A massive 8.8 magnitude earthquake struck off Russia’s Kamchatka Peninsula on Tuesday, triggering tsunami waves across the Pacific and prompting widespread evacuations.
The U.S. Geological Survey reported the epicenter 74 miles southeast of Petropavlovsk-Kamchatsky. Initial tsunami waves hit Russia and Japan, with the U.S. West Coast and Hawaii following soon after.
The National Oceanic and Atmospheric Administration issued tsunami warnings and advisories for Hawaii, California, Oregon, Washington, Alaska, and U.S. territories. A wave over 5 feet was observed in Maui. Flights in and out of Maui were canceled, and hotels evacuated.
A Tsunami Advisory is in effect for the coastal areas of California. First wave arrival is expected around 1150 PM PDT. Multiple waves are expected, lasting for 10-36 hours. Move off the beach and out of harbors/marinas. Mariners are advised to get to depth of 30 fathoms. pic.twitter.com/Qt95uhuLli
