Just 7 minutes ago, a 3.0-magnitude earthquake struck near Eureka, Humboldt County, California, USA. The tremor was recorded in the morning on Thursday 4 March 2021 at 9:08 am local time, at a shallow depth of 13 miles below the surface.
The event was filed by the United States Geological Survey, the first seismological agency to report it.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.0 as well.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Ferndale (pop. 1,400, 24 miles away), Rio Dell (pop. 3,400, 26 miles away), Fortuna (pop. 12,000, 29 miles away), Humboldt Hill (pop. 3,400, 35 miles away), Eureka (pop. 27,000, 40 miles away), Bayside (pop. 17,100, 45 miles away), and Arcata (pop. 17,800, 46 miles away), the quake was probably not felt.
