TOKYO, March 27 (UPI) -- A 6-magnitude earthquake rattled the eastern coast of Honshu, Japan's largest island, Tuesday, the U.S. Geological Survey said.
No tsunami warning was triggered.
The quake's epicenter, about 6 miles deep, was about 53 miles east of Morioka on Honshu Island, and about 318 miles north, northeast of Tokyo.
A fire official in Miyako City said no injuries or damage were reported, CNN said.
Japan's public broadcaster, NHK, said no irregular activity is reported from nuclear plants in the area.
A 4.9-magnitude quake, 21.3 miles deep, was recorded 40 minutes earlier, USGS said. Its epicenter was about 54 miles south-southeast of Mito and about 71 miles east of Tokyo, USGS said.
Slightly more than a year ago, a 9-magnitude earthquake triggered a huge tsunami off Japan, resulting in thousands of deaths and the world's worst nuclear crisis in a quarter century.
