Two powerful earthquakes have struck Asia, killing one and injuring dozens of other people in coastal Japan and sending panicked residents into the streets as tsunami warnings were issued for countries skirting the Indian Ocean.
The US Geological Survey said the first quake, registering magnitude 7.6, hit the Indian Ocean about 160 miles north of Port Blair in India's Andaman Islands.
A tsunami watch was called for India, Burma, Indonesia, Thailand and Bangladesh, but was later lifted.
A police official in Port Blair said there were no injuries or damage caused by the quake.
"But people ran out of their homes in fear as they remembered the 2004 tsunami," he said, referring to waves triggered by a magnitude 9.0 earthquake that killed 230,000 people in a dozen countries around the Indian Ocean.
The quake was centred at a depth of 20.6 miles, the US Geological Survey said. An aftershock measuring 4.8 shook the same area 15 minutes later at a depth of 21.7 miles, it said.
In Japan, one person was killed and several dozen injured when a 6.5-magnitude quake hit Tokyo and nearby areas, halting trains and forcing two nuclear reactors to shut down for safety checks.
Police said one 43-year-old woman was killed by falling debris and at least 63 people were injured.
Japan's public broadcaster, NHK, reported that more than 80 people suffered minor injuries.
Japan's Meteorological Agency - which downgraded the quake from magnitude 6.6 - also issued a tsunami warning, but that was later lifted. The quake was centred off Suruga Bay, south-west of Tokyo, at a depth of 12 miles.
