My wife and I just felt a very noticeable earthquake.
Was that what that was? I thought it was someone stomping through the house...
I would have guessed closer to 6.

Wabash Valley Seismic Zone
Recent studies have indicated that the New Madrid Seismic Zone is not the only ‘hot spot’ for earthquakes in the Central United States. On June 18, 2002, a 5.0 magnitude earthquake struck the Evansville, Indiana with an epicenter between Mt. Vernon and West Franklin in Posey County, in an area that is part of the Wabash Valley Seismic Zone. According to the Indiana University Indiana Geological Survey, while there was minor damage associated with the earthquake, the tremor was a warning to residents of the Wabash Valley Seismic Zone that earthquakes can, and do, strike close to home.
The Wabash Valley Seismic Zone is located in Southeastern Illinois and Southwestern Indiana and it is capable of producing ‘New Madrid’ size earthquake events. Since the discovery of this seismic zone, earthquake awareness and preparedness have increased. Residents are seeing that moderate sized earthquakes are not just occuring to south, but occur right at home and can affect Illinois, Indiana, and Kentucky.
Geologists in Indiana and Illinois have found liquefaction sites and sand dikes that shows the evidence of prehistoric earthquakes in the region. By examining the size of the dikes and sediment found within the sand dikes, geologists are able to estimate the size of the earthquake it took to create the formations. In the mid-1980’s, geologist Steven Obermeier found a liquefaction formation that was estimated, through carbon dating, to be 6,100 years old. The earthquake that produced the site was estimated to be a magnitude 7.0, large enough to seriously disrupt the area known as the Wabash Valley Seismic Zone.
Current research is still turning out new evidence of historic earthquakes in the zone. For further informaiton, browse through the links to the right.
I felt about 8 sways.
This is the same Indiana fault that shifted a couple years ago.
This is the strongest one I have ever felt here in SW Illinois and I am on the New Madrid Fault.
This quake appears to be north of the New Madrid Seismic Zone - but it’s close enough.
Quake energy propagates really easily in the midwest.
The National Weather Service Office in Paducah had had reports of items being knocked off walls in the Poseyville area.Police dispatch in Evansville reported the investigation of a possible gas leak on Bayard Bark Drive near Kerth. More information will be posted as it becomes available.
120 miles east of St. Louis and about 40 miles west of Evanville IL
It was probably closer to ‘86, that’s the last one I felt. Folks thought I was crazy it was so light in our area at the time.
This one woke me from a sound sleep. I’d fallen asleep on the couch. At first I thought it was one of the neighborhood idiot children with their stereo. Until I realized: no music. So I ran to tell hubby, who promptly declared me crazy and went back to sleep.
To him I say, “HA!”
Woke me up here in St. Matthews, Louisville...
ping
...Oh it is another fault line, one I did not know about.
Felt it up here in Muncie too...
This has to be the Indiana Fault, (don’t recall the name right now) the same one that produce a good shaker 3.9 a couple years ago.
I was getting in the shower. It moved the sliding door going out to the deck!
Interesting for the first time in my life The EMS system just came on and said tune to local media...instead of test.
House shook here n Lebanon, Indiana. We are about about 15 miles nnw of Indianapolis
Just heard about it on the AM radio news.
They’re sort of related fault zones.
Really there’s an area of heightened quake activity running all the way up to the St. Lawrence river valley in Canada.
There’s a very slim, but not negligible, possibility this is a foreshock to a much larger quake.
How much is earthquake insurance out there?
