How would you prep for big disaster?

I'm not sure if this is okay to post, please delete if not appropriate.

We all know there's been talk about "something" happening/going to happen, such as a big disaster. I don't want to get into if there's a disaster, what would cause it and what would be etc.. I just want to know if you believe there is a disaster coming, how would you prep? I don't mean infinitive money doomsday bunker, more everyday people.
