You are asking for help to answer a question that only you can answer.
We don't live in "your area", you do.
We don't even know where that is!
Have a good think about the question, do a bit of research (Google, etc) to identify what sort of disaster/s is most likely to occur where you live .... then create a survival plan for the people who live there.
How could they plan ahead, before the potential disaster actually happens?
And what should they do at the time & after, to maximize survival rates?
Come on, you can do that!
