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?

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