Japan Earthquake, April 11, 2011: A strong M7.1 quake hits Japan anew

Exactly one month after the devastating 9.0-magnitude earthquake on March 11, Japan was struck by another strong quake which registered magnitude 7.1 on the Richter Scale on April 11, 2011 at 5:16 p.m., local time. (Update: magnitude downgraded to 6.6)

The epicenter was located at 38 km (24 miles) W (260°) of Iwaki, Honshu, Japan. It has a depth of 13.1 km. A tsunami warning has reportedly been issued. Reports say a half-meter high wave is expected at the Fukushima prefecture. (Update: tsunami warning lifted!)

Four days ago, Japan was also hit by a powerful 7.4-magnitude earthquake which killed 4 and injured 100 people.

There has been no reports of damage from the most recent quake.
