Tsunami Advisory Cancelled for Los Angeles County Wednesday Morning. Remains in effect for Santa Barbara and Ventura County

A powerful magnitude 8.8 earthquake struck near Russia’s Kamchatka Peninsula, triggering tsunami alerts across the Pacific. This is the largest earthquake anywhere on the planet this decade, and one of the most powerful earthquakes ever recorded. Tsunami warnings were active for Japan and Hawaii and tsunami advisories are in effect for California, Oregon, Washington, Alaska (including the Aleutian Islands), British Columbia, and Guam.

Update from Los Angeles County Emergency Management, Wednesday at 7 am PST: "Per the @NWS_NTWC: the Tsunami Advisory has been lifted for Los Angeles County. A tsunami was generated but no longer meets criteria for an advisory. Some areas may see sea level changes. Decision to reoccupy beaches, marinas, and waterways must be made by local officials."

Flooding was reported in Hilo after water levels increased nearly 6 feet in just a few minutes as tsunami waves pushed through. Some sources said it was just one hotel and one street in Hilo that was flooded. "Hilo Bay is notoriously the most susceptible city in Hawaii to tsunamis due to the shape of the bay which acts like a funnel, amplifying incoming tsunami waves."

A tsunami warning is in effect for Hawaii following an 8.7 magnitude earthquake off Russia's Kamchatka Peninsula on July 29, 2025, at 1:25 p.m. HST. The Pacific Tsunami Warning Center (PTWC) issued the warning at 2:43 p.m. HST, with the first tsunami wave expected to reach Hawaii around 7:15 p.m. HST, starting with Hanalei at 7:10 p.m. HST. Sirens are sounding across all Hawaiian islands every ten minutes after the hour for three hours, urging coastal evacuation due to the risk of destructive waves. The National Weather Service notes that tsunami heights are unpredictable, and the first wave may not be the largest, with danger persisting for hours. Residents are advised to evacuate tsunami zones immediately, move inland, and avoid coastal areas. An interactive evacuation map is available through the Hawaii Emergency Management Agency. The situation is still developing, and updates are being monitored by the PTWC.[](https://abcnews.go.com/US/tsunami-watch-issued-hawaii-after-80-magnitude-earthquake/story?id=124190121)[](https://www.hawaiinewsnow.com/2025/07/29/tsunami-watch-issued-hawaii-after-m8-earthquake-off-russia/)

Watch Chignik Bay, Alaska - The Cal./Mexico Border Issued at: 7/29/2025, 5:19:26 PM. As of July 29, 2025, a tsunami warning is in effect for parts of Russia's Kamchatka Peninsula following a magnitude 8.7 earthquake that struck off its east coast at 8:25 a.m. local time (1:25 p.m. HST). The epicenter was approximately 125-144 km southeast of Petropavlovsk-Kamchatsky at a shallow depth of 19.3-20 km, increasing the potential for tsunami generation.

Russia reported tsunami waves of 3 to 4 meters hitting parts of Kamchatka, with evacuations underway in Severo-Kurilsk. The Pacific Tsunami Warning Center (PTWC) and Japan Meteorological Agency have issued warnings for hazardous tsunami waves, with Japan expecting waves up to 1 meter along its Pacific coast from Hokkaido to Wakayama Prefecture. A tsunami watch was also issued for Hawaii, California, Oregon, Washington, and parts of Alaska, including the Aleutian Islands, with potential wave heights of 1-3 meters in some areas. The watch for Hawaii estimates the earliest wave arrival at 7:17 p.m. HST.

No tsunami warnings are currently in effect for Santa Monica or the broader Southern California coast beyond the watch.[](https://www.theguardian.com/world/live/2025/jul/30/tsunami-alert-pacific-islands-japan-russia-magnitude-8-earthquake-follow-live-updates)[](https://www.indiatoday.in/amp/world/story/tsunami-watch-is-now-in-effect-after-magnitude-8-earthquake-struck-off-russia-us-geological-survey-glbs-2763311-2025-07-30)[](https://www.hindustantimes.com/world-news/us-news/kamchatka-earthquake-hawaii-under-tsunami-watch-as-m8-quake-hits-russias-pacific-coast-101753833099125.html)

The Kamchatka region's seismic activity is due to its location at the convergence of the Pacific and North American tectonic plates, a known seismic hot zone. Earlier this month, on July 20, a magnitude 7.4 earthquake in the same region triggered a brief tsunami alert, but it was lifted with no significant impact.

Authorities urge residents in affected areas to follow evacuation orders and avoid coastal zones. For real-time updates, check tsunami.gov or local emergency services like SMAlerts for Santa Monica. If you're in a tsunami-prone area, move to higher ground immediately if shaking is felt or unusual ocean behavior is observed.
