In a choice between earthquake risk and tornado risk, I think I’d have to take earthquake. (Knocking on wood and frantically crossing myself after typing this sentence.)
Check out this Scientific American video about tornadoes. Apparently, they have no idea why some storms make tornadoes and some don’t. And, meteorologists provide warnings a maximum of 13 minutes in advance. Get safe in those 13 minutes, or hope for a trip to Oz and a squished witch.
