Evacuations were initiated in several coastal communities in Northern California following a magnitude-7.0 earthquake that struck offshore, prompting a tsunami warning affecting millions across parts of California and Oregon. The powerful quake occurred at 10:44 a.m. and was located approximately 30 miles west of Petrolia in Humboldt County, according to the U.S. Geological Survey.
Initially recorded at a magnitude of 6.0, the earthquake was upgraded to 7.0 as it caused widespread shaking not only along the coast but also in some inland areas. The tsunami warning, which impacted regions from Davenport, California, in Santa Cruz County to the Oregon border, was lifted around noon, though evacuation orders remained in effect for some communities, and BART service was temporarily halted.
A tsunami warning signifies imminent or expected widespread flooding, as detailed by the National Weather Service, which also noted risks of powerful currents and coastal flooding. Fortunately, NOAA’s tsunami warning coordinator David Snider stated that the quake did not produce a destructive wave, reassuring residents that the potential for widespread damage from a tsunami was minimal. However, he mentioned residents should expect stronger currents and waves in the hours following the earthquake.
Reports of minor to moderate shaking came in from various locations, including Half Moon Bay, San Francisco, and Sacramento. Local business owner Julie Kreitzer shared her experience, noting that while her store sustained some mess, she was safe. Humboldt County officials have started assessing damage reports, which include broken water mains and structural issues.
The California Geological Survey highlighted that the state’s coastline has experienced over 150 tsunamis since 1800, with most being minor and causing limited damage. While some historic events, like the 1964 tsunami in Crescent City triggered by an Alaskan earthquake, resulted in significant destruction and loss of life, the current earthquake might serve as a reminder of the importance of preparedness.
In light of the situation, Governor Gavin Newsom was briefed on the earthquake and emphasized the need for readiness for such events, which, while not frequent, occur often enough to warrant awareness among residents.
Amidst these concerns, it’s vital to acknowledge the resilience of communities and local emergency services as they respond and adapt to natural events. This occurrence serves as a powerful reminder of nature’s unpredictability but also highlights the importance of preparedness and community support in times of crisis.
In conclusion, while Northern California faced challenges following the earthquake, the response from local authorities and the community’s preparedness offer a hopeful outlook for managing future seismic events.
