A series of earthquakes struck Northern California on Thursday, highlighted by a significant magnitude-7.0 tremor occurring offshore in the Pacific Ocean at 10:44 a.m. PT. This seismic activity triggered a tsunami warning for coastal regions extending from Santa Cruz to parts of Oregon, but the warning was lifted shortly before noon PT.

In addition to the major quake, two smaller earthquakes were also recorded near the same time: a preliminary 6.0 magnitude quake in Humboldt County, which was later downgraded to 4.7, and a 5.8 magnitude earthquake in Cobb, Lake County, which was revised to 4.1.

Seismologists reported at least 72 aftershocks since the initial earthquake, with expectations of more to follow. The primary quake occurred near the Mendocino Triple Junction, recognized for its high seismic activity.

In response to the earthquake’s impact, Governor Gavin Newsom announced a state emergency declaration to provide additional resources to the affected counties of Mendocino, Humboldt, and Del Norte. While there was an alarming tsunami warning, NOAA officials later determined that the risk of a dangerous tsunami hitting the West Coast was minimal.

Residents in Northern California experienced the aftermath of the tremors, with businesses like a Shop Smart in Redway suffering water damage, prompting closures. In Half Moon Bay, some residents expressed confusion at the lack of sirens, despite receiving tsunami alerts on their mobile devices.

Teachers and students in Eureka practiced safety drills in preparation for such emergencies, and while the quake was startling, the experience ultimately reinforced community preparedness.

This series of events highlights the resilience of Northern California communities in the face of seismic challenges, ensuring that local residents remain alert and prepared for future earthquakes. While the day was undoubtedly tumultuous, the quick response from emergency services and the guidance from state officials signify a commitment to safety and preparedness in the region. It’s promising to see communities coming together with a renewed focus on earthquake readiness.

Summary: Northern California experienced multiple earthquakes, including a magnitude-7.0 offshore quake, leading to a temporary tsunami warning that was later canceled. The state has declared an emergency to assist affected areas, and residents are assessing damage and reflecting on their preparedness for such events.
