Tsunami alerts issued for Hawaii, West Coast after magnitude 8.8 earthquake off Russia
A magnitude 8.8 earthquake struck off Russia's Kamchatka Peninsula on July 29, triggering tsunami alerts for the entire U.S. West Coast and prompting evacuation warnings in Hawaii, the U.S. Geological Survey said.
The earthquake was recorded at 7:24 p.m. ET, about 78 miles east-southeast of Petropavlovsk-Kamchatsky, Russia, the U.S. Geological Survey (USGS) said in its updated assessment. The agency said the quake was shallow, at a depth of about 12 miles.
Shortly before 11:30 p.m. ET, a tsunami advisory was upgraded to a warning for the coastal areas of California, from Cape Mendocino to the Oregon-California border, the weather service said. A tsunami warning means significant inundation is possible.
The tsunami warning also remains in effect from the coastal areas of Alaska from Samalga Pass to Attu, at the western end of the Aleutian Islands, and Hawaii.
A tsunami could cause damage along coastlines of all islands in Hawaii, the weather service said, adding "urgent action should be taken to protect lives and property." A tsunami is a long series of waves that may extensively flood coastal area and present dangers that could continue for many hours after the initial waves arrive. All shores are at risk in Hawaii no matter which direction they face.
