A brief tsunami watch for Hawaii was called off, but experts warn residents to remain prepared for future threats.

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.

Powerful earthquakes up to 7.4 magnitude struck Russia’s Kamchatka Peninsula, triggering tsunami alerts across the Pacific before being lifted. Aftershocks continue as officials monitor the region.
