Small magnitude 3.6 earthquake 6 miles southeast of Ontario, California, United States

3.6 quake 3 Sep 10:04 am (GMT -7)
3.6 quake 3 Sep 10:04 am (GMT -7)
An earthquake of magnitude 3.6 occurred only 7 minutes ago 6 miles southeast of Ontario, California, United States, the United States Geological Survey reported.
The quake hit at a shallow depth of 7 miles beneath the epicenter near Ontario, San Bernardino County, California, USA, in the morning on Saturday, September 3rd, 2022, at 10:04 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 4.1 earthquake.
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 Jurupa Valley (pop. 21,900) located 3 miles from the epicenter, Eastvale (pop. 59,000) 4 miles away, Ontario (pop. 171,200) 6 miles away, Rancho Cucamonga (pop. 175,200) 6 miles away, Upland (pop. 76,400) 7 miles away, Chino (pop. 85,600) 8 miles away, and Fontana (pop. 207,500) 8 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Corona (pop. 164,200) located 10 miles from the epicenter, and Anaheim (pop. 350,700) 24 miles away.
