Small magnitude 3.3 quake hits 14 miles southwest of Clearlake, California, United States early morning
3.3 quake 29 Jan 5:00 am (GMT -8)
3.3 quake 29 Jan 5:00 am (GMT -8)
An earthquake of magnitude 3.3 occurred only 6 minutes ago 14 miles southwest of Clearlake, California, United States, the United States Geological Survey (USGS) reported.
The quake hit at a very shallow depth of 2.4 miles beneath the epicenter near Clearlake, Lake County, California, USA, early morning on Friday 29 January 2021 at 5:00 am 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.
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 Kelseyville (pop. 3,400) located 5 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tuckertown (pop. 4,800) located 9 miles from the epicenter, Clearlake (pop. 15,200) 14 miles away, and Ukiah (pop. 15,900) 24 miles away. In Santa Rosa (pop. 175,000, 34 miles away), the quake was probably not felt.
