When I was buying a house my first priority was not vulnerable to fire flood or tsunami.  Most of Australia is vulnerable to fire or flood and I have felt very lucky to be sitting pretty through it all but now, with another year of flooding ahead we are worrying about mud slides - I have a little pool of ground water in the cupboard under the stairs, the water table has risen a lot but not that much, I'm on a hill, it's the water running underground.  

I am still more scared of drought, though probably even more scared of what people can do.
