There is always room for the once in 5,000 years flood. We got hit with a volcanic eruption in 1980. The previous eruptive period was over 500 years ago. Very few things in nature are "unprecedented." "Not in human memory" means little in geologic or climate time. Nature is very capable of events totally beyond any human agency.
