Earthquake

4:42 a.m. Just a few minutes ago. Springfield, Illinois. I've been in several in thsi town. This was the longest. This was the most violent. Also, I woke up before it happened. I don't know. I think there may have been more, which made me wake up. Checking.

jpmatth Twittered it at the same time I did.

Looks like this was in the 5+ range.

This was really violent. What I was trying to say above, when I was less coherent than I am now, I think there was an initial shock, which woke me up, then the longer more violent one, for which I was awake the entire time. That's probably not as coherent sounding as I intended it to be.

5:11 a.m. Rebooted, went outside, came back. Okay. This was a 5.4 magnitude at 3.1 miles deep.

* 12 km (7 miles) E (90) from West Salem, IL
* 13 km (8 miles) NE (53) from Bone Gap, IL
* 14 km (9 miles) W (266) from Allendale, IL
* 36 km (22 miles) WSW (241) from Vincennes, IN
* 67 km (41 miles) NNW (335) from Evansville, IN
* 206 km (128 miles) E (93) from St. Louis, MO

5:14 a.m. This is kinda weird, but I can still feel it in my chest.

5:18 a.m. Confirming this was the Wabash fault, not the more famous New Madrid one we know so much more about.

5:23 a.m. Okay, listening to radio. Not confirming Wabash, yet. I have to say, until a few years ago, I never even heard of the Wabash fault.

illinois_basin_ozark_dome_sz.gif 5:36 a.m. Just heard on radio: Sustained shaking for a minute. Damage in Louisville, Kentucky.

USGS "EARTHQUAKES IN THE ILLINOIS BASIN - OZARK DOME REGION">USGS: EARTHQUAKES IN THE ILLINOIS BASIN - OZARK DOME REGION: "This large region borders the much more seismically active New Madrid seismic zone on the seismic zone's north and west. The Illinois basin - Ozark dome region covers parts of Indiana, Kentucky, Illinois, Missouri, and Arkansas and stretches from Indianapolis and St. Louis to Memphis....

"Earthquakes in the central and eastern U.S., although less frequent than in the western U.S., are typically felt over a much broader region."

5:51 a.m.: Radio. "A 5.4 earlier this year in Baja, Mexico, left 400,000 people without power."

5:53 a.m.: The radio I'm listening to, of course, is Jim Leach at WMAY. And, Springfield journalist and blogger, Rich Miller, who has been in contact with Jim, felt it too: Morning video - Earthquake edition.

6:00 a.m. It made the national radio news. Interviewed Cindy somewhere, who was sleeping in the turret, was woke right up out of bed.

6:04 a.m.: More early morning reportage:

6:10 a.m. Guy on radio: 911 center was overwhelmed for ten minutes straight.

6:18 a.m. Radio: This was not the big one, which is inevitable, and which we've been bracing for. But, it may have released enough pressure to stave off the big one for a while. (Paraphrasing.)

Getting ready for work.

11:23 p.m. There were several aftershocks, one of which was a 4.6 at 10:15 a.m.

Excellent coverage from the SJ-R:

To top the day off, when I got home from work tonight, the electricity was out. A truck hit a utility pole on 11th Street.

Yup I have a very wake and jolted GF in Decatur IL saying she felt it and watch our tv stand jump about and I run a store there and it felt it, nothing to bad saw one blogger say that he felt a 5.4 (in south east MO) but nothing yet on any news of it.

Yup, that was an Earth Quake alright.

Now to get back to sleep.

I'm in Springfield, Illinois - Downtown area - it's 5:17 right now, and dear Lord, that one woke me straight up out of my sleep! I remember the earthquake we had, the dinky little one a couple years back that kinda shook a few lamps in the middle of the night. And then there was the factory blowing up that made some houses move a bit, but this was truly violent! MAN! I went FLYING down my stairs, asking my mother (whom I'm visiting with right now before I take off back home to Ontario) if she was alright)

This unstable 1800's house just doesn't seem right, lol. So, being this far away from the fault, it still caused some damage, we have a piece of siding that is hanging off of our house outside. Weird. And a lamp fell over! Phew, close call guys ;)

INTERESTING though, very interesting. I'm ready to get back to Canada-land after this one!

I'm in Columbus, Ohio and it woke me up. I couldn't figure out what was making the bed shake and had trouble sorting out what sounded like sniffing sounds.

As absurd as it was (and I was sleeping, you'll recall) it seemed as if a happy dog, tail wagging rapidly, had jumped up on my bed and was sniffing around.

I've heard of the Wabash fault before. This same fault rocked us around back in the 1980s.

I also have recollection of several of these when I was a kid too.

Time to go back to sleep.

I didn't mean for that to sound as light as it was. I've had about 4.5 hours of sleep and am not thinking as clearly as I could be.

I hope everything is OK in Springfield.

WOW, Marie. Hope everything is alright. I never think of earthquakes in the midwest.

Great stuff, Marie (and everyone else).

I'm sure you've heard by now that today is the anniversary of the 1906 San Francisco Earthquake, which caused quite a commotion (and leveled the city) back in the day. One April 18, as we were preparing to go to press with the day's first edition of the Examiner (which of course had a story on the quake anniversary), we had three pretty sharp quakes in about 20 minutes. Very, very unsettling -- and quite a coincidence. ...

When I turned Twitter on yesterday I was inundated with tweets about it (I track the word earthquake, being from California and all..)

Having an earthquake in the midwest must be the same kind of disconnect that would happen if a tornado touched down in the middle of California (and I'm talking about a real tornado, not those little offshore things that happen here sometimes).

Part of me wanted to jump in and be reassuring but the truth is that there's just nothing reassuring about an earthquake. They suck, plain and simple.

I'm glad you're okay!
