DID THE CATASTROPHIC EVENT CAUSE ANY OTHER CATASTROPHIC EVENT?
No. It just erupted that one time. It will erupt again. It doesn't take that long but it takes a while for another catastrophic event to happen like that.
HAS THE CATASTROPHIC EVENT CHANGED BIODIVERSITY IN THAT ENVIRONMENT?
Yes and no. Yes, because most of the things surrounding the volcano, once it erupted, mostly got burned. No, because everywhere else just got a big pile of smoke and lots of ashes.
