels. Progress was made to reconnect two other units to the electric grid and in pumping seawater to cool another reactor and replenish it and a sixth reactor’s storage pools.
Police in other parts of the disaster area declined to provide estimates, but confirmed about 3,400 deaths. Nationwide, official figures show the disasters killing more than 8,600 people, and leaving more than 13,200 people missing, but those two lists may have some overlap.
TOKYO:
 The official death toll from Japan’s devastating earthquake and tsunami has risen to 8,133 with 12,272 still missing.
Police earlier said they feared more than 15,000 people had died in one prefecture alone, Miyagi, in the March 11 disaster.
Some of the missing may have been out of the region at the time of the disaster. In addition, the massive power of the tsunami likely sucked many people out to sea. If the 2004 Indian Ocean tsunami is any guide, most of those bodies will not be found.

Japan's nuclear crisis escalates further

 SENDAI: Japan's nuclear crisis escalated Tuesday as two more blasts and a fire rocked a quake-stricken atomic power plant, sending radiation up to dangerous levels.
Radiation around the Fukushima No.1 plant on the eastern coast had "risen considerably", Prime Minister Naoto Kan said, and his chief spokesman announced the level was now high enough to endanger human health.
In Tokyo, some 250 kilometres (155 miles) to the southwest, authorities also said that higher than normal radiation levels had been detected in the capital, the world's biggest urban area, but not at harmful levels.
Kan warned people living up to 10 kilometres (six miles) beyond a 20 km (12-mile) exclusion zone around the nuclear plant to stay indoors.
The fire, which was later reportedly extinguished, was burning in the plant's number-four reactor, he said, meaning that four out of six reactors at the facility are now in trouble.
The official death toll has risen to 2,414, police said Tuesday, but officials say at least 10,000 are likely to have perished.
The crisis at the ageing Fukushima plant has escalated daily after Friday's quake and tsunami which knocked out cooling systems.
On Saturday an explosion blew apart the building surrounding the plant's number-one reactor. On Monday, a blast hit the number-three reactor, injuring 11 people and sending plumes of smoke billowing into the sky.
Early on Tuesday a blast hit the number-two reactor. That was followed shortly after by a hydrogen explosion which started a fire at the number-four reactor.
Hashimoto said supermarkets are open but shelves are completely empty. "Many children are sick in this cold weather but pharmacies are closed. Emergency relief goods have not reached evacuation centres in the city.
Everyone is anxious and wants to get out of town. But there is no more petrol. We are afraid of using a car as we may run out of petrol."
The UN's nuclear watchdog, the International Atomic Energy Agency, said Tokyo had asked for expert assistance in the aftermath of the quake which US seismologists are now measuring at 9.0-magnitude, revised up from 8.9.
But the IAEA's Japanese chief Yukiya Amano moved to calm global fears that the situation could escalate to rival the world's worst nuclear crisis at Chernobyl in the Ukraine in 1986.
Officials have already evacuated 210,000 people in the exclusion zone around the crippled plant.
At one shelter, a young woman holding her baby told public broadcaster NHK: "I didn't want this baby to be exposed to radiation. I wanted to avoid that, no matter what."
Further north in the region of Miyagi, which took the full brunt of Friday's terrifying wall of water, rescue teams searching through the shattered debris of towns and villages have found 2,000 bodies.
And the Miyagi police chief has said he is certain more than 10,000 people perished in his prefecture.
Millions have been left without water, electricity, fuel or enough food and hundreds of thousands more are homeless and facing harsh conditions with sub-zero temperatures overnight, and snow and rain forecast.
Tokyo stocks, which were punished Monday when the markets reopened, sending indexes around the world sliding, plummeted another 12 percent by early afternoon on Tuesday.
Leading risk analysis firm AIR Worldwide said the quake alone would exact an economic toll estimated at between $14.5 billion and $34.6 billion (10 billion to 25 billion euros) -- even leaving aside the effects of the tsunami.

