On Sunday, July 20, multiple earthquakes, including one that was 7.4 magnitude, struck the Russian coast. The U.S. National Tsunami Warning Center (USNTWC) initially issued a tsunami watch for Hawaii as a result at 9:03 p.m. local time on Saturday.

The tsunami watch for Hawaii has been cancelled following a 7.5 magnitude earthquake struck off the east coast of the Kamchatka Peninsula in Russia.
