People live in lots of places that’s even stupider.
Like San Salvador, capital of El Salvador, built on the doorstep of the (active) Ilopango volcano.
Which is like having a neighbor with a pit bull. It might not bite you for a thousand years, but eventually you know it will, and when it does it’ll tear your face off. It’s just matter of time, because that’s what volcanoes (and pit bulls) do.
Ditto for Naples, with a Metropolitan population of over 3 million.
