A magnitude 8.9 earthquake slammed Japan's eastern coast Friday, unleashing a 13-foot (4-meter) tsunami that swept boats, cars, buildings and tons of debris miles inland. Fires triggered by the quake burned out of control up and down the coast, including one at an oil refinery.

At least one person was killed and there were reports of several injuries in Tokyo, hundreds of miles (kilometers) away, where buildings shook violently through the main quake and the wave of massive aftershocks that followed. A tsunami warning was issued for dozens of Pacific countries, as far away as Chile.

Japan's meteorological agency said that within two hours, large tsunamis washed ashore into dozens of cities along a 1,300-mile (2,100-kilometer) stretch of the country's eastern shore — from the northern island of Hokkaido to central Wakayama prefecture.

Prime Minister Naoto Kan said the quake caused "major damage in broad areas" but nuclear power plants in the area were not affected. The government prepared to send troops to the quake-hit areas.

"This is a rare major quake, and damages could quickly rise by the minute," said Junichi Sawada, an official with Japan's Fire and Disaster Management Agency.

TV footage showed waves of muddy waters sweeping over farmland near the city of Sendai, carrying buildings, some on fire, inland as cars attempted to drive away. Sendai airport, north of Tokyo, was inundated with cars, trucks, buses and thick mud deposited over its runways. Fires spread through a section of the city, public broadcaster NHK reported.

The tsunami also roared over embankments in Sendai city, washing cars, houses and farm equipment inland before reversing directions and carrying them out to sea. Flames shot from some of the houses, probably because of burst gas pipes.

Elsewhere, large fishing boats lay upturned on land, some distance from the sea.

Officials were trying to assess damage, injuries and deaths but had no immediate details. Police said at least one person was killed in a house collapse in Ibaraki prefecture, just northeast of Tokyo.

A large fire erupted at the Cosmo oil refinery in Ichihara city in Chiba prefecture near Tokyo and was burning out of control with 100-foot (30 meter) -high flames whipping into the sky.

NHK showed footage of a large ship being swept away by the tsunami and ramming directly into a breakwater in Kesennuma city in Miyagi prefecture.

In various locations along the coast, footage showed massive damage from the tsunami, with cars, boats and even buildings being carried along by waters. Partially submerged vehicles were seen bobbing in the water.

The U.S. Geological Survey said the quake was a magnitude 8.9, while Japan's meteorological agency measured it at 8.4. It struck at 2:46 p.m. and was followed by 12 powerful aftershocks, seven of them at least 6.3, the size of the quake that struck New Zealand recently.

A tsunami warning was extended to a number of Pacific, Southeast Asian and Latin American nations, including Japan, Russia, Indonesia, New Zealand and Chile. In the Philippines, authorities said they expect a 3-foot (1-meter) high tsunami.

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.

In downtown Tokyo, large buildings shook violently and workers poured into the street for safety. TV footage showed a large building on fire and bellowing smoke in the Odaiba district of Tokyo.

Several nuclear plants along the coast were partially shut down, but there were no reports of any radioactive leakage.

In central Tokyo, trains were stopped and passengers walked along the tracks to platforms. NHK said more than 4 million buildings were without power in Tokyo and its suburbs.

The ceiling in Kudan Kaikan, a large hall in Tokyo, collapsed, injuring an unknown number of people, NHK said.

Osamu Akiya, 46, was working in Tokyo at his office in a trading company when the quake hit.

It sent bookshelves and computers crashing to the floor, and cracks appeared in the walls.

"I've been through many earthquakes, but I've never felt anything like this," he said. "I don't know if we'll be able to get home tonight."

Footage on NHK from their Sendai office showed employees stumbling around and books and papers crashing from desks. It also showed a glass shelter at a bus stop in Tokyo completely smashed by the quake and a weeping woman nearby being comforted by another woman.

Several quakes had hit the same region in recent days, including a 7.3 magnitude one on Wednesday.

Thirty minutes after the main quake, tall buildings were still swaying in Tokyo and mobile phone networks were not working. Japan's Coast Guard has set up a task force and officials are standing by for emergency contingencies, Coast Guard official Yosuke Oi said.

"I'm afraid we'll soon find out about damages, since the quake was so strong," he said.

In Tokyo, hundreds of people were evacuated from Shinjuku train station, the world's busiest, to a nearby park. Trains were halted.

Tokyo's main airport was closed. A large section of the ceiling at the 1-year-old airport at Ibaraki, about 50 miles (80 kilometers) northeast of Tokyo, fell to the floor with a powerful crash.

Dozens of fires were reported in northern prefectures of Fukushima, Sendai, Iwate and Ibaraki. Collapsed homes and landslides were also reported in Miyagi.

Japan's worst previous quake was in 1923 in Canto, which killed 143,000 people, according to USGS. An earthquake in Kobe city in 1996 killed 5,502 people.

The biggest earthquake to hit Japan in 140 years struck the northeast coast on Friday, triggering a 10-metre tsunami that swept away everything in its path, including houses, cars and farm buildings on fire, media and witnesses said.

At least one person was killed in Fukushima prefecture, north of Tokyo where four million homes were without power. The 8.9 magnitude quake caused many injuries, public broadcaster NHK said, sparked fires and the wall of water, prompting warnings to people to move to higher ground in coastal areas. Some news agencies have reported three deaths until now.

The Philippines, Taiwan and Indonesia all issued tsunami alerts, reviving memories of the giant tsunami which struck Asia in 2004. The Pacific Tsunami Warning Center issued alerts for countries as far away as Colombia and Peru.

There were several strong aftershocks. In the capital Tokyo, buildings shook violently. An oil refinery near Tokyo was on fire, with dozens of storage tanks under threat.

"I was terrified and I'm still frightened," said Hidekatsu Hata, 36, manager of a Chinese noodle restaurant in Tokyo's Akasaka area. "I've never experienced such a big quake before."

A strong earthquake triggered a small tsunami along Japan's northeastern coast Wednesday and shook buildings hundreds of miles away in Tokyo. There were no immediate reports of significant damage or injuries.

Some train lines in the northeastern prefecture of Iwate were temporarily stopped after the magnitude 7.3 quake, but they were restarted shortly after. Tohoku Electric Power said there was no damage at its nuclear power facility in the region.

A 24-inch (60-centimeter) tsunami reached the coastal town of Ofunato and other towns reported smaller waves reached shore about 30 minutes after the quake, which occurred at 11:45 a.m.

It was centered about 90 miles (150 kilometers) off the northeastern coast at a depth of about five miles (eight kilometers), Japan's meteorological agency said.

"We have confirmed that small tsunami have come up on the shores, but we have no reports of damage at this point," said Shinobu Nagano, an emergency and disaster response official in Iwate. "We are still trying to determine the impact of the quake."

The Pacific Tsunami Warning Center in Hawaii said a Pacific-wide tsunami was not expected.

In Tokyo — about 270 miles (440 kilometers) from the epicenter — office buildings swayed and creaked for about 30 seconds.

There was a 6.3 magnitude aftershock shortly after the main quake, the meteorological agency said.

Japan lies on the "Ring of Fire" — an arc of earthquake and volcanic zones that stretches around the Pacific Rim and where about 90 percent of the world's quakes occur.

In 1933, about 3,000 people were killed around Ofunato by an earthquake and tsunami that had a maximum wave height of 94 feet (28 meters), according to the U.S. Geological Survey. In 1896, a magnitude 8.5 earthquake generated a tsunami that killed 27,000 people in the area.
