When it comes down to it, there is no such thing as a natural "disaster". There are massive events that can fundamentally change human society locally and/or globally or even threaten life on Earth. Yet, really, they are only disasters because they change the status quo. Just think about how the Chicxulub asteroid impact at the end of the Cretaceous opened the door for the rise of mammals.
Of course, humans have a vested interest in not going extinct. We might have the tendency to do things that might hasten our extinction: see also, climate change, pandemics, nuclear weapons. Yet, when it comes to singular "disastrous" events, humans are pretty keen on thinking we can prevent them from happening.
