An earthquake? In Wisconsin?

Well, it wasn't centered in Wisconsin, but supposedly you could feel it here. It's true. At 1:10 AM on Monday, an earthquake centered 70 miles southwest of Chicago (measuring 4.1) was felt as far north as central Wisconsin. I slept through it, but I've heard from others in Madison who said that it was actually strong enough to wake them up. As one UW-Madison professor was quoted as saying in the local paper: "First a tornado and now an earthquake? What is going on?" I agree-- I thought I was safe from these things by not living in California!!
