Has everyone forgotten already the worst winter on record for nearly 100 years!? Although it's not necessarily a natural disaster to get snow, we had more than our fair share this year and it did cause a lot of disruption. .
This has to do with being prepared. If you live in an area where a certain type of natural disaster is common, you (and the government, businesses, etc.) are prepared for it, in a business is a big deal.
For example, the northern US and Canada regularly get much more snow than the UK's "worse winter" and life doesn't come to a halt because government allocates more rescources to snow removal and people prepare their cars for snowy/icy weather.
DH lived in Japan and experienced an earthquake there, and he says that newer buildings there are designed with earthquakes in mind because earthquakes are expected. I suppose the same is true for buildings in San Francisco.
On the other hand, the River Ouse in York floods at least several times a year, but there are flood defenses and buildings are built to account for this - e.g. houses are raised and have no cellars. In fact, there is a pub in York on the river that claims that is the most flooded pub in York or something like that to attract tourists.
There have been times when I haven't been able to take my normal route to work because the path was flooded so I just went an alternate way, and it wasn't a big deal.
Lots of people in other places would be dealing with flooded basements and property damage during lesser floods just because their cities and homes aren't designed to cope with it.
(We did have an earthquake here a few years ago when I was here in the UK. I also think there have been some tornadoes in the UK, just not in York since I've been here.)
