Small magnitude 3.6 quake hits 42 miles southeast of Eureka, California, United States in the afternoon

An earthquake of magnitude 3.6 occurred in the afternoon on Saturday, December 28th, 2024, at 4:21 pm local time near Eureka, Humboldt County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 3.9 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.6 earthquake as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Mad River (pop. 420) located 1 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Hayfork (pop. 2,400) located 18 miles from the epicenter, Rio Dell (pop. 3,400) 32 miles away, and Fortuna (pop. 12,000) 36 miles away. In Bayside (pop. 17,100, 39 miles away), Arcata (pop. 17,800, 41 miles away), Eureka (pop. 27,000, 42 miles away), and McKinleyville (pop. 15,200, 46 miles away), the quake was probably not felt.
