Small magnitude 3.7 earthquake 23 miles southeast of Apple Valley, California, United States

An earthquake of magnitude 3.7 occurred only 4 minutes ago 23 miles southeast of Apple Valley, California, United States, the United States Geological Survey reported.
The quake hit at a very shallow depth of 3.8 miles beneath the epicenter near Apple Valley, San Bernardino County, California, USA, early morning on Sunday, October 5th, 2025, at 3:41 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.7 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.7.
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 Big Bear City (pop. 12,300) located 4 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Apple Valley (pop. 72,200) located 23 miles from the epicenter, Yucaipa (pop. 53,300) 23 miles away, Highland (pop. 54,900) 24 miles away, Redlands (pop. 71,000) 26 miles away, Hesperia (pop. 93,300) 26 miles away, San Bernardino (pop. 216,100) 29 miles away, Victorville (pop. 122,200) 29 miles away, and Riverside (pop. 322,400) 40 miles away.
