Okay, I just happen to live in OK, in that part of the U.S. known as 'Tornado Alley'. I've been here all my life, so twisters don't really freak me out. The drill is to get low and in the central part of the building. No biggie.
But do you do when you've got both a twister and an earthquake at the same time??
For those that might be bored, pull up your favorite weather radar and look at OK. In another tab, go hit up the real time seismology link at the USGS. Compare locales.
Wonder what happens if a F3 or bigger hits at the same time and place as a M4 or higher...
