Small magnitude 3.2 earthquake 40 miles southwest of Eureka, California, United States
3.2 quake 21 Oct 6:10 am (GMT -7)

A shallow magnitude 3.2 earthquake was reported early morning near Eureka, Humboldt County, California, USA.
According to the United States Geological Survey, the quake hit on Thursday, October 21st, 2021, at 6:10 am local time at a shallow depth of 12 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.2 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, 23 miles away), Rio Dell (pop. 3,400, 25 miles away), Hydesville (pop. 1,200, 28 miles away), Fortuna (pop. 12,000, 28 miles away), Eureka (pop. 27,000, 40 miles away), Bayside (pop. 17,100, 45 miles away), and Uniontown (pop. 17,800, 46 miles away), the quake was probably not felt.
