There is no tsunami threat to Hawaii from a magnitude-6.8 quake south of Japan, the Pacific Tsunami Warning Center advises.

The quake happened at 3:43 p.m. Hawaii time Sunday.

“Base on all available data, a destructive Pacific-wide tsunami is not expected,” the center said in an online statement.

The U.S. Geological Survey, which set the magnitude at 6.6, said the epicenter was 44 miles east of Su’ao, Taiwan, at a depth of 18 miles. That places it in Japan’s southwestern Ryukyu Islands.
