2nd earthquake of day shakes northern Japan

Two strong earthquakes rattled northern Japan on Thursday, but neither caused any apparent damage or a tsunami. A magnitude-6.1 quake struck Thursday evening south of the northern island of Hokkaido, Japan's Meteorological Agency said. It hit about 465 miles (750 kilometers) northeast of Tokyo and 19 miles (30 kilometers) below the sea surface. The agency did not issue a tsunami warning. About 3,900 households in the towns of Erimo and Samani lost electricity shortly after the quake, but power was restored about an hour later, according to the Hokkaido Electric Power Co. (AP)
