The Pacific Tsunami Warning Center on Oahu has confirmed that there is no tsunami threat from a 6.8 magnitude earthquake off Japan.

The quake hit at 2:28 p.m. Sunday near the epicenter (7:28 p.m. Saturday Hawaii time) under the sea several hundred miles southeast of Honshu, Japan, shaking buildings in the capital.

The quake, which struck near the uninhabited island of Torishima in the Pacific Ocean, was centered about 307 miles south-southwest of Tokyo, and about 216 miles below the sea, the U.S. Geological Survey said.

Japan’s Meterological Agency said there was no danger of a tsunami.

Buildings in Tokyo shook but there were no immediate reports of damage or injuries. Express trains in northern and central Japan were suspended temporarily for safety checks but later resumed.

No abnormalities were reported at power plants in the region, including the crippled nuclear power plant hit by the March earthquake and tsunami, public broadcaster NHK reported.

Northeastern Japan was devastated by a massive earthquake and tsunami on March 11 that left nearly 20,000 people dead or missing. Japan, which lies along the Pacific “Ring of Fire,” is one of the world’s most seismically active countries.
