Tsunami watch issued after Indian Ocean quake

The U.S. Geological Survey reported a large 7.6 earthquake in the Indian Ocean about 250 kilometres from India's Andaman Islands, and issued a tsunami watch for India, Burma, Indonesia, Thailand and Bangladesh.

The U.S. Geological Survey reported a large, 7.6-magnitude earthquake in the Indian Ocean about 250 kilometres from India's Andaman Islands on Tuesday, and issued a tsunami watch for India, Burma, Indonesia, Thailand and Bangladesh.

The watch was later lifted by the USGS without any tsunami being recorded.

The Andaman Islands quake was reported to be 33 kilometres deep, the USGS said.

Meanwhile, the Japan Meteorological Agency said a strong earthquake with a preliminary magnitude of 6.6 has shaken Tokyo and surrounding areas. More than 30 people were slightly injured, officials said.

The Japanese agency also issued a tsunami warning from the Japanese temblor early Tuesday, which was centred off the Suruga Bay, southwest of Tokyo.

Japan's Kyodo news agency reported that two nuclear reactors at the Hamaoka nuclear plant in Omaezaki, Shizuoka, were quickly shut down.

The Central Japan Railway Co. suspended operations of the Shinkansen bullet trains, while the central government set up a task force at the prime minister's office, Kyodo reported.

The quake rattled furniture and walls in Tokyo but there have been no immediate reports of damages or casualties.

The quake occurred at a depth of 20 kilometres. Public broadcaster NHK said a small increase of waves of some 30 centimetres was observed along the coastline of Yaizu City.

Local trains were temporarily halted for safety checks.
