An earthquake with a preliminary magnitude of 8.7 that occurred in Eastern Russia has prompted a tsunami watch for coastal areas that include the California coastline, including in Los Angeles and Orange counties.
The quake, according to the U.S. Geological Survey, struck at 4:25 p.m. Pacific Daylight Time at a depth of around 11 miles 80 miles southeast of Petropavlovsk Kamchatka.
“Tsunami watches are an advance notice to areas that could be impacted by a tsunami at a later time,” according to the National Oceanic and Atmospheric Administration. “Watch areas may be upgraded to a warning or advisory status, or canceled, based on new information.”

Residents in coastal areas under a tsunami watch are urged to stay alert for additional updates and be aware of estimated tsunami start times, some of which include the following:
- L.A. Harbor, July 30 at 1:05 a.m.
- Santa Barbara, July 30 at 12:50 a.m.
- Newport Beach, July 30 at 1:10 a.m.
- La Jolla, July 30 at 1:15 a.m.
- San Francisco, July 30 at 12:50 a.m.
The tsunami watch will remain in effect until further notice.
