THE ILLINOIS EARTHQUAKE OF 2008
"Shook Southern Illinois early Friday"
Friday 18 April 2008
A moderate earthquake occurred at 4:37:00 AM (CDT) on Friday, April 18, 2008 .
The magnitude 5.2 event occurred 8 km (5 miles) NNE (14 degrees) of Bellmont, IL .
The hypocentral depth is 12 km ( 7 miles).
The preliminary magnitude 5.2 earthquake occurred at 4:37 am Central Daylight
Time and the epicenter of the earthquake was about three miles below ground,
centered about 38 miles north-northwest of Evansville, IN., 128 miles east of
St. Louis, MO. or 6 miles northwest of Mount Carmel, IL.
It occurred in an area known seismically as the Wabash Valley Seismic Zone.
Today's event is the strongest earthquake in Southern Illinois since November 1968,
when a 5.4 earthquake occurred.
Classified as "moderate," today's event caused some damage and was followed by
aftershocks, the largest a M4.6 that occurred at 10:15 am Central Daylight Time.
Of much greater concern, however, is the potential for the adjacent New Madrid
seismic zone to generate severe earthquakes. During the winter of 1811-1812, a
series of three very large earthquakes — the strongest earthquakes to strike the
lower 48 states during historic times — devastated the area and were felt
throughout most of the nation. Occurring only a few weeks apart on Dec. 16,
Jan. 13, and Feb. 7, they generated hundreds of aftershocks, some severely
damaging by themselves, which continued for years.
According to the U.S. Geological Survey, there were few reports of damage
immediately after the predawn quake. In Louisville, Kentucky, three was rubble
in a street after a cornice fell off a brick building there.

Personal Accounts of the Earthquake
We were awaken to the sound of things shaking this morning, sat straight up
in bed and said what's that. My feet hit the floor at 4:41 a.m. and down the
hallway I went into the front room. The sound of things shaking in the china
cabinet and the picture window rattling add up to one thing "Earthquake".
Looked out the window and house lights were coming on all over the
neighborhood.
The news is saying it was a 5.4, up in Edwards County (West Salem area). The
one we had here in Southern Illinois the summer of 1967, felt bigger to me. but
it was centered a lot closer to us than this one.
There was a smaller one in the 1980's but I was underground in a coal mine
and didn't feel that one at all. Let's pray the New Madrid fault isn't going to
act up again.

We were awoken to a shaking house this morning too, here in Elizabethtown, KY.
At first I thought it was my 6 year old climbing into bed with me and I looked
around realized it wasn't and just thought then it was something happening at
Ft. Knox since we live so close to it. My daughter came in my room around 6 and
said we had an earthquake..... I was like, no way. We personally have not exper-
ience any damage but down town Louisville has some minor damage to some buildings.

I was woke up a bit ago to a load rumbling and then all of the sudden the whole
house started shaking. I grab the kids and ran to the basement with them as fast
as I could thinking there was a massive tornado over top of us. The windows were
shaking and rattling so bad I though the were going to break. One it was over I
went outside to have a look and it was as calm as could be. So this got me to
thinking,how could it have been a tornado??? I have lived through one tornado in
Florida, so to me it was the same sound and shaking going on. My next thought was
an earthquake, but what was the loud rumbling sound.
I am in DuQuoin Illinois and my other halfs G-ma is in Murphysboro and she
called to say she was awoken by it.
We all know around here is the New Madrid fault, but never thought much of it
till now.

