A powerful earthquake struck off the coast of Northern California on Thursday morning, sending tremors through communities and triggering tsunami warnings for millions of residents. The magnitude 7.0 earthquake, initially reported as a 6.6, hit at approximately 10:55 a.m. local time, roughly 63 kilometers (39 miles) offshore near the historic town of Ferndale in Humboldt County.
The quake’s impact was felt as far south as San Francisco, over 418 kilometers (260 miles) away. The U.S. National Weather Service (NWS) issued tsunami warnings for a vast stretch of the California and Oregon coastlines, encompassing an estimated 4.7 million people.
“The governor is meeting with state emergency officials and working to ensure Californians are safe,” the office of California Governor Gavin Newsom announced on social media.
The NWS initially projected the tsunami to reach the California coast around 8 p.m. Eastern Time, but later canceled the warning. While the earthquake’s depth of 10 kilometers (6.2 miles) mitigated the risk of widespread devastation, the USGS issued a “yellow alert,” indicating the possibility of localized damage.
“Some damage is possible and the impact shoudl be relatively localized,” the USGS stated.
Early reports from the USGS suggested that tens of thousands of people felt the earthquake’s tremors. In Humboldt County, approximately 19,000 customers experienced power outages, a critically important increase from pre-earthquake levels, according to data from poweroutage.us.
The City of Berkeley, located across the bay from San Francisco, issued an evacuation order for certain coastal areas due to the tsunami threat. “Due to a tsunami coming to West Berkeley,” an alert sent to residents stated.
As of Thursday afternoon, no immediate reports of significant damage had emerged.

A magnitude 7.0 earthquake struck off the coast of Northern California on Thursday morning, sending tremors as far south as San Francisco and prompting tsunami warnings for millions of residents. While the depth of the earthquake mitigated the risk of widespread devastation,the event caused power outages and prompted evacuations in coastal communities.
The earthquake,initially reported as a 6.6 magnitude, hit at approximately 10:55 a.m. local time,roughly 63 kilometers (39 miles) offshore near Ferndale in Humboldt County. The U.S. National weather Service (NWS) issued tsunami warnings for a large portion of the California and Oregon coastlines,encompassing an estimated 4.7 million peopel.
To better understand the impact of this event, we spoke with seismology expert Dr. Emily Carter from the California Institute of Technology and disaster preparedness specialist Sarah Jensen from the American Red Cross.
Immediate Impact and Safety Measures
WTN: Dr. carter, what can you tell us about the initial impact of this earthquake?
“The magnitude 7.0 earthquake is significant, especially considering its location fairly close to the coastline. the depth of 10 kilometers (6.2 miles) played a role in reducing the intensity of shaking felt inland, but the proximity to populated areas, including Ferndale, likely resulted in some localized damage.”
– Dr. Emily Carter, Seismology Expert, Caltech
WTN: Sarah, what are the immediate steps people in affected areas should take?
“The most critically important thing right now is to heed official warnings and instructions from local authorities. If you’re in a coastal area under a tsunami warning, evacuate to higher ground instantly. Have an emergency kit prepared with essentials like water,food,and a first-aid kit.”
– Sarah Jensen, Disaster Preparedness Specialist, American Red Cross
Tsunami Risk and Coastline Vulnerability
WTN: Dr. Carter, how reliable are the tsunami warning systems in place, and what factors influence tsunami risk?**
” Our tsunami warning systems have been greatly improved over the years, and they’re designed to provide crucial time for evacuation. Factors like the earthquake’s magnitude, depth, and location all contribute to tsunami risk. Coastal geography and topography also play a significant role in determining the impact of a tsunami.”
– Dr.Emily Carter, Seismology Expert, Caltech
**WTN: Sarah, what are some of the long-term challenges faced by communities in tsunami-prone areas?**
“Coastal communities face ongoing challenges like infrastructure vulnerability, economic disruption, and the need for ongoing education and awareness about tsunami preparedness. Building resilient communities means investing in infrastructure that can withstand these events and empowering individuals with the knowledge to protect themselves.”
– Sarah Jensen, Disaster Preparedness Specialist, American Red Cross
Looking Ahead: Preparedness and Resilience
WTN: Dr. Carter, what can we learn from this earthquake to improve earthquake preparedness in California?**
“This event highlights the importance of ongoing earthquake research, infrastructure improvement, and public education. California has made significant strides in these areas, but events like this underscore the need for continuous vigilance and innovation.”
– Dr. Emily Carter, Seismology Expert, Caltech
WTN: Sarah, what advise do you have for our readers on preparing for future earthquakes and natural disasters?**
“The key is to be prepared.Develop a family emergency plan, assemble an emergency kit, secure your home, and stay informed about potential hazards in your area. Remember, preparedness can save lives.”
– Sarah Jensen, disaster Preparedness Specialist, American Red Cross
