Hundreds killed in tsunami after 8.9 Japan quake


TOKYO – A ferocious tsunami spawned by one of the largest earthquakes on record slammed Japan's eastern coast Friday, killing hundreds of people as it swept away ships, cars and homes while widespread fires burned out of control.

Hours later, the tsunami hit Hawaii but did not cause major damage. Warnings blanketed the Pacific, putting areas on alert as far away as South America, Canada, Alaska and the entire U.S. West coast. In northeastern Japan, the area around a nuclear power plant was evacuated after the reactor's cooling system failed.

Police said 200 to 300 bodies were found in the northeastern coastal city of Sendai, the city in Miyagi prefecture, or state, closest to the epicenter. Another 110 were confirmed killed, with 350 people missing. Police also said 544 people were injured.

The magnitude-8.9 offshore quake unleashed a 23-foot (seven-meter) tsunami and was followed for hours by more than 50 aftershocks, many of them of more than magnitude 6.0.

Dozens of cities and villages along a 1,300-mile (2,100-kilometer) stretch of coastline were shaken by violent tremors that reached as far away as Tokyo, hundreds of miles (kilometers) from the epicenter. A large section of Kesennuma, a town of 70,000 people in Miyagi, burned furiously into the night with no apparent hope of being extinguished, public broadcaster NHK said.

"The earthquake has caused major damage in broad areas in northern Japan," Prime Minister Naoto Kan said at a news conference.

The government ordered thousands of residents near a nuclear power plant in the city of Onahama to move back at least two miles (three kilometers) from the plant. The reactor was not leaking radiation but its core remained hot even after a shutdown. The plant is 170 miles (270 kilometers) northeast of Tokyo.

Trouble was reported at two other nuclear plants as well, but there was no radiation leak at either of them.

Japan's coast guard said it was searching for 80 dock workers on a ship that was swept away from a shipyard in Miyagi.

Even for a country used to earthquakes, this one was of horrific proportions because of the tsunami that crashed ashore, swallowing everything in its path as it surged several miles (kilometers) inland before retreating. The apocalyptic images on Japanese TV of powerful, debris-filled waves, uncontrolled fires and a ship caught in a massive whirlpool resembled scenes from a Hollywood disaster movie.

Large fishing boats and other vessels rode high waves ashore, slamming against overpasses or scraping under them and snapping power lines along the way. Upturned and partially submerged cars bobbed in the water. Ships anchored in ports crashed against each other.

The tsunami roared over embankments, washing anything in its path inland before reversing directions and carrying the cars, homes and other debris out to sea. Flames shot from some of the homes, probably because of burst gas pipes.

Waves of muddy waters flowed over farmland near Sendai, carrying buildings, some of them ablaze. Drivers attempted to flee. Sendai airport was inundated with thick, muddy debris that included cars, trucks, buses and even light planes.

Highways to the worst-hit coastal areas buckled. Telephone lines snapped. Train service in northeastern Japan and in Tokyo, which normally serve 10 million people a day, were suspended, leaving untold numbers stranded in stations or roaming the streets. Tokyo's Narita airport was closed indefinitely.

President Barack Obama said the U.S. "stands ready to help" Japan.

Jesse Johnson, a native of the U.S. state of Nevada who lives in Chiba, north of Tokyo, was eating at a sushi restaurant with his wife when the quake hit.

"At first it didn't feel unusual, but then it went on and on. So I got myself and my wife under the table," he told The Associated Press. "I've lived in Japan for 10 years, and I've never felt anything like this before. The aftershocks keep coming. It's gotten to the point where I don't know whether it's me shaking or an earthquake."

NHK said more than 4 million buildings were without power in Tokyo and its suburbs.

As night fell, Tokyo's streets were jammed with cars, buses and trucks trying to get around and out of the city. Pedestrians swarmed the sidewalks to walk home, or at least find a warm place to spend the night as the temperatures dropped.

Tomoko Suzuki and her elderly mother stood on a crowded downtown corner, unable to get to their 29th-floor condominium because the elevator wasn't working. They unsuccessfully tried to hail a taxi to a relative's house and couldn't find a hotel room.

