A large earthquake struck off the northeast coast of Japan but does not pose a tsunami threat to Hawaii, officials said Tuesday.

The quake, with a preliminary magnitude of 6.8, struck at 9:12 p.m. near the epicenter (11:12 a.m. in Hawaii), and was centered 21 miles southeast of Ofunato, Japan, at a depth of about 24 miles, according to the U.S. Geological Survey.

The earthquake was in the same region devastated by a major quake and tsunami in 2011. Japan’s meteorological agency said Tuesday’s earthquake was believed to be an aftershock of the magnitude 9.0 disaster four years ago.

The offshore quake shook a swath of northeast Japan, and was felt in Tokyo. There were no immediate reports of injuries or damage.

No abnormalities were reported from the Fukushima Dai-ichi nuclear power plant, which was destroyed in the 2011 quake, as well other plants in the area

Pacific Tsunami Warning Center officials on Oahu said, “based on all available data, there is no tsunami threat from this earthquake.”
