Will natural disasters change the way we travel?

Over the last few weeks there has been a lot of media coverage about how people have been badly affected by the cloud from the Chilean volcano when they were travelling by air. Also, when a destination like Christchurch or parts of Japan are devestated by earthquakes, does this affect our desire to visit these places. I am travelling by plane in two weeks to visit my family in Christchurch. We have recently had floods here in NSW, and at the same time travellers were delayed by volcanic ash clouds and my hometown of Christchurch was experiencing more aftershocks. Once upon a time I just travelled, things worked out, sometimes flights were delayed or luggage lost. Minor inconveniences. But now I would like to know if others are delaying travel planes by air or are you just going ahead.
