The Washington Post reported earlier this morning:
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.
The shaking was not felt in Tokyo, though a morning quake was.
That magnitude-6.0 temblor struck just off the coast near the nuclear power plant damaged by the March 11 earthquake and tsunami.