I felt the quake all the way in Godfrey Ill where i live my husband & I both
felt he thought we were having a storm, and much to our surprise it was an earth-
quake very creepy to here things rattling in our never been thru anything ever
like this.
Susie INGRAM
We felt it all the way up here in northern Illinois. It started with a low
shaking, the a feeling like the house was "rolling", then harder shaking and then
it lessened and stopped. It lasted for at least a minute.
Kim
I live in Grayson County Kentucky (about 70 miles south of Louisville) and it
woke me & my husband up at 4:39 AM - the windows in my house rattled!!!
Cathy SCHULTZ
No way I would be up this early for too many reasons..but we had a
quake! Had to be. I was feeling the bed shaking..thought Brutus had
come into the room and was leaning against the bed while scratching
or something (big dog people can relate...) and it got worse, and
worse, and we both popped up out of the bed and got out of the
room!! It's 4:43 a.m. now so this was at ~4:38 a.m. and lasted about
40 seconds. Everything was rattling!! Not a train/truck or anything
on the road...no noise except the rattling of the lamp and of course
my BP sending a swishing sound through my arteries!!
Trish, Philo Ill.
It woke us up about 4:36 this morning here in Grayville (which is rather
close to the epicenter in West Salem, IL); lasted for about 40 seconds. It
knocked some pictures off of some walls; shook the doors of the medicine
cabinet open & the contents spilled into the sink; our town's water pumping
station apparently had some damage but is repaired now and we lost power for
a while. However, WE don't appear to have any house damage; haven't been
uptown to see what other people are reporting. I hope that the New Madrid
Fault goes back to sleep.
follow up:
So far here in Grayville, a building housing a beauty shop uptown lost a couple
of bricks. I was told at the bank yesterday that the Super 8 Motel here had some
damage but that was an unconfirmed report.
Carol GARBO, Grayville, IL
I live in Florissant Mo. I didn't feel the quake this morning but my birds were
going crazy and my son said his bed was shaking . About 10:15am we had a after
shock. Right before the aftershock, I heard a boom, my birds went crazy, the
water in the fish tanks started to sway and everything started to shake. It sure
is unsettling.
Sandy GENTRY
I was on the phone with my best friend and distant cousin who lives in Havana, IL
- north of Beardstown and south of Peoria when the aftershock hit. All her plants
were shaking and one even moved off the table it was sitting on. It lasted about
45 seconds. She woke up with shaking this early this morning. Her dog didn't seem
to notice anything but with this after shock the dog howled and she said the birds
disappeared.
Sara HEMP
We felt it here in Eastern Indiana and in Dayton, Ohio it is all over the news.
People felt it there too. That’s over 300 miles from the epicenter!
Michelle Kennedy Byrd, Eastern Indiana
I've been through several minor earthquakes in Southern Illinois and Southeast MO.
We are on the New Madrid fault. Yes, I felt the one this morning. It woke me and
I said to my husband, "What was that?" Then I realized it was an earthquake. I
looked at the clock and it was 4:38 a.m. on our clock. It shook our bed and the
windows rattled. Hope that's all for a long while.
Anna NEWELL
I was up reading email this morning at 5.40s when the quake it, to me it felt
like a large gust of wind hit the house and sounded a little like bomb wind.
with no explosion sound, just a pressure of it. The desk and computer monitors
rattled a lot. No noticable damage to the house. In the car when the second one
hit so we didn't feel it. didn't learn of the 2nd one until i read my mail again
this afternoon.
Lonnie, Bedford Indiana
Gail and I live in Mulkeytown - about 12 miles from Benton west. I first
thought it was hail hitting the house when it woke me up and Gail said
he thought somone was banging on the laundryroom door. Then he went in
the living room and saw the blinds shaking. We do no remember that the
dog acted very cowed the evening before. They say animals can feel when
something is going to happen.
Our daughter's family live in Ewing and my son-in-law said their house &
floor vibrated and the noise was like when the washing machine gets out of
balance.
I was cutting material when the next shock came and I thought someone had
come in the door at my shop. Felt strange when there was no one around either
door. Then I got a call from Gail at General Cable in Du Quoin that they
felt that one and a fellows tool box almost turned over.
Sorry to be so long winded. But this is from the other side of the county.
Barb Spencer, Mulkeytown, Illinois
I was at a table in the high school at 10:15 a.m. this morning and the shaking
started again. (after shock). The young adults weren't the same the rest of the
day. I'm glad we had a short day at school today. ;-)

The earthquakes still continue today, although the are holding around the 4.+
category. Makes you wonder if something bigger is still yet to come.