Japan:Tokyo,Osaka earthquake,tsunami update

TOKYO: Japan instructed local authorities to start screening food for radioactivity after accidents at an earthquake-hit nuclear power plant sparked fears of wider contamination.
It is the first time Japan has set radiation limits on domestically produced food, a health ministry official said.
The limits are in line with an anti-disaster programme prepared in advance by the government's atomic power safety commission, said the official.
Limits vary depending on the type of foodstuff but have been set in consultation with internationally accepted levels and average intake in the Japanese diet.
Radioactivity leaked into the air after explosions at the Fukushima No.1 plant, where last week's quake and tsunami knocked out the reactor cooling systems.
Several Asian nations have said they will screen food imported from Japan for radiation while the European Union has called for similar checks.

OSAKA:

A 5.9 magnitude earthquake rattled Japan’s Ibaraki Prefecture south of the stricken Fukushima No. 1 nuclear plant on Saturday, the US Geological Survey said, but no tsunami warning was issued.
The USGS said the quake struck at 6.56 pm (0956 GMT) and was centred 98 kilometres (61 miles) south of Fukushima and 142 kilometres from Tokyo.
The quake shook buildings in Tokyo, but no damage was immediately reported, public broadcaster NHK said, adding that flights at the capital’s Narita Airport were briefly suspended for safety checks before resuming.
The quake struck at a depth of 24.7 kilometres (15.3 miles).
Japan’s meteorological agency measured the quake at a magnitude of 6.1.

TOKYO:

 The number of people confirmed as dead or listed as missing by Japan’s national police agency topped 18,000 on Saturday, eight days after the massive earthquake and tsunami struck.
Hopes of finding many more survivors amid the rubble have diminished amid a cold snap that has hit Japan’s northeast, covering much of the disaster area in snow earlier this week.
The death toll has surpassed that of the 7.2-magnitude quake that struck the western Japanese port city of Kobe in 1995, killing 6,434 people.
The March 11 quake is now Japan’s deadliest natural disaster since the 1923 Great Kanto Earthquake, which killed more than 142,000 people.
The latest police figures for people missing do not include local reports from along the tsunami-hit coast of vast numbers of people unaccounted for.
The mayor of the coastal town of Ishinomaki in Miyagi prefecture said Wednesday that the number of missing there was likely to hit 10,000, Kyodo News reported.
On Saturday, public broadcaster NHK said that around 10,000 people were unaccounted for in the port town of Minamisanriku in the same prefecture.

 

POWERFULL EARTH QUAKE AND TSUNAMI JAPAN

TOKYO: A massive 8.9 magnitude quake hit northeast Japan on Friday, causing many injuries, fires and a four-metre (13-ft) tsunami along parts of the country's coastline.
There were several strong aftershocks and a warning of a 10-metre tsunami following the quake, which also caused buildings to shake violently in the capital Tokyo.
Public broadcaster NHK showed flames and black smoke billowing from a building in Odaiba, a Tokyo suburb, and bullet trains to the north of the country were halted.
Black smoke was also pouring out of an industrial area in Yokohama's Isogo area.  An overpass, location unknown, appeared to have collapsed into the water.
Passengers on a subway line in Tokyo screamed and grabbed other passengers' hands. The shaking was so bad it was hard to stand.
Hundreds of office workers and shoppers spilled into Hitotsugi street, a shopping street in Akasaka in downtown Tokyo.
Household goods ranging from toilet paper to clingfilm were flung into the street from outdoor shelves in front of a drugstore.
Crowds gathered in front of televisions in a shop next to the drugstore for details. After the shaking from the first quake subsided.
The U.S. Geological Survey earlier verified a magnitude of 7.9 at a depth of 15.1 miles and located the quake 81 miles east of Sendai, on the main island of Honshu. It later upgraded it to 8.8.
A police car drove down Hitotsugi Street, lights flashing, announcing through a bullhorn that there was still a danger of shaking.
The Tokyo stock market extended its losses after the quake was announced. The central bank said it would do everything to ensure financial stability.
Japan's northeast Pacific coast, called Sanriku, has suffered from quakes and tsunamis in the past and a 7.2 quake struck on Wednesday. In 1933, a magnitude 8.1 quake in the area killed more than 3,000 people. Last year fishing facilities were damaged after by a tsunami caused by a strong tremor in Chile.
Earthquakes are common in Japan, one of the world's most seismically active areas. The country accounts for about 20 percent of the world's earthquakes of magnitude 6 or greater.
Meanwhile, officials of fishermen's unions in Iwate and Miyagi prefectures said they began conducting on-the-spot examinations to check the extent of damage inflicted by the Wednesday quake on their members' farming facilities like those for oysters and scallops.
The Thursday morning quake brought the number of quakes felt in Japan since Wednesday to more than 30.

