Small magnitude 3.5 quake hits 15 miles northwest of Brawley, California, United States in the afternoon
3.5 quake 9 Feb 5:27 pm (GMT -8)
3.5 quake 9 Feb 5:27 pm (GMT -8)
A magnitude 3.5 earthquake near Brawley, Imperial County, California, USA, was reported only 6 minutes 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 2.1 miles beneath the epicenter in the afternoon on Tuesday 9 February 2021 at 5:27 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.
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 Calipatria (pop. 7,400) located 7 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Brawley (pop. 25,900) located 15 miles from the epicenter, Imperial (pop. 17,100) 23 miles away, and El Centro (pop. 44,000) 27 miles away. In Calexico (pop. 40,100, 35 miles away), Coachella (pop. 44,600, 47 miles away), and Indio (pop. 87,500, 51 miles away), the quake was probably not felt.
