This is what happens when you vote for Huc... *cough* I mean, I hope everyone’s alright, that is a strong size when you’re not in earthquake country.
People keep saying they’ve felt these, but I never notice. (500+ miles away)
I just hope this isn’t a prelude to something really damaging.
Mr G felt the table shaking, and I heard a very low rumble when it happened. I immediately started looking on the internet to confirm it, and knew it would be here.
Not nearly as intense as the one Friday. That one woke us up from a dead sleep, and the bed shook pretty well for a while. This one we would have slept through.
Unusual.
Earthquake Ping.
Anything in that general region makes me think of the New Madrid fault. I don’t like that prospect one bit.
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.).
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, 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.
5.0 and up is reportable. Below is not worthy of a thread.
This quake was downgraded to a 4.0.
I knew it felt weaker than a 4.5, because of the 4.6 I felt the other day.
We just had another 4.2 quake on the same fault (Wabash Valley)
