A magnitude 4.3 earthquake near Sikeston, Scott County, Missouri, USA, was reported only 14 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 0.9 miles beneath the epicenter in the evening on Tuesday, September 7th, 2021, at 8:52 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 4.2 earthquake.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Bloomfield (pop. 1,900) located 6 miles from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Dexter (pop. 8,000) located 11 miles from the epicenter, Bernie (pop. 2,000) 20 miles away, Sikeston (pop. 16,400) 24 miles away, Poplar Bluff (pop. 17,300) 26 miles away, and Malden (pop. 4,100) 28 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Jackson (pop. 14,900) located 35 miles from the epicenter, and Cape Girardeau (pop. 39,500) 36 miles away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
