Small tremor of magnitude 3.1 just reported 21 miles southwest of Norman, Oklahoma, United States

A very shallow magnitude 3.1 earthquake was reported early morning near Norman, Cleveland County, Oklahoma, USA.
According to the United States Geological Survey, the quake hit on Sunday 14 March 2021 at 6:00 am local time at a very shallow depth of 0.4 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 2.9 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.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Blanchard (pop. 8,300) located 10 miles from the epicenter, and Chickasha (pop. 16,500) 16 miles away. In 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), Midwest City (pop. 57,200, 35 miles away), and Edmond (pop. 90,100, 47 miles away), the quake was probably not felt.
