Tsunami Warning in California: Here are the Details

In the early hours of July 29, 2025, a massive 8.8 magnitude earthquake struck off Russia’s Kamchatka Peninsula, prompting tsunami alerts stretching across the Pacific—including tsunami warning California, tsunami warning Hawaii, tsunami warning Washington, tsunami warning Oregon and coastal regions of California. Although waves arrived in some places, the most severe impacts were limited to Russia, Japan and Hawaii, while the California tsunami warning was later downgraded.

Kamchatka Earthquake Triggers Pacific‑wide Tsunami Alerts

A powerful earthquake with initial magnitude reporting between 8.7 and 8.8 hit near the Kamchatka Peninsula, Russia, at a shallow depth of roughly 19 km, centered just over 125 km from Petropavlovsk‑Kamchatsky. This quake is tied as one of the strongest globally since the 2011 Japan earthquake, and the most powerful in the region since the infamous 1952 Severo‑Kurilsk earthquake. The intense seismic activity triggered a tsunami warning for Hawaii, Russia’s Kuril coast, and a tsunami advisory or watch for the U.S. West Coast, including California, Oregon, and Washington.
