So there was a 5.2 earthquake in Southern Illinois. That's a big deal.
This article mentioned that the skyscrapers in Chicago were rattling. Really? Almost 250 miles away??? I guess our buildings here are built differently than in Chicago so I'm sure it's possible. And a 5.2 isn't exactly small potatoes.
I'm addicted to this page, which is also on my links list. Southern California faults have been eerily quiet lately so maybe something's going on down under.
