What in your opionion is the scariest natural disaster? I personally have always been fearful of tornados, they aren't common here, and the idea of something yanking you into the sky and hurling you to your doom freaks me out so much.
They used to be unheard of here. Literally the last one before 2013 was 50+ years ago and it's happened a few more times since. Earthquakes for me though. Seeing all that devastation in Mexico City was heart wrenching.
