Earthquake in Indiana?

[ducttape45]

Here in Indiana, near Grissom ARB, we just felt what we think was an earthquake. Can anyone confirm?

[John W]

Yes, felt here in Wabash. 4.2 5 miles SE of Greentown.

The USGS website says yes.

[ducttape45]

I was just told it was confirmed by the USGS, exactly as you said.

When they get to 5.2 you need to worry since that's where they start breaking stuff. This might have knocked the bottom out of an old swimming pool or something, but otherwise it's nothing to worry about.

Carmel Fault most likely ~ runs parallel to that big one just to the West called "the Mississippi"!

Wow....I've been searching FR for 15 minutes looking for something like this post. I thought I was "feeling" things! It was an earthquake, all right!

I'm in a suburb 30 miles due west of Chicago.

I was freeping when the computer started shaking like a twenty-dollar television set.

Then my heavy computer chair started rockin' and rollin'.

The shaking created a dizzy feeling that hasn't quite left me yet.

I'm going to sit back and read further comments here. Thanks for posting!

This one reminded me of the small ones I would get when I was stationed on Guam.

I didn't know there was a "Carmel Fault" but a gentleman here says there is a fault that runs up the Wabash that is sort of connected to the New Madrid fault.

[ClearCase_guy]

The New Madrid Seismic Zone has the potential to produce very large earthquakes. There was quite a bit of activity there early in the 1800’s.

[ducttape45]

So you felt it up west of Chicago?

[ducttape45]

I’ve read about the 1811/1812 quakes that were, what, in the 8.0 range? I’ve been fascinated by the New Madrid since the time when I was almost stationed at the old Blytheville (is that how it’s spelled?) AFB.

"So you felt it up west of Chicago?"

Actually, it felt ME up west of Chicago, LOL.

Interesting, I know that the mantle across this portion of the US continent was pretty thin compared to other earthquake zones, but I didn’t think an earthquake of this strength would be felt up there.

Does this mean there is a six inch tsunami surging through Lake Michigan?

oh noes........

A TSA earthquake?

I heard a boomlike noise. Everything in my curio cabinets and hutch was jumping around.

I also saw my cat jump up in the air.

It was a good shake.
