A massive earthquake struck southern Japan Saturday, a day after the same region was rocked by a temblor that killed 9 people.
The United States Geological Survey reported the magnitude 7.0 earthquake struck Saturday morning at 1:25 a.m. in the city of Kumamoto on the island of Kyushu, at a depth of 25 miles.
It briefly triggered a tsunami advisory that the Japan Meteorological Agency later lifted. At least six aftershocks rattled the region after Saturday's quake, the strongest of which was a magnitude-5.8, the USGS sad.
It wasn't immediately clear whether there were casualties from the latest quake. Some residents were reportedly trapped under buildings, according to national broadcaster NHK.
A hospital near the epicenter told NHK it had lost power after Saturday's quake and was relying on generators, Reuters reported.
