What would you do if a tornado and an earthquake hit at the same time?

It may seem like a throw away question, but some friends of ours in Oklahoma are under a tornado watch (so are we) AND they’ve been getting hit by earth tremors all day. Ken, in Oklahoma, said he’s getting confused between rumbles of thunder and rumbles of earthquake (which I can tell you sound a lot alike…we felt and heard two of their quakes over the weekend) and he’s about ready to sell the house!
What if two big ones hit at the same time? Do you go in the basement…?? Or not??
Don’t you wish you lived in the Midwest!
