A magnitude 6.0 earthquake struck off the coast of Iwate, Japan Tuesday in the same region that was badly damaged by last year's earthquake and tsunami.
Initial reports from the Japanese meteorological agency rated the quake's magnitude at 6.4 and said that sea levels may change slightly, but there was no risk for a tsunami.
There were no reports of damage or injuries, and local authorities reported that no nuclear facilities in the area were damaged.
On March 14, a magnitude 6.9 earthquake struck the region prompting a tsunami warning and evacuation alert for coastal communities.
On March 11, 2011 a 9.0 magnitude earthquake triggered a massive tsunami in northeastern Japan that killed almost 20,000 people and crippled the Fukushima nuclear plant.
