Sept. 20 (UPI) -- A 6.2-magnitude earthquake struck early Thursday the coast of Japan and 228 miles from a nuclear power plant that had a meltdown from a 2011 quake and subsequent tsunami.
The temblor hit at 2:37 a.m. in Japan, according to the U.S. Geological Survey. It was centered about 6 miles deep in the Pacific Ocean, 174 miles east-south of Kamaishi and about 315 miles northeast of Tokyo.
The Fukushima Daiichi plant suffered three meltdowns after a 9.0-magnitude quake 80 miles off the coast on March 11, 2011.
After the latest quake, no damage was reported in Japan and no tsunami warning were issued.
The earthquake was in the "Ring of Fire," an area around the edges of the Pacific Ocean, from Australia to the Andes, where 90 percent of all earthquakes occur. Tuesday's 7.1 earthquake in Mexico was also in the ring.
Two week ago, an 8.1 quake struck off the Pacific Coast of Mexico.
