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.

A major earthquake with a preliminary magnitude of 7.3 initially triggered a tsunami warning for the southern Alaska Peninsula. It was later downgraded to an advisory.

The Pacific Tsunami Warning Center (PTWC) has cancelled a tsunami watch issued for the Hawaiian islands. The alert came after a 7.5 magnitude earthquake struck off the east coast of Russia. Officials said the quake happened just before 6:30 a.
