A magnitude 3.9 earthquake near Lone Pine, Inyo County, California, USA, was reported only 55 seconds ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 5 miles beneath the epicenter in the morning on Friday, August 21st, 2026, at 10:26 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.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 Keeler (pop. 66) located 7 miles from the epicenter, and Lone Pine (pop. 2,000) 12 miles away.Earthquake data: Date & time: Aug 21, 2026 10:26 am (Los Angeles time) local time (21 Aug 2026 17:26 GMT)Magnitude: 3.9Depth: 8.00 kmEpicenter latitude / longitude: 36.59°N / 117.85°W (Inyo County, California, United States)Primary data source: USGS
