I am, tonight, about 5 miles from the epicenter of these quakes and aftershocks. For the first one, the 5.2, I was home asleep, about 25 miles away from the epicenter. That was violent to me. Tonight I am at work, in a large powerplant on the In./ Il. border near Mt Carmel, Il. I am on the third floor in the control room. It was just a quick movement for us. We had spikes on vibration monitors on certain pieces of equipment when it hit and several of them came in alarm. We didn’t trip any equipment, though.
Being in a power plant is probably one of the safest places you could be in an earthquake. Those babies are built to withstand vibration.