FLOOD WARNING AND FORECAST ALERT REPORT PAKISTAN 2010

FLOOD FORECAST (ALERT )FOR   SUTLEJ  RIVER

According to present Hydro-Meteorological situation & rains observed in the upper catchment areas of River Sutlej, Ganda Singh Wala (Kasur District) may attain a LOW FLOOD level during the period from 1200 PST of  26th  September-2010 to 1800 PST of 27th September-2010  ranging between 50,000 to 60,000 cusecs (Approximately Gauge 18 – 19 feet ).
This may create inundation in low lying areas of river Sutlej. The inhabitants in the river bed around the districts of Kasur, Okara and Pakpattan may affect. It is requested that concerned authorities may take precautionary measures to warn the people residing in the river bed.
SIGNIFICANT FLOOD FORECAST FOR RIVER INDUS AT KOTRI

According to prevailing hydrological conditions the 2nd Flood wave is passing from Kotri and River is maintaining Exceptionally High Flood level with inflow of 964897 Cusecs. It may further rise during next 36-hours. The sustained peak at Kotri may last for next 2 to 3 days. Thereafter it may start falling and is likely to remain between 7,00,000 to 9,00,000 Cusecs during subsequent 7 to 9 days and around 6,00,000 Cusecs for  subsequent one week.
Under this scenario, the inundation and riverine Flooding is expected at low lying areas of Sajawal, MirpurBataro, MirpurSakro, JhangShahi, AllahRakhio, ShadadKot , Jamshoro, Matiari, Makaro, Ketibander, Shahbander in  Thatta and Hyderabad  Districts  along with the river bed.
All concerned authorities are requested to take precautionary measures to avoid loss of human lives and property. 

Flood Alert for Sutlej  Ravi and Chenab Rivers
       
Sutlej River
 According to Indus Water Treaty, India shall inform Pakistan when the release of water from Ferozepur down stream increases to 50,000 Cusecs or more. India has not yet informed Pakistan regarding the release of such quantity of water from Ferozepur. The slight rise in water at Ganda Singh Wala is only due to rains in the lower catchments of Sutlej below Bhakra dam. As such the water in Sutlej is likely to remain around 50,000 Cusecs in next 2-days.
                                                                            

River Ravi
 The rains in the area below Madhopur headworks and in the Catchment of Nullahs of River Ravi (Deg, Bein, Kethar, Ujh, Basanter) have caused a slight increase in the inflow at Jassar and Shahdara. However, the situation is not dangerous. According to Indus Treaty, India shall inform Pakistan when they release the water from Madhopur headworks more than 30,000 Cusecs and they have not yet informed. Therefore it is presumed that the flow in River Ravi shall remain below low flood level i.e. 40,000 Cusecs.


River Chenab
 The prevailing metrological conditions suggest that the chances of heavy rains in the Catchments of river Chenab are minimum during next 2-days. Therefore there is no imminent danger of any flood in river Chenab. However some rain may cause slightly increased flow in river Chenab, which may not be taken as dangerous situation. The flow shall remain at low flood level (around 1,00,000 Cusecs)
According to prevailing hydrological conditions the Flood wave is passing from Kotri and River has attained Exceptionally High Flood level at Kotri with inflow 8,37,982 Cusecs at 1200 PST. It will continue rising and is likely to attain Flood level ranging between 8,50,000 to 9,00,000 Cusecs during next 24-hours. The River Indus at Kotri shall maintain and sustain peak, which is expected to last 4 to 5 days.
Inflow between 7,00,000 to 8,00,000 Cusecs would last for subsequent 5 to 8 days and around 6,00,000 Cusecs for another subsequent 10 days at least.
Under this scenario, the inundation and riverine Flooding is expected at low lying areas of Sajawal , MirpurBataro, MirpurSakro, JhangShahi ,AllahRakhio, ShadadKot , Jamshoro, Matiari, Makaro, Ketibander, Shahbander in  Thatta and Hyderabad  Districts  along with the river bed.
All concerned authorities are requested to take precautionary measures to avoid loss of human lives and property.

