8.8-Magnitude Earthquake
America’s West Coast Sees Tsunami Impact As Alerts Downgrade
Published
Tsunami waves have crashed on the shorelines of Hawaii, California, and Washington after a massive 8.8-magnitude earthquake struck Russia’s far eastern coast, but fortunately, the impact has been minimal.
Alerts were issued overnight across the Pacific as coastal regions prepared for potential impact, with Hawaii initially bracing for significant damage. Residents were evacuated, and airports were temporarily closed to facilitate the evacuation process.
Fortunately, the alert level was downgraded to a tsunami advisory just before 5 AM ET, allowing evacuated residents to return to their homes safely.
Gov. Josh Green said so far no damage has been recorded as tsunami waves reached Oahu, Hawaii’s most populous island, but it will take hours of observation before authorities can determine whether the event has passed.

Hawaii Gov. Josh Green reported earlier on Wednesday that while significant water was received, no damage has been recorded on Oahu, Hawaii’s most populous island. However, authorities are continuing to monitor the situation closely.
Meanwhile, the West Coast of mainland America has experienced waves measuring just under 4 feet, prompting residents to avoid beaches and harbors as a precaution.
As of Wednesday morning, a tsunami warning remains in effect for a 40-mile stretch of the Northern California coastline, extending just south of Klamath to the Oregon border.
Despite the relatively mild impact, Dr. Ariel Cohen, head meteorologist at the National Weather Service’s Los Angeles/Oxnard office, advises the public to remain cautious as there have been reports of significant water surges, especially along west- and northwest-facing beaches.
Russia experienced tsunami waves exceeding 13 feet off the coast of Kamchatka, where the earthquake originated, according to state media.
Nearly 2 million people were evacuated from Japan as the island nation prepared for the potential surge. Fortunately, no fatalities have been reported as of Wednesday morning.
