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.

According to the Pacific Tsunami Warning Center, based on all available data there is no tsunami threat to Hawaii.

A magnitude‑7.4 earthquake off Russia's Kamchatka Peninsula triggered a brief Saturday night tsunami watch for the Hawaiian Islands. It was lifted in under 40 minutes, but why are Hawaiian locals and tourists being asked to keep their guards up?
