Minor Tremor Near Petrolia: No Damage Reported
26 May
Summary
- A 3.2 magnitude earthquake occurred 18 miles off the coast of Petrolia.
- The tremor struck in the seismically active Lost Coast area of California.
- This event follows a swarm of quakes in May 2025 and a larger one in December 2025.

A magnitude 3.2 earthquake was recorded offshore Northern California on Monday morning. The seismic event occurred approximately 18 miles west of Petrolia, striking at 6:53 a.m. PT. This region, known as the Lost Coast, is characterized by its rugged terrain and seismic activity.
While Monday's tremor registered a magnitude of 3.2, the area has a history of more significant seismic events. In May 2025, a swarm of earthquakes occurred off Humboldt County, with the largest reaching a magnitude of 4.6. The following December 2025, a powerful 6.4-magnitude quake struck near Eureka, causing damage to homes and widespread power outages.
Despite the historical context and proximity to previous significant seismic activity, the 3.2-magnitude event on Monday did not result in any reported damage. Residents in Petrolia and surrounding coastal communities can take comfort in the lack of impact from this particular tremor, though the region's seismic past warrants continued attention.
