3.8 quake 16 Jan 7:14 pm (GMT -8)
A magnitude 3.8 earthquake near Porterville, Tulare County, California, USA, was reported only 9 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 very shallow depth of 0.9 miles beneath the epicenter early evening on Saturday 16 January 2021 at 7:14 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 3.8 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 Olancha (pop. 190) located 8 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Lone Pine (pop. 2,000) located 29 miles from the epicenter, and Ridgecrest (pop. 28,800) 46 miles away. In Porterville (pop. 56,100, 52 miles away), the quake was probably not felt.
