A strong earthquake struck central Japan on Saturday night, but there were no immediate reports of injuries or damage, and no tsunami warning was issued.
The magnitude-6.8 earthquake hit parts of Nagano city and surrounding areas the hardest, the Japan Meteorological Agency said. The U.S. Geological Survey measured the quake’s magnitude at 6.2.
The earthquake struck at 10:08 p.m. Japan time (1308 GMT) at a depth of 10 kilometers (6 miles). An apparent aftershock with a magnitude of 4.3 followed about 30 minutes later.
Japanese broadcaster NHK reported that a landslide blocked a road after the quake struck. NHK also said 200 homes were without power, and that Shinkansen bullet train service in the area had been suspended.