"We are so cold," said Suzuki. "We really don't know what to do."

A large fire erupted at the Cosmo oil refinery in the city of Ichihara and burned out of control with 100-foot (30-meter) flames whipping into the sky.

"Our initial assessment indicates that there has already been enormous damage," Chief Cabinet Secretary Yukio Edano said. "We will make maximum relief effort based on that assessment."

He said the Defense Ministry was sending troops to the hardest-hit region. A utility aircraft and several helicopters were on the way.

Also in Miyagi prefecture, a fire broke out in a turbine building of a nuclear power plant, but it was later extinguished, said Tohoku Electric Power Co.

A reactor area of a nearby plant was leaking water, the company said. But it was unclear if the leak was caused by the tsunami or something else. There were no reports of radioactive leaks at any of Japan's nuclear plants.

Jefferies International Ltd., a global investment banking group, estimated overall losses of about $10 billion.

Hiroshi Sato, a disaster management official in northern Iwate prefecture, said officials were having trouble getting an overall picture of the destruction.

"We don't even know the extent of damage. Roads were badly damaged and cut off as tsunami washed away debris, cars and many other things," he said.

The U.S. Geological Survey said the 2:46 p.m. quake was magnitude 8.9, the biggest to hit Japan since record-keeping began in the late 1800s and one of the biggest ever recorded in the world.

The quake struck at a depth of six miles (10 kilometers), about 80 miles (125 kilometers) off the eastern coast, the agency said. The area is 240 miles (380 kilometers) northeast of Tokyo. Several quakes hit the same region in recent days, including one measured at magnitude 7.3 on Wednesday that caused no damage.

A tsunami warning was extended to a number of areas in the Pacific, Southeast Asia and Latin America, including Japan, Russia, Indonesia, New Zealand and Chile. In the Philippines, authorities ordered an evacuation of coastal communities, but no unusual waves were reported.

Thousands fled homes in Indonesia after officials warned of a tsunami up to 6 feet (2 meters) high, but waves of only 4 inches (10 centimeters) were measured. No big waves came to the Northern Mariana Islands, a U.S. territory, either.

The first waves hit Hawaii about 9 a.m. EST (1400 GMT). A tsunami about 7 feet (2.1 meters) high was recorded on Maui and a wave at least 3 feet (a meter) high was recorded on Oahu and Kauai. Officials warned that the waves would continue and could get larger.

Japan's worst previous quake was a magnitude 8.3 temblor in 1923 in Kanto that killed 143,000 people, according to USGS. A 7.2-magnitude quake in Kobe in 1996 killed 6,400 people.

Japan lies on the "Ring of Fire" — an arc of earthquake and volcanic zones stretching around the Pacific where about 90 percent of the world's quakes occur, including the one that triggered the Dec. 26, 2004, Indian Ocean tsunami that killed an estimated 230,000 people in 12 nations. A magnitude-8.8 temblor that shook central Chile in February 2010 also generated a tsunami and killed 524 people.

Another day, another earthquake. Except the Magnitude 8.9 tremor off the coast of Honshu, Japan, will be a standout event for 2011 - perhaps not in terms of the eventual death toll it brings, but certainly in scale.
There are usually only one or two quakes of this size every year. And even for a country such as Japan, which is very familiar with seismic hazards, this is extraordinary.
The history books show there have been seven quakes rated at 8.0 or greater since 1891 in Japan. And with big tremors come big aftershocks.


