Tsunami Warning Issued for Northern California
Late Thursday morning, a powerful earthquake with a preliminary magnitude of 7.0 struck roughly 60 miles offshore from Ferndale, in Humboldt County, California, according to the United States Geological Survey (USGS). The quake, occurring at a depth of 12 miles beneath the ocean floor, sent tremors through much of Northern California, alarming residents and prompting immediate action from authorities.
In the wake of the earthquake, the National Weather Service (NWS) issued a tsunami warning for coastal areas, advising Californians to “get away from coastal waters.”
Tsunami Warning and Projected Impact Times
The tsunami warning applies to much of the Northern California coastline, where waves generated by the earthquake could pose significant risks. Coastal residents are being urged to evacuate to higher ground immediately and avoid beaches, harbors, and marinas until the warning is lifted.
The National Weather Service has provided the following timing for when tsunami impacts might be observed:
- Crescent City: First waves expected around 11:15 AM
- Eureka: First waves expected around 11:25 AM
- San Francisco Bay Area: Potential impacts around 11:45 AM
Officials stress that even small tsunami waves can carry dangerous currents and the potential for significant flooding in low-lying areas.
Community Impact and Response
Ferndale and nearby towns reported noticeable shaking, with some residents describing items falling from shelves and minor structural damage to older buildings. While no injuries have been reported yet, emergency services are conducting assessments and assisting with precautionary evacuations along the coastline.
Local power outages have been reported in Humboldt County, and authorities are urging residents to avoid using phones for non-emergency purposes to keep lines clear for first responders.
Preparedness Measures
The California Office of Emergency Services (Cal OES) is coordinating with local authorities to provide resources and facilitate evacuations. Residents are being advised to:
- Follow all evacuation orders and head to designated safe zones.
- Stay tuned to official updates through NOAA Weather Radio, the NWS, or local emergency channels.
- Avoid returning to coastal areas until an official “all-clear” has been given.
Seismologist Insights
Experts from the USGS noted that the quake occurred along the Mendocino Triple Junction, a seismically active area where three tectonic plates meet. Dr. Linda Parker, a geophysicist with the USGS, stated, “This region is no stranger to earthquakes, but any event of this magnitude warrants close attention for potential aftershocks or additional seismic activity.”
Next Steps
As this is a developing situation, updates on the tsunami’s potential impacts and the earthquake’s aftereffects will continue to be provided by authorities. Residents are urged to remain alert and prioritize their safety by adhering to official guidance.
