We felt it too. Arkansas, just west of Memphis.
Interesting.
My tinnitus had a definite screech about then or maybe a little before.
Didn't feel anything here.

There was a pretty good M 3.7 #earthquake northwest of Poplar Bluff, MO tonight around 9:53pm ET /8:53 pm CT. Lots of reports of people feeling it in the New Madrid seismic zone.

Didn't feel anything west of there, in Douglas County, but then again that's a pretty small tremor.
Slippage along a fault line is the fault doing some stress relief, which is a good thing. When it's been slipping along and stops for a long time, that's worrisome. Stress is then building up along the fault and the big quakes happen when it builds up and whatever had it hung up suddenly can't contain it anymore.

Neither here nor there.
This explains the headache and Jr. barking at nothing.

Everyone who did feel it or noticed shaking needs to go to the USGS site to report it. It helps them get a much better understanding of the quake and the area.

That's way too close to home.

oh no…last thing we need now is awakened New Madrid fault…Paleoseismic evidence collected in recent decades indicates strong "earthquake triplets" similar in magnitude to 1811-12 temblors have occurred ~ every 500 years along the New Madrid fault and are likely to happen again.

central Mississippi Valley is most earthquake-prone region of US east of Rocky Mrs. Most quakes in the area are relatively small & occur w/in 100-mile-long New Madrid seismic zone that extends along Mississippi fr Missouri to Arkansas…
during winter of 1811 to 1812, New Madrid, Mo area was jolted by a series of three powerful earthquakes now estimated to have been of magnitude 7.5 to 8.3. quakes caused church bells to ring thousand miles away in Boston & changed the course of the Mississippi River…
in geology 101 one may be thought EQs coming i n triplets, as was the case during 1811-1812 is an oddity? perhaps, perhaps not in case of New Madrid active zone. different fault than those marking boundaries btwn two tectonic plates. as they grained past one another you get EQs…
geologists aren’t sure when next New Madrid EQ going to ring up bells in Boston.~5% of EQs take place w/in a plate, like New Madrid & r called intraplate as opposed to majority of EQs occurring near plate boundaries called interplate,like San Andreas Fault, aka transform fault… intraplate EQs are caused by stresses w/in a plate. since plates move over a spherical surface, zones of weakness are created. intraplate EQs happen along these zones of weakness. hardly mappable since they are below overlying sediments, New Madrid fault zone historical EQs

Friend in mountain home, AR felt it. Said her whole house shook a little.

Title of this thread mentions SW Missouri, but then on the map posted, it looks to me like this quake happened in SE Missouri.

Yep posting from South West MO I posted before USGS had it up so I didn’t know location.
Updated thread title to indicate correct location for posterity. Digital archeologists may comb through bazillions of pages to write future documentaries.

LYKURGOS, I'm sure posterity will be ever so grateful!
This comment of yours has made me smile so much my cheeks are starting to hurt! Good one!
