A tsunami warning along the California coastline was canceled after a powerful 7.0 magnitude earthquake near Eureka. The early warning advised residents to evacuate coastal areas, affecting around five million people. The earthquake prompted several aftershocks but ultimately, the tsunami threat was deemed to have passed after a brief period of concern.
On Thursday, the National Weather Service lifted a tsunami warning affecting a significant portion of the California coastline after determining that the threat had subsided following a powerful earthquake near Eureka. The warning, which activated alarms on residents’ mobile devices at 10:50 a.m., advised individuals to evacuate coastal areas and seek higher ground, covering regions from southern Oregon to the Bay Area and extending down to Davenport, located just north of Santa Cruz.
The tsunami alert was prompted by an earthquake striking approximately 40 miles southwest of Ferndale, Humboldt County, which the United States Geological Survey initially rated at a magnitude of 7.0, subject to potential revisions in the ensuing hours. “It started out shaky and then turned into a rolling one,” recounted local resident Katie Hall. Multiple aftershocks were reported subsequent to the initial quake, increasing public concern.
The National Weather Service had estimated the onset of potential tsunami activity could occur between 11:10 a.m. and 12:40 p.m. However, by 11:30 a.m., the agency announced that no further action was required and urged the public to remain cautious when near maritime zones. During the time the alert was active, approximately five million residents faced the tsunami warning.
Tsunamis are typically caused by underwater earthquakes, which can displace water and generate large waves capable of travelling significant distances. The Pacific coast is particularly vulnerable due to its proximity to tectonic plate boundaries where such seismic activities frequently occur. Earthquakes of magnitude 7.0 or greater are classified as major and can lead to widespread damage and tsunami activity, prompting timely warnings to ensure public safety.
In summary, the prompt action taken by the National Weather Service in canceling the tsunami warning underscores the effectiveness of seismic monitoring systems in California. Residents were urged to evacuate to safety during the initial alert, demonstrating the critical need for preparedness in earthquake-prone regions. Fortunately, the tsunami threat was eliminated without incident, allowing residents to resume normal activities shortly thereafter.
