S everal earthquakes, including a 7.4 magnitude one, struck off the Russian coast on Sunday, according to the U.S. Geological Survey, prompting brief warnings of potential tsunami waves on the nearby peninsula and farther across the Pacific in Hawaii.

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 tsunami warning that was then downgraded to an advisory was triggered by a 7.3-magnitude quake in the Gulf of Alaska on Wednesday, according to data from the U.S. Tsunami Warning System, which is part of the National Weather Service.
