In case you missed yesterday's "Day in History", it arrived a little late in the afternoon, but all of these are being archived for future reference.

Mornin'

Good morning! Yeah! It's Friday! And pay week....Woo hoo! All is right with the world, at least for today.

Have a great weekend. 32 here.

Good morning! Nice slide show featuring Dan Urbanski today. All of those pictures are great.
First thing I did when I got home from work yesterday was check out the slide show. Thanks for getting it to work.

Have a nice day!

Good Morning Yoopers! I live in Indiana and this morning we had a 5.4 magnitude earthquake at 5:38. No damage here, but it sure caught us by surprise. Our windows rattled and the floors shook. We live on the New Madrid fault line and in the Wabash siesmic zone. I would love to get Capt. Paul's input on this. This doesn't happen in Indiana very often.

Good morning from Mishawaka, IN.
Cindy, I live in the northern part of IN (almost in MI) and felt the earthquake this morning. I knew what it was after I saw the lamp shade swaying. It was a little scary to say the least.
Have a great weekend everyone.

Felt the earthquake in southeastern Indiana (northwest of Cincinnati).

Good Morning, Everyone! Yay, it's Friday! It's been a really long week, here. But, we did have some welcome sunshine & blue skies, even if it's cloudy today, and rain is in the forecast for the weekend. :-)

From the first I heard of the earthquake down in southern Illinois, I wondered if it was on the New Madrid fault, and what Capt Paul's thoughts on it were? Is that the main quake, or is it the precursor to a bigger one? Thanks, Capt, in advance. :-) (And, no, we did not feel it here in mid-Michigan.)

Matt and Charlotte- We live in east central Indiana on the Ohio-Indiana border, about 80 miles east of Indy.

Culled the following from CNN:
A magnitude-5.2 earthquake, centered 131 miles east of St. Louis, Missouri, struck at 4:36 a.m. (5:36 a.m. ET) The epicenter of the earthquake was about three miles below ground, six miles northwest of Mount Carmel, Illinois, and 38 miles north-northwest of Evansville, Indiana, according to the USGS.

They also said that it was felt as far away as southern Michigan, but I'm afraid I was still in bed in Lansing at that time and didn't notice anything. Anyone else feel it?

Hoosiergirl: I didn't feel the earthquake, but the news this morning reported that it was felt at our two bigger hospitals and some other building that I didn't catch. And we're way north in Flint, MI!

I love hearing reports on how far away it was felt. I heard this morning on the news from Indy, that a relative from the Quad Cities area also felt it.

Charlie, could you give us a link to the first image you used in today's This Day in History? My jaw just dropped when I saw that; it's stunning! Thanks!

Dave ~ You can find the photo your talking about in the Archives, on Aug. 19, 2004. It was part of our week-long tribute to Dan Urbanski. He sure had a great talent!

Also felt the earthquake here in Milwaukee this morning. My bed was jiggling a little and I thought that one of the cats was dancing around.

In central Indiana this morning, there was, indeed, "A Whole lot of Shakin' Goin" on. The last quake (magnitude of 5) that I recall feeling here was in 1987. Its center was located near Olney, IL, a few miles north of the center of the earthquake which occured this morning.

koskintoronto, visited with your Dad last evening. Brought some show 'n tell along and we practiced the internet on the computer.

Felt the quake in Bethel, OH, we're about 30 miles east of Cincinnati. We were still in bed and I felt the bed shake....I thought my husband was having a "chill". He thought it was wind, felt it and heard it. Had one in 1987 and also one in our area in the summer of 1980. Experienced several of them when we lived in Bakersfield, CA. A very spooky feeling one never gets used to, no matter where you live.:(

Actually, this was the first I have heard of the earthquake (I was sleeping in this morning!! ;-)

While large earthquakes don’t happen in that region often, many smaller ones occur quite frequently. With the quake this morning, I imagine most people felt the magnitude 5.2 quake that occurred at 4:37 am this morning, but no one felt the magnitude 2.5 aftershock that happened at 5:03 am. Usually, the only way to detect the smaller quakes is by seismograph equipment. The same holds true for New Madrid, where hundreds of smaller quakes occur each year, they just are not felt by people. Just as a side note, the quake this morning was felt as far away as the Upper Peninsula.

Speaking of New Madrid, the quake this morning does not appear to be related to that structure. This quake appears to be part of the Illinois Basin - Ozark Dome Structure, which borders the New Madrid Zone, but is not part of it. Most bedrock in this region were formed as several generations of mountains rose and were eroded down again over the last billion or so years. Anytime you have multiple mountain building events, you will have multiple faults in an area (case in point, the Appalachians).

