Fun with the Apocalypse

Those of us who live in earthquake country have this handy-dandy resource to turn to when the ground shakes: we can see if that quiver that went through your house was local and small or large and far away.  It's part parlor game and part reminder to keep bottled water and pull-top tuna cans on hand just in case you have to survive until help can helicopter in from Texas.  (You are keeping water, right?).

I'd still rather have earthquakes than tornadoes or hurricanes.  Or for that matter, winter.  Give me 20 seconds of terror over three months of shoveling white stuff anytime.
