A tsunami advisory remains in effect for coastal communities from the Humboldt/Del Norte line to the Oregon border following a massive offshore earthquake. Authorities have warned of dangerous waves and strong currents that could threaten residents and visitors in the affected areas.
The advisory was triggered by a powerful 8.8 magnitude earthquake that struck 80 miles southeast of Petropavlovsk Kamchatka, Russia, at 4:25 p.m. PDT on July 29. The earthquake’s impact led to concerns over potential tsunami waves hitting the coast. While widespread coastal flooding is not expected, strong currents and unpredictable waves remain a danger through Thursday morning.
Local Impact and Safety Precautions
Communities in Del Norte and Humboldt counties, including Crescent City and surrounding coastal areas, are experiencing the most severe impacts. Authorities are urging residents and visitors to stay off beaches, avoid harbors and marinas, and remain vigilant as tsunami waves may continue for several hours after the first wave arrives.
Officials remind the public that the first wave is rarely the largest, and tsunami waves can arrive in multiple surges, each posing its own risk. Authorities strongly advise keeping mobile devices charged, monitoring local emergency alerts, and being ready to evacuate if necessary.
Patrols and Evacuation Readiness
Harbormasters and law enforcement are actively patrolling key areas, including Highway 101 and harbor districts, to ensure public safety. Authorities are also prepared to issue evacuation orders should conditions worsen.
The tsunami advisory remains in effect until further notice, and residents are encouraged to stay informed through tsunami.gov and local emergency channels for real-time updates.
