Update Wed, 24 Nov 2021, 10:30Magnitude 3.0 earthquake strikes near McAlester, Pittsburg County, Oklahoma, USA
3.0 quake 24 Nov 4:16 am (GMT -6)
The United States Geological Survey reported a magnitude 3.0 quake in the United States near McAlester, Pittsburg County, Oklahoma, only 14 minutes ago. The earthquake hit early morning on Wednesday, November 24th, 2021, at 4:16 am local time at a very shallow depth of 3.1 miles. 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 Quinton (pop. 1000) located 2 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Wilburton (pop. 2,700) located 13 miles from the epicenter. In Stigler (pop. 2,800, 18 miles away), McAlester (pop. 18,300, 25 miles away), Henryetta (pop. 5,800, 42 miles away), Sallisaw (pop. 8,600, 42 miles away), Poteau (pop. 8,700, 43 miles away), and Muskogee (pop. 38,500, 45 miles away), the quake was probably not felt.
