Japan quake moved sea bed 24 metres: coastguard
Tokyo (AFP) April 6, 2011
The seabed near the epicentre of the massive earthquake that rocked Japan last month was shifted 24 metres (79 feet) by the tremor, the country's coastguard said Wednesday.
Sensors found that one part of the ocean floor had been stretched to a point 24 metres east-southeast of its position before the 9.0 undersea quake, which triggered a massive tsunami that engulfed large areas of Japan's northeast coast.
The undersea movement is more than four times bigger than any observed on land, where part of the Oshika peninsula in Miyagi prefecture was found to have shifted 5.3 metres.
The US Geological Survey (USGS) said in March that the force of the quake moved Honshu -- Japan's main island -- by 2.4 metres.

Bedrock in Central Asia that would have formed mountains instead was sand-blasted into dust, said lead author Paul Kapp. "No one had ever thought that wind could be this effective," said Kapp, a UA associate professor of geoscie ... read more
