A powerful undersea earthquake south of Japan has shaken buildings in Tokyo and been felt across the country.
The US Geological Survey said the 7.8-magnitude earthquake was centred 874km (543 miles) from the Japanese capital, at a depth of more than 660km.
The earthquake struck at 20:30 local time (11:30 GMT). Buildings in the capital swayed for almost a minute as the quake built in intensity.
There are no reports of serious damage. No tsunami alert was issued.作者: nmaverick 时间: 2015-5-31 12:26
