TOKYO (AP) -- An earthquake has rattled the Tokyo area hours after a stronger tremor caused a small tsunami on the northern Japanese coast.
The Japan Meteorological Agency said the second earthquake was magnitude 6.1. It was just off the coast of Chiba, east of Tokyo, at a rather shallow 10 kilometers (6 miles) below the sea surface.
There was no immediate report of damage or injury from the second quake. The tremor earlier Wednesday evening caused small swelling of water on the northern coast, including part of the region hit by last year's massive earthquake and tsunami
