Two strong aftershocks rattled northern Japan on Thursday, weeks after a powerful earthquake killed 39 people and injured thousands. The tremors sent residents dashing under tables and caused at least one injury.
Late Thursday, a magnitude-5.7 earthquake jolted the country's northernmost main island of Hokkaido, but there were no immediate reports of injuries. The earthquake was centered 37 miles underground, near the island of Kunashiri, about 590 miles north of Tokyo, the Meteorological Agency said.
The aftershock, about 500 miles north of the magnitude-6.8 tremor that struck rural Niigata prefecture Oct. 23, was in an area not affected by the initial tremor.
Earlier Thursday, a magnitude-5.2 aftershock struck an area still recovering from last month's quake.
