As you probably already know these quakes are coming from the Wabash Valley Zone but unfortunately the two faults are in line with each other.
This is a informative website about these 2 faults.

where is your general location?
Yet another quake, a 4.5, hits the region

Saint Charles, but I’ve been flying back to MA on the weekends.
That’s Saint Charles MO
LOL... yeah there is a St. Charles IL. :-)
but I lived in St. Charles MO in the early 90’s
I am currently along the MO/IL border in Southwest IL just across from Perryville MO.
Anything in that general region makes me think of the New Madrid fault. I don’t like that prospect one bit.
Another quake rumbled early this morning

Yeah, there’s a lot of places that are known earthquake areas (like Manhattan Island) that are not anywhere built to the standards of construction that would withstand a likely earthquake. Especially in the New Madrid Zone where buildings built after the last Madrid quake are made out of unreinforced brick.
If or rather when there’s another significant quake there, it won’t be a rude surprise, it’ll be a nightmare for the thousands who will find themselves in brick rubble.
Have you lived there long SLN.I bet you and I know some of the same people. Heck I might even know you.
My sister and I both live in the Chicago suburbs. She was awakened by the quake. Said it shook her bed, and she knew immediately that it was probably a quake. I, on the other hand, slept right through it (I’m one town over from where she lives). Well, at least if a bigger one hits, and assuming I don’t get creamed by it, I’ll probably stay asleep and thus will remain calm as I will be asleep. Unless of course the quake hits during the day. Then I’ll rock and roll with the rest of the folks.
We have talked before about the area.
I am a transplant here and it is possible that we both know some of the same folks. But you know how it is here if you are a transplant to the area.
Oh yeah, I am sure you have been talked about, suspected as an undercover cop and lord knows what else.It’s a nice rural little town, however, lots of drugs move and made in that county. I could probably name key players.My mother and sister still live there but am glad I got out almost 40 years ago.
Speaking of drugs... they just made a crack house bust right near the Randolph County Court House last week.
But really the drug problem is not that huge around here as it could be.
It is much bigger than you might think. Yes it is under the wire, more dealers than users. The pot is grown amongst much of the farmers crops where it goes mostly undetected. Lots of old farm houses and barnes where it is processed after harvesting. Don’t get me started about the meth labs in the surrounding areas, made there and sold up north around St.L or down around Murphy and carbondale and Marion.
A large New Madrid quake is likely to be a whole different animal from the coastal quakes we’ve heard about. It’s possible that the quakes in December, 1811, January, 1812, and two February quakes (four large ones, as felt by people) were actually effects of one long disturbance. Effects felt as aftershocks really overlapped from the first perceived large quake until long after the last. Although the worst of the perceived and reported shocks is estimated to have been only 7.5 or so, there are other considerations (land elevations greatly and permanently changed, “sand blows,” strata different from coastal regions, etc.).
Interesting comment about the water lines. Supposedly the one the other day was felt here in Tennessee (I didn’t feel it). Last night at work, we had no water ... as well as the rest of the town for about 12 hours. Found out this morning that a main water line broke. Wondering now if there’s a connection?
Have plenty of batteries, flashlights, candles and lanterns available. Power will most likely be out, probably for days. Our power was out for several days after the 1989 quake. It also helps to have a battery powered TV set, helped my family to find out what was going on. Upon evacuating from my jobsite in 1989, me and some co-workers came upon a guy with a portable TV in a parking lot. A lot of people were walking towards the Bay Bridge, but we learned from the TV that it was out.
So figure that lots of bridges may be closed. Probably would help to have maps on hand (and a portable GPS device). Also know where your family members will meet up. Communications will probably be down. I was lucky, as I was on the telephone with my wife as the quake hit, so I knew my family was alright. Also figure that it will take a long time to drive anywhere, as traffic lights will be out, and debris will be in the streets. I saw lots of glass and bricks from chimneys in the streets. Not to mention people walking in the street (afraid to be on the sidewalks).
Have cash on hand, as credit cards will be useless. Have an ice chest ready to go, stocked with survival items. You may have to leave your home if it's damaged. Hope this helps when the New Madrid fault lets go with the big one.
I am hearing reports of many water line breaks (small & large water lines). I think there was a main break in St. Louis also. (some 128 miles away from the center of the 5.2 quake)
Marion IL is about midway point (about 64 miles) from the center of the quake.
Over the years all we hear about is the New Madrid fault in this area. But I am really starting to think the Wabash Valley fault is the one that we need to worry about as it has produced many 3.0 and over quakes since I moved to the area in 1994. (I have felt just about everyone of the 3.0 and over quakes from it and I am at least 125 miles away from it)
I am actually on the New Madrid fault and I never feel it moving even though it does move much more often than the Wabash.
I know after the 2002 Wabash small quake, my quake insurance went up quite a bit. I know now it is going to jump up probably much much more now.
Well I am tired, time to crash!
I am, tonight, about 5 miles from the epicenter of these quakes and aftershocks. For the first one, the 5.2, I was home asleep, about 25 miles away from the epicenter. That was violent to me. Tonight I am at work, in a large powerplant on the In./ Il. border near Mt Carmel, Il. I am on the third floor in the control room. It was just a quick movement for us. We had spikes on vibration monitors on certain pieces of equipment when it hit and several of them came in alarm. We didn’t trip any equipment, though.
