Archive for April, 2008

It was a little after four thirty in the morning. I was at work, cleaning the kitchen in the apartment where my clients live, having just finished making lasagna for their weekend meals.

All of the sudden, I was having a hard time keeping my balance. Now granted, I do have a balance problem which is connected to my deafness, but this was more than that. And since I reserve any drinking I do for my days off (besides, I’m not that big of a drinker anyway), I knew I couldn’t blame my unsteadiness on alcohol.

Nope, there was something else going on here. The building actually felt like it was…

shaking.

This wasn’t the normal shaking that one might feel when a semi passes by your home. Besides, the apartment was in a large complex away from any major traffic, so there wouldn’t be any large trucks outside the door. This was something that actually made the furniture shift a couple of inches.

I immediately went outside, only to find that the neighbors were also outside standing around in the parking lot, with the same puzzled expressions as myself. Obviously I wasn’t the only one who had felt the trembling.

Since the apartment was located close to the airport, the first thing that went through my mind was a possible plane crash. But I didn’t see anything that looked like a fire, and the neighbors didn’t hear any sirens.

So I went back inside, only to discover that my clients (both of whom are developmentally disabled and mentally retarded) had woken up, and were freaking out in the living room. They couldn’t understand why someone would come in and shake their beds. After calming them down and escorting them back to their rooms, where they looked upon their mattresses with nervous suspicion before finally climbing back under the sheets, I grabbed my trusty SideKick and put in an emergency text message to the office.

The building here just shook big time, and it freaked out the clients. Anyone know what’s going on?”

The answer came back a few minutes later…

earthquake.

Yup, folks… southern Indiana got visited with an earthquake this morning.

According to the U.S. Geological Survey, the quake registered 5.2 on the Richter scale… not all that impressive when compared to Los Angeles earthquake of 1994, which measured 6.7… or the Alaskan earthquake of 1964, which measured 8.4 on the scale. Nevertheless, it was still strong enough to put cracks up a schoolhouse in West Salem, Illinois, which was close to the epicenter of the earthquake… less than sixty miles away from Evansville. It also did some damage as far away as Louisville, Kentucky – a good two to three hours to the east.

And of course, to rattle a couple of people’s nerves.

An earthquake in the Midwest??? Actually, it shouldn’t be all that surprising. The area around the Mississippi River between Saint Louis and Memphis is home to the New Madrid Seismic Zone, the most seismically active area in the country east of the Rocky Mountains. Some scientists predict that the next “big quake” won’t happen in California or Alaska – both known for their earthquake activity. It will happen right in the nation’s heartland. Indeed, major earthquakes estimated to have registered around 8.0 or higher did occur here back in 1811 and 1812, which changed the course of the Mississippi River and entirely destroyed a town which is now underwater. It is estimated that a serious earthquake in the New Madrid Fault Zone could actually devastate 65% of the city of Memphis in Tennessee and do significant damage elsewhere as well.

We ended up having an aftershock later in the morning around 10:15 which registered 4.6 on the scale. The morning’s earthquake is said to have been felt as far away as Chicago, Kansas City, and Memphis.

It’s not the first time I have felt an earthquake, but it hasn’t been a common occurrence in my life. I can’t say that it’s something I would care to repeat.

But at least we can be thankful that there was minimal damage and no report of injuries.

Next time we might not be so lucky.

This is a damage range comparison between an earthquake in the New Madrid Seismic Zone area and a comparable earthquake in the Los Angeles area. As you can see, an earthquake in the Midwest could have some long-range devastating effects over a greater distance than one in California
