While in Indianapolis "YMMV"...*I* did not feel anything, and was awake (though, laying in bed after my alarm going off at 5:40).
However, HW might be a little more concerning (especially if you've seen the Evansville news station YouTube vids), BUT...since it didn't last long, I'm guessing HW will be ok, but inspections will be needed....
Although there are reports (and photos on CNN and Yahoo) of brick building facades damaged in Louisville I suspect we won't see any reports of major damage. While no doubt the folks at HW got quite a wake-up call this morning I'm sure all is fine at the park, although I bet there is some cleaning up to do at the grocery store in town.
Sorry...I find it very hard to believe anyone in Florida felt this quake. Pensacola, the closest major city in Florida to the epicenter (Salem, Ill) is 700 miles away. I'm only 350 miles away from the epicenter of the San Francisco shaker of 1989, which was almost 1,000x stronger, and I didn't feel a thing, and I was watching it happen live on the World Series.
EDIT - Paula posted about it on the HoliBlog, right as she was experiencing the 4.5 aftershock.
While similar-strength eastern earthquakes tend to be felt further away than those in California (i assume because the ground is overall more rigid due to fewer earthquakes, and that they're not as expected) I also doubt it could be felt in Florida by a human.
Great sense of humor shown by Paula, though, making it a point to quickly tell everyone the coasters are okay!
Two Magnum trains bumped into each other during the quake and it will now only run during the hours of noon to 4 pm, every third thursday of the month, given that the weather is clear, sunny, and between 68 and 74 degrees.
