Powerful earthquakes leave at least 30 dead, destroy buildings along Japan's western coast

A series of powerful earthquakes hit western Japan, leaving at least 30 people dead and damaging buildings, vehicles and boats, with officials warning people in some areas on Tuesday to stay away from their homes because of a risk of more strong quakes.

Aftershocks continued to shake Ishikawa prefecture and nearby areas a day after a magnitude 7.6 temblor slammed the area on Monday afternoon.

Thirty people were confirmed dead in Ishikawa, officials said. Seven others were seriously injured, while damage to homes was so great that it could not immediately be assessed, they said.
