Earthquakes shook northeastern Japan Saturday, causing landslides and injuring hundreds of people, according to government reports.

Two quakes – the first measuring 5.5 on the Richter scale and the second measuring 6.2 – were centered some 190 miles north of Tokyo.

Aftershocks continued to shake the region Saturday. Some 2,500 people remained evacuated. Most of the injuries were not serious.

Japanese officials were concerned that bad weather would compound the damage. "We hope that the earthquakes are settling down, but we are worried about further damage because of the heavy rain," said Yoshitada Konoike, cabinet minister for disaster management, at a news conference in Tokyo.

The rain heightens the risk for more landslides.
