An earthquake of magnitude 3.0 occurred early morning on Friday 25 December 2020 at 3:55 am local time near Fortuna, Humboldt County, California, USA, as reported by the United States Geological Survey (USGS).
According to preliminary data, the quake was located 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 3.0 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 Scotia (pop. 850, 20 miles away), Ferndale (pop. 1,400, 21 miles away), Fortuna (pop. 12,000, 25 miles away), Loleta (pop. 780, 26 miles away), Eureka (pop. 27,000, 38 miles away), Bayside (pop. 17,100, 42 miles away), and Arcata (pop. 17,800, 43 miles away), the quake was probably not felt.

Fortuna, CA / Light shaking (MMI IV) / rattling, vibrating / 2-5 s : Sitting in a fifth wheel trailer. It’s a windy humid morning, has been stormy all evening. Noticed the trailer was sort of vibrating rather than the bumps from the wind. Once I realized that it was still vibrating I looked up and around the room. Within 5 seconds or so it ended. I got online to see if it was an earthquake and found this site. It had been 3 minutes. | 2 users found this interesting.  
Laytonville, California (61.7 km ESE of epicenter) [Map] / Very weak shaking (MMI II) / 10-15 s : Felt a rumble for about 8-10 seconds, could have been thunder but felt like the ground shaking and noise like thunder.
