Incase you're too lazy to open every tab and download it, like me. :P

NONE OF THESE ADDONS ARE OWNED BY ME, NOR ARE THE IMAGES, VIDEOS ETC.

Addon explaination from creator, Business Cat:
This is the single largest disaster addon to exist on this game. Everything from tornadoes to tsunamis to earthquakes exists here. While for the time being, not everything is in here, you can play with: EF0 to EF5 tornadoes, fire tornadoes, earthquakes, tsunamis, and even tar pits.
