SECOND UPDATE: Tsunami Advisory is Now Lifted (with Video)



The tsunami advisory for Humboldt County has been lifted.


The tsunami advisory remains in place for Humboldt County due to last night's volcanic explosion near the Tonga Islands.

“For your safety, stay away from beaches and low-lying coastal areas until emergency officials indicate it is safe. DO NOT GO TO THE SHORE TO VIEW THE TSUNAMI. Hazardous waves may continue for several hours.,” a 10 a.m. update from the Humboldt County Office of Emergency Services states.

The Redwood Coast Tsunami Work Group reports that the peak height at Crescent City recorded so far (as of about 10 a.m.) was 20 inches and just under 3 feet at Arena Cove. View the Crescent City Harbor cam here.

"The tsunami advisory is still in place and everyone needs to stay off the beach, perhaps for the rest of the day," the group's post states.
According to a city of Eureka news release, after receiving notification of the advisory, staff went to the Eureka Boat Basin in the early morning hours to notify residents living on their boats and advised them to leave. People found camping in their vehicles at the Samoa Boat ramp or other harbor areas were also notified, the release states.

"All docks and ramps were closed and are expected to remain closed until an 'all clear' advisory is issued," the city's release states. "A slight surge was noticed in the harbor area around 8 a.m .and staff continues to monitor the area for additional surges. Surges which could be dangerous can happen many hours after the first wave arrival. The first tsunami wave or surge may not be the highest in the series."


The National Weather Service has issued a tsunami advisory for the West Coast due to seismic activity near Tonga last night. While no evacuation is called for, an alert message from the Humboldt County Office of Emergency Services warns local residents to "stay away from beaches and low lying coastal areas, avoid boating and fishing for the next several hours."

According to the National Weather Service's Eureka office's Facebook page, waves may reach heights of 1 to 3 feet, and "strong rip currents and coastal flooding" are expected.

The Redwood Coast Tsunami Working Group reports the tsunami surge locally is “modest” but arriving near high tide with high surg.

“Do not go to the coast to watch,” the group warns on its Facebook page. “You are unlikely to see anything of interest but the combination of storm waves and tsunamis could cause sudden unexpected surges along the beach.”