Following the initial 8.9 event at 1446 local time (0546 GMT), a sequence of major tremors was initiated - six of them within an hour-and-a-quarter that were all bigger than or all equal to last month's quake in Christchurch, New Zealand (6.3). The largest of the aftershocks was a 7.1.
Some of the early video footage to emerge from Japan was dramatic - city workers hanging on to their desks as everything rocked around them and buildings on fire being swept across farmland as tsunami waters washed inland.
The tectonics in this part of the world are, of course, well-understood. It is one of the most seismically active areas on Earth. The country accounts for about 20% of global quakes of Magnitude 6.0 or greater, and seismometers are recording some kind of event every five minutes, on average.
Japan lies on the infamous "Ring of Fire", the line of frequent quakes and volcanic eruptions that encircles virtually the entire Pacific Rim.
At this location, the dense rock making up the Pacific Ocean's floor is being pulled down underneath Japan as it moves westwards towards Eurasia. The epicentre was well out to sea - some 130km from the city of Sendai; but at a relatively shallow depth below the seabed - just 24km.
This clearly led to a fair degree of vertical upward movement in the bed as the resultant tsunami were soon hitting shorelines.
The US-run Pacific Tsunami Warning Center said amplitudes of up 7.3m were recorded on the coast of Japan. Even out in the deep ocean, the specialist tsunami warning buoys were recording wave amplitudes of a metre, which is considerable.
This means waves will reach out across the Pacific, towards the Philippines, Hawaii and perhaps even to be recorded on the North and South American landmass.
What is likely to interest seismologists will be the association with a number of very strong foreshocks in recent days.
These began on 9 March with a Magnitude 7.2 event just 40km from Friday's earthquake, and continued with a further three earthquakes greater than Magnitude 6 on the same day.
In terms of public awareness and reaction, these foreshocks could turn out to be quite important because they will have reminded people what they are supposed to do in a big quake to protect themselves.
Remember, the scale used to measure earthquakes is not a simple linear one.
Each step in magnitude equates to a 32 times jump in the release of energy. As a consequence, Friday's 8.9 event was some 250 times more energetic than anything seen on Wednesday this week; and about 1,400 times more energetic than the Great Hanshin, or Kobe, earthquake in 1995 (M 6.8).

Earthquake and Tsunami NEAR THE EAST COAST OF HONSHU JAPAN

Strong earthquakes  hit the Tohoku Region in the afternoon of March 11, triggering several meter high tsunami waves that caused massive destruction in areas along the Pacific coast of eastern Japan, especially in Miyagi, Iwate  and Fukushima Prefectures.

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).

The earthquake itself caused scattered fires and destruction across the eastern Tohoku  and eastern Kanto area, but there is no widespread damage in any major city as seen in Kobe in 1995. The tsunami, however, caused extensive damage in coastal areas along the Pacific coast of northeastern Japan.

Effect on transportation

Tokyo's Narita Airport was closed temporarily but can be expected to re-open in the near future. Tokyo's Haneda Airport was re-opened partially a few hours after the earthquake. Sendai Airport was hit by the tsunami and is likely to remain closed for some time to come.

Many shinkansen and train lines in Eastern Japan were stopped and remain out of service or have delays. It would not be surprising if some shinkansen lines in northeastern Japan remained out of service for a couple of days, especially the Tohoku Shinkansen. However, it does not seem that any shinkansen line suffered any major damage. The Tokaido Shinkansen between Tokyo and Osaka has already resumed operation.

Effect on trips to Japan

The effect on tourist activities (apart from short term transportation issues) is likely to be rather low. Among major tourist spots, Matsushima lies in the coastal area that got badly hit by tsunami, but no details about eventual damage are available yet. Central Sendai did not suffer widespread damage. There is currently no information on any other major tourist destination affected.

After shocks can be expected to continue for several days in the Tohoku Region.

Overall, however, there is little reason to change or cancel travel plans for Japan unless you were planning to visit the coastal areas of the eastern Tohoku Region.
Hawaii and Guam residents told to leave coastal areas

* Tsunami could wash over some Pacific islands - Red Cross (Adds Guam details, Red Cross warning)

By Suzanne Roig and Jorene Barut

HONOLULU, March 10 (Reuters) - Hawaii ordered evacuations from coastal areas due to the threat of a tidal wave set off by Friday's earthquake in Japan as a tsunami warning was extended to the whole of the Pacific basin, except mainland United States and Canada.

Authorities also ordered evacuation from low-lying areas on the U.S. island territory of Guam in the western Pacific, where residents there were urged to move at least 50 feet (15 meters) above sea level and 100 feet (30 meters) inland.

Tsunami Alert

Tsunami Alert for New Zealand, the Philippines, Indonesia, Papua New Guinea, Hawaii, and others. Waves expected over the next few hours, caused by 8.9 earthquake in Japan.
