At least two people died and 19 houses collapsed after an earthquake struck southern Japan late Thursday, authorities said. An unknown number of people were still trapped under collapsed buildings Thursday night, Chief Cabinet Secretary Yoshihide Suga said.

The U.S. Geological Survey said the magnitude-6.2 quake struck near Ueki, Japan. Several smaller aftershocks occurred shortly afterward.

Several fires also broke out in the town of Mashiki, Japanese broadcaster NHK said.

The two deaths occurred in Mashiki, the Kumamoto Prefecture Disaster Management Office said. One person died in a collapsed house, and the other died in a fire.
