Yeah... there was an earthquake in ILLINOIS
Hey Bob - did you feel it - they said you should have been able to easily feel it within 62 miles

:wtf: Illinois? weird...
-
eh, not unheard of away from major fault lines..
hell look at this one in australia no less:

I didn't feel a thing...
but I'm used to small shakes as I live right on a fairly bussy road (as evedenced by my dog getting killed last week). I remember hearing a weird rumbleing sound at about that time, but I don't think that would have been it.
I do live right next to St.Louis, and this hit near Chicago, so that's probly why I didn't feel anything.
and Illinois is NOT away from major fault lines, the new madrid fault is a very powerful but less active fault it oftine goes many years without doing anything then BAM! 9.0, it's been over 100 years sence the last big quake, so were about due.
-
the last major new madrid (N.M. sits right at the bottom of the missisippi river along southern missiouri) was a 12er IIRC
-
4.5? You are fretting at a 4.5?
-
KT: they rarely happen here - and also we're in the Craton of this continent - seismic waves travel much more easily - an earthquake here can be felt around 10x further away than a same magnitude earthquake in california could be felt
So
California vs Midwest (Distance it can be felt)
1m vs 10m
10m vs 100m
50m vs 500m
[M being miles in this case]
-
Ah, point received.
Illonois is strange indeed.
-
*realizes that [V] is in Illinois*
-
yes - i've driven through Champaign-Urbana twice - no i haven't seen the [V] building
PS: they ammended the seimic reading - 4.1
-
So how did Interplay get the power to cause earthquakes?... :p
-
Ever phoned their technical support section? ;)
-
Yes actually... it wasn't pretty.
-
I've felt a few 4.0ish type Earthquakes growing up around here on the shores of Lake Ontario. There's a minor fault that runs through the middle of the lake and all around in here.
Its not a continental fault so its not as active or as destructive as ones along the edges.
I guess you have a similar occurance in Illinois. I also understand that somewhere down that way there is a fault line and that the last time it really did anything it was a massive quake that had the Missippi flowing the opposite direction for a few days...or so goes the legend. Anyone know about that?
-
IceFire: that big one is the New Madrid
-
yeah, New Madrid doesn't say much, but when it does it's on a thermonuclear scale.
-
Just like the Vancouver one....it doesn't do much, there are no serious building codes in place, but I remember readin that its well over due for the next serious movement...and when it does it could create a 9.0 or greater with possible tsunami damage.

if anyone cares...
I was looking for one of the sites that predicts things like the western half of the US will fall into the ocean becase of the madrid line, but I can't be assed
-
I slept through it. A 4 isn't much of a quake anyway. When it gets up to a 6, I might notice.
New Madrid is a fun fault to live near. Let's see, the last time it went off, it caused sand gysers, rang bells on the east coast and caused the Mississippi to flow upstream. I can't wait for doomsday.
-
Lots of your faults are due to go big - the San Andreas for example has a well documented periodic mass shifting which was due to happen awhile ago - it'll go sometime in the next twenty years, and the longer it waits, the more the pressure builds up.
-
Yay for me! :blah:
-
I think we had a minor earthquake here in northern New York a few years back. Can't really remember any details other than that I slept through it....
-
Earthquakes? Yikes... were there any casualties?
-
The one in Illinois? Of course not. 4.5 Magnitude.
http://en.wikipedia.org/wiki/Richter_scale
According to that article, a 4.5 Magnitude earthquake would cause:
"Noticeable shaking of indoor items, rattling noises. Significant damage unlikely."

You never felt a earthquake?
A 4.5 is barely a tickle...if you are doing something you may not even feel it. Sometimes the tree's will sway a bit in an odd motion or the paintings will get swung around a bit.
Once had a glass jar shake off a high ledge but it was already leaning over when the quake hit. We didn't even know there was a quake in that instance till later on the news. So a 4.5 is very slight...enough to feel it, but not the sort of building collapsing or casuality inducing kind.
-
...I've never felt an earthquake, either. But then again, Long Island was never known for having a fault line. Anywho, now that I'm on the continental part of NY, and possibly moving up to Saratoga, maybe I'll get lucky. :)
-
Just so you guys know, the quake was in northern Illiniois, think Chicago.
Bob and I live in the south, down near St. Louis.
-
Feel em in Vancouver on a nearly monthly basis. Most of the time it's this sudden jolt, barely noticeable.
If you're standing you likely wont notice it, sitting you may....
-
We had a quake earlier this year (http://www.kadmiel.com/kadmiel.com/articles/EARTHQUAKE--Israel_at_Risk.HTM). I was walking at the time and didn't feel it. :p
-
We had a minor 4.8 centred in Dudley in late 2002, I was up north so didn't feel it
-
Apparently, 2 (on average) 2.0 earthquakes occur in the world every day.
Oh, and IIRC the Richter scale isn't perfect - an earthquake will be felt differently depending on the depth which it occurs.
Strangely, the book I'm reading at the mo is currently sitting bookmarked at a page discussing the New Madrid earthquake. Apparently, these quake types (intra plate rupturings) are never known to happen at the same place twice.
