Updates:Atleast 29 people were reported killed after a huge earthquake and tsunamis

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.

At least 29 people were reported killed after a huge earthquake and tsunamis up to 10 meters (33 feet) high slammed into the Pacific coast Friday.

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.

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

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

GREAT KANTO QUAKE

"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."

Stunning TV footage showed the tsunami carrying the debris and fires across a large swathe of coastal farmland near the city of Sendai, which has a population of one million. The pictures suggested the death toll was going to rise.

Sendai is 300 km (180 miles) northeast of Tokyo and the epicentre at sea was not far away.

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.

Thick smoke was also pouring out of an industrial area in Yokohama's Isogo area. TV footage showed boats, cars and trucks floating in water after a small tsunami hit the town of Kamaichi in northern Japan. An overpass, location unknown, appeared to have collapsed into the water.

Kyodo news agency said there were reports of fires in Sendai where waves carried cars across the runway at the airport.

The western prefecture of Wakayama ordered 20,000 people to evacuate after further tsunami warnings.

"The building shook for what seemed a long time and many people in the newsroom grabbed their helmets and some got under

their desks," Reuters correspondent Linda Sieg said in Tokyo.

"It was probably the worst I have felt since I came to Japan more than 20 years ago."


GREAT KANTO QUAKE

The quake was the biggest since 1872, according to the Japan Meteorological Agency. It surpasses the Great Kanto quake of September 1, 1923, which had a magnitude of 7.9, killed more than 140,000 people in the Tokyo area. Seismologists had said another such quake could strike the city any time. The 1995 Kobe quake caused $100 billion in damage and was the most expensive natural disaster in history. Economic damage from the 2004 Indian Ocean tsunami was estimated at about $10 billion.

The Tokyo stock market extended losses after the quake. The central bank said it would do everything to ensure financial stability.

Passengers on a subway line in Tokyo screamed and grabbed other passengers' hands during the quake. The shaking was so bad it was hard to stand, said Reuters reporter Mariko Katsumura.

Hundreds of office workers and shoppers spilt 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, crowds were watching and pointing to construction cranes on an office building up the street with voices saying, "They're still shaking!," "Are they going to fall?"

Asagi Machida, 27, a web designer in Tokyo, sprinted from a coffee shop when the quake hit.

"The images from the New Zealand earthquake are still fresh in my mind so I was really scared. I couldn't believe such a big earthquake was happening in Tokyo."

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 8.9.

A police car drove down Hitotsugi Street, lights flashing, announcing through a bullhorn that there was still a danger of shaking.

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.
