FUKISHIMA (AP) - A 5.3-magnitude earthquake has hit the Japanese prefecture that is home to the nuclear power plant crippled in the March 2011 earthquake and tsunami.
The U.S. Geological Survey says the quake struck early Friday at a depth of about 13 miles (22 kilometers) under Fukushima Prefecture and about 110 miles (177 kilometers) northeast of Tokyo.
The Pacific Tsunami warning Center did not issue an alert.
The region lies on the "Ring of Fire" - an arc of earthquake and volcanic zones that stretches around the Pacific Rim. About 90 percent of the world's quakes occur in the region.
