Scientists at Japan's Meteorological Agency warn of relatively strong aftershocks that are expected to occur during the next several days.
Gen Aoki of the agency said at a news conference on Thursday night that people in stricken areas should be prepared for the possible collapse of buildings and landslides. He added the aftershocks could have intensities of up to 6-minus on the Japanese scale.
He also said the agency believes Thursday's quake occurred near a fault that caused major earthquakes several times in the past.
As for Mount Aso, a volcano near the epicenter, agency officials say instruments haven't detected any change in its activity after the earthquake.