WHAT IS TSUNAMI AND EARTHQUAKE

With a massive 8.8 earthquake striking near Chile and sending a tsunami across the Pacific, Hawaii readies itself for what could be a devastating strike. The island state has a history of being stricken by tsunamis, some generated locally but many from far off areas.

According to the U.S. Geological Survey (USGS), 50 tsunamis have been reported in Hawaii since the early 1800’s. Of those seven caused major damage. Five of those were generated from areas outside the state.

A tsunami is a series of waves that start out as a disturbance under the sea (such as an earthquake), and then increase in intensity. The disturbance causes the waves to travel outward in all directions. In this article, you will learn more about the causes and effects of tsunamis.

The motion of a tsunami is similar to what happens when you toss a rock in a lake and ripples start to form and move about the water. The time it takes for the waves to fully form is between 5 and 90 minutes. Sometimes, the wave speed in the open ocean will average 450 miles per hour.
Tsunamis that have reached a height of more than 100 feet have been recorded. The closer the waves get to reaching shallow coastal waters, the more normal they appear. The speed also decreases. If a tsunami closes in on the coastline, other conditions arise. It may grow in height and when it reaches the shore – it can be highly destructive.

An earthquake is not the only natural occurrence to cause a tsunami. Landslides, volcanic eruptions, and even meteorites have been known to cause an earthquake. A tsunami can start hundreds or even thousands of miles away from coastal areas. Location can play an important role in the effect of a tsunami. The regions at a great risk for suffering a tsunami are found less than 50 feet above sea level and within one mile of the shoreline.
Tsunamis cause a succession of high and low water levels. These kinds of crests and troughs usually occur about 10 to 45 minutes apart.
 The highest death toll from a tsunami happened on December 26, 2004, when an earthquake with a magnitude of 9 occurred under the Indian Ocean. The tsunami struck off the coast of Indonesia with a wave that affected the coastlines of nine different countries about the Indian Ocean. It was estimated in January 20, 2005 that the tsunami took the lives of at least 226,000 people. The total death toll is a number that will never be known.
Other Facts About Tsunamis

A 1964 earthquake in Alaska caused a tsunami with waves that measured between 10 and 20 feet high. The effects of the tsunami were felt along the coasts of California, Oregon, and Washington. In Alaska, more than $84 million in damage was incurred and the tsunami killed 123 people.
Since 1945, more people have lost their lives as a result of tsunamis than as a direct result of what happens with an earthquake.
Tsunamis are rare along the Atlantic coastline. However, a serious earthquake that took place on November 18, 1929 in the Grand Banks of Newfoundland. A tsunami developed and as a result, a great deal of damage and deaths took place at Placentia Bay, Newfoundland.
The most common way that a person dies during a tsunami is by drowning. Other causes of death include flooding, polluted water supplies, and damaged gas lines.
A tsunami that occurred in 1946 sent waves of 20 to 32 feet to crash into Hilo, Hawaii. The downtown part of the city flooded and in the process, 159 people were killed.
An estimate 10,000 people died in Hong Kong when a typhoon accompanied by a tsunami took place in 1906.
The Tsunami Warning Centers in Honolulu, Hawaii, and Palmer, Alaska, keep an eye on the disturbances that can lead to tsunamis. When a tsunami is detected – it is tracked. Tsunami warnings are then issued for areas in danger.

The worst tsunami to strike Hawaii in modern history occurred in 1946 and was caused by an earthquake in the Aleutian Islands. The tsunami struck without warning and claimed the lives of 170 people, mainly near Laupahoehoe and Hilo. Wave heights near Hilo reached 30 feet while the maximum height was 55 feet at the northern tip of the island near the Pololu Valley.

