Thanks. Interesting how rare and extreme these events are. This suggests a runway process is involved in that the fire spreads and multiplies in just the right conditions, but presumably it takes a while for nature to grow enough to become vulnerable to a large fire again? Not enough data here to tell for sure. It is interesting that some plants have evolved to require fire to survive and reproduce (pyrophytic plants), so wild fire is by no means unnatural. There does not seem to be a positive trend here.
