Small earthquake of magnitude 3.5 just reported 7 miles east of El Centro, California, United States

3.5 quake 10 Apr 6:22 am (GMT -7)
A shallow magnitude 3.5 earthquake was reported early morning near El Centro, Imperial County, California, USA.
According to the United States Geological Survey, the quake hit on Saturday 10 April 2021 at 6:22 am local time at a shallow depth of 7.8 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.5 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 Holtville (pop. 6,400) located 4 miles from the epicenter, Heber (pop. 4,300) 6 miles away, and El Centro (pop. 44,000) 7 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Calexico (pop. 40,100) located 7 miles from the epicenter, Imperial (pop. 17,100) 9 miles away, Mexicali (pop. 689,800) 10 miles away, Santa Isabel (pop. 29,300) 12 miles away, Brawley (pop. 25,900) 15 miles away, and Puebla (pop. 15,200) 15 miles away.