Waves as high as 35 feet struck Hilo, Hawaii and caused 61 deaths and $75 million in damage. Hilo Bay itself was struck the worst where 600 acres of land inland were inundated and only the most reinforced buildings survived. On Maui, the Kahului area was struck the worst where a warehouse and some houses were destroyed.

Tsunamis caused closer to the epicenter of a quake are often more deadly as there is less warning. Two locally generated tsunamis have also caused damage in Hawaii, one in 1868 and another in 1975. The 1868 tsunami destroyed two villages while waves from the 1975 tsunami claimed two lives.

As the wave approaches land, it slows but they increase in height
and the distance between them shrinks. (Wikipedia)A tsunami is typically generated by the movement of tectonic plate boundaries that move abruptly causing an earthquake. As one of the plates moves upward, it pushes the water up and outwards.

 

powerfull disaster history

Netherlands, 1228
Estimate: 100,000 lives lost from the flooding after some dykes broke.

Most of Europe and beyond, 1347-1350
Approximately 25 million lost their lives through the "Black Death" - the bubonic plague. Between 25 and 33% of the entire population of Europe at that time, plus millions in Asia and North Africa lost their lives.

Western Hemisphere, mostly 16th - 18th centuries
Untold millions of lives of American Indians were lost through the various sicknesses brought over from Europe (to which they had no previous exposure or resistance.) It's very difficult to get figures on this that are not politically infected one way or another (very high or very low).
China, 1556
The second deadliest earthquake was in the Chinese province of Shaanzi on February 2, 1556. It killed 830,000 people.
Indonesia, 1815
Mount Tambora (volcano) on Sumbawa Island released about 50 cubic kilometers of magma over at least 500,000 square kilometers of Indonesia and the Java Sea. That eruption and the resulting tsunami took at least 10,000 lives. But the famine and disease that followed took another 82,000 lives - total: over 90,000.
China, 1876 - 1879
The deadliest drought in recorded history was in China between 1876 and 1879. Rivers were dry, so most crops and livestock died. There was no food production in a 1-million km2 area of 9 provinces. The drought caused the death of an estimated nine million people.
Caribbean, 1902
Martinique, a small French colony in the Caribbean, has a volcano "Mont Pelee" which unleashed its fury and wiped out the town of St. Pierre. Only one survivor - pictured on right: a prisoner in a basement cell. (There's a good chance he got his life right with God before that day was over!)  But there were actually two others who also survived. see their amazing stories  Around 30,000 people were killed.
China, 1920
In the north China there was a drought that caused 20 million victims and took at least 500,00 lives.

China, Gansu - 1920
Gansu, China is hit with an earthquake measuring 8.6 and kills around 200,000 people.

Japan, 1923
A third of Tokyo is destroyed and much of Yokohama in an 8.3 earthquake which between 140,000 and 200,000 people.

China, 1927

An earthquake 7.9 - hit Nanshan City and took about 200,000 people.

China, 1931
A flood on the Changjiang River took at least 145,000 people (other estimates go over a million, but we have not confirmed that).

China, 1932
Another earthquake, this one northwest Gansu Province, killed about 70,000 people.

Bangladesh, 1970
In 1970, a cyclone and related floods killed about 500,000 people. With winds of up to 230 km/h, the cyclone crashed into the heavily populated coastal area of the Bay of Bengal, where several river deltas normally provide fertile land. The terrible winds produced massive waves, which wiped out many entire villages. Millions of people were left homeless in this country that is one of the most densely populated and one of the poorest in the world.
China, Tangshan - 1976
The worst earthquake damage in modern times was in northeast China in 1976. It was July 28 when a massive quake, measuring 8.3 on the Richter scale, shook the industrial mining city of Tangshan. Officially 255,000 people died, and another 164,000 were severely injured. But others (unofficial, but perhaps more accurate?) estimate that about 655,000 perished. Some ninety per cent of the buildings were destroyed. It took at least ten years and massive investment to rebuild the city.
Armenia, 1988
An earthquake measuring 6.9 on the Richter scale devastated Armenia in 1988. At that time Armenia was a republic of the Soviet Union.
