An earthquake with a preliminary magnitude of 5.4 shook Japan Saturday about 5:49 a.m. local time (Friday about 4:49 p.m. EDT), according to the U.S. Geological Survey. The epicenter of the quake at a depth of 29.3 miles was 20 miles southeast of Tokyo, the USGS reported.

There were no immediate reports of major damage or injuries, the Associated Press said. And the earthquake has not resulted in any tsunami warnings. Because of recent heavy rains, however, it could potentially cause landslides in some areas.

The earthquake came just one day after extreme flooding in the city of Joso, located north of Tokyo, as BBC News reported. Heavy rain came in association with a tropical storm system featuring extreme winds.
