3.6 quake 15 Apr 9:26 am (GMT -5)

A magnitude 3.6 earthquake near Norman, Cleveland County, Oklahoma, USA, was reported only 12 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 0.3 miles beneath the epicenter in the morning on Thursday 15 April 2021 at 9:26 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 3.4 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 Dibble (pop. 830) located 4 miles from the epicenter, and Blanchard (pop. 8,300) 10 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Chickasha (pop. 16,500) located 15 miles from the epicenter, Norman (pop. 120,300) 21 miles away, Moore (pop. 60,500) 26 miles away, Mustang (pop. 20,200) 27 miles away, Oklahoma City (pop. 631,300) 34 miles away, and Midwest City (pop. 57,200) 35 miles away. In Edmond (pop. 90,100, 47 miles away), and Lawton (pop. 96,700, 48 miles away), the quake was probably not felt.
