An earthquake of magnitude 3.4 occurred only 12 minutes ago 19 miles northeast of McAlester, Oklahoma, United States, the United States Geological Survey reported.
The quake hit at a very shallow depth of 3.1 miles beneath the epicenter near McAlester, Pittsburg County, Oklahoma, USA, early morning on Saturday, May 28th, 2022, at 6:39 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 3.4 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.4.
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 7 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Longtown (pop. 2,700) located 11 miles from the epicenter, North Fork Town (pop. 2,900) 15 miles away, Wilburton (pop. 2,700) 16 miles away, Krebs (pop. 2,000) 17 miles away, McAlester (pop. 18,300) 19 miles away, and Stigler (pop. 2,800) 24 miles away. In Okmulgee (pop. 12,200, 45 miles away), and Muskogee (pop. 38,500, 46 miles away), the quake was probably not felt.

If you felt this quake (or if you were near the epicenter), please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
