A magnitude 3.3 earthquake near Ferndale, Humboldt County, California, USA, was reported only 10 minutes ago by the United States Geological Survey (USGS), considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a shallow depth of 12 miles beneath the epicenter around noon on Saturday 9 January 2021 at 1:26 pm local time. 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.3 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ferndale (pop. 1,400) located 16 miles from the epicenter, Scotia (pop. 850) 16 miles away, Fortuna (pop. 12,000) 20 miles away, and Loleta (pop. 780) 21 miles away. In Eureka (pop. 27,000, 33 miles away), Bayside (pop. 17,100, 37 miles away), Arcata (pop. 17,800, 38 miles away), and McKinleyville (pop. 15,200, 43 miles away), the quake was probably not felt.