I have provided a couple links below that have good information about the quake and where you can report if you felt anything (YES, you can be a part of science....)

USGS Illinois Earthquake Information

Did you feel it?? Report it here

I have some work to do today, but I will check back later with more info and some associated hazards with these mid-continent earthquakes....

Good Morning. Is that the fault that caused that 8.0 quake near St Louis in the Early 1800's? The building codes in that area require some Earthquake structure because of that fault and the high risk of another large quake.

By the way have seen lots of birds lately!

This earthquake news is interesting. Not all that long ago, a couple months ago, on a HistoryChannel program the early 1800s earth quake was featured and on this same show mentioned another quake would happen again in time from St Louis and eastward.

Brooke, we too have seen a lot of birds. Here are a few dozen of several hundred that arrived yesterday.

Here North of Knoxville,TN. Union CO. it seems like Spring has been here for quite some time now,with a lot of warm days with no humidity, enough rain, and some days that are just to cold for us Southern folks. Haven't heard the Whipperwill as of yet, or seen a Humming bird. Lots of pollen on the car windows to hose off. Did not feel the Quake around here that I know of. Good afternoon all.

I was surprised to see my car covered with a heavy coat of pollen this morning!

About the earthquake.....seems there was a hefty aftershock just a little over an hour ago. I didn't feel that one....was mowing grass with my lawn tractor.

Where is Scott AFB relative to the epicenter?

Marsha in Genesee: You often mention the weather or happenings in your area. Where do you live? In Flint or north of there. I am in Holly on Holly rd. Many of the doctors we go to are on Linden and Corunna Rd. area.

I got shaken out of my sleep in Nashville, TN this morning by the earthquake. In my sleep induced daze, I assumed it was my dog scratching his ears and pounding his back paw against the floor. I was tempted to wake my wife to tell her that she needs to bring the dog into the vet because his scratching is worse than ever. In the morning, I found out that it was not my dog, but an earthquake. It seemed to go on for about 20 seconds.

Carole: I'm in the town of Genesee which is at the NE corner of Flint. It's where Mott Lake and Huckleberry Junction are, and we are in the vicinity of Crossroads Village and the Genesee County Fairgrounds. I am about a half hour from where your doctors are located. In fact, I was out that way to The Olive Garden and Sam's last night. I live on Genesee Rd. in Genesee Twp. in Genesee County in the town of Genesee!

Thanks, Rowdy. I'm sure he appreciated the tutorial.

Marsha, being fairly new to this area (came from Sterling Heights two years ago) I was not aware there was a town called Genesse. Was to Huckleberry Railroad years ago when the daughter was a young teen. (she is now 36).

Where is Scott AFB relative to the epicenter?

If the earthquake was centered near West Salem, IL, as the news account I read indicated, Scott AFB is about 130 - 140 miles due west......near Belleville, IL, just east of St. Louis, MO.

Hei Dave, I think it's 'whip-poor-will'. Snow is mostly gone here in Cornell. Lots of water in the lawns and the drainage ditches are 'bout half full. Sounds nice as it runs over branches and/or stones. Spring music. Peepers will be singing soon.

Earthquakes in that area of the US are very interesting becuase the characteristics of the bedrock transmit earthquake waves much farther that they would in the western US. If a magnitude 5.2 quake occurred in California, it would not have been felt as far away as this quake because of the underlying rock types.

And now for some of the hazards. One hazard is landslides. In the Mississippi River Valley, there is a lot of loess which is rock flour created by glaciers. When shaken (not stirred), loess becomes very unstable. The second hazard, which is much cooler, is liquifaction. Liquifaction occurrs where there is water satuated sediment. When shaken, the sediment turns to liquid. Houses built on this type of sediment can actually sink into the ground like a ship sinking into the ocean. Also with liquifaction, you can get what are called sand volcanoes. This is where the shaking creates water pressure where the sand erupt out of the ground and flows much like a mini lava flow.

Any other questions, just ask ;-)

Well, Whip-poor me-if you-will Ken. That makes a hole lotta sense to me Capt.Paul. My question for you would be, if I sent you a picture of my foot, could you tell me if it is athletes foot? ;<) If you haven't been over on to the Global Warming page to read Dr. Nat, do so now while you have the time. Enjoy your weekend,just like Mother Earth,it's mine too.
