Magnitude 3.0 earthquake strikes near Cedar City, Iron County, Utah, USA
3.0 quake 7 Apr 11:45 pm (GMT -6)
3.0 quake 7 Apr 11:45 pm (GMT -6)
A magnitude 3.0 earthquake near Cedar City, Iron County, Utah, USA, was reported only 30 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 1.2 miles beneath the epicenter late at night on Wednesday 7 April 2021 at 11:45 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.0 earthquake 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 Summit (pop. 160) located 2 miles from the epicenter, and Enoch (pop. 6,300) 4 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Louisa (pop. 2,900) located 8 miles from the epicenter, and Cedar City (pop. 30,200) 9 miles away. In Hurricane (pop. 15,500, 46 miles away), the quake was probably not felt.
