HONOLULU, Hawaii – A magnitude 8.2 earthquake has hit 373 miles below the surface in the Sea of Okhotsk.

The epicenter is 223 miles west southwest of Esso, Russia, according to measurements by the United States Geological Survey.

The Pacific Tsunami Warning Center was quick to report that no tsunami was expected, posting this message on their website:
