There are a few questions here about whether tourism monies ameliorate the effects of a disaster, and this lends some credence to a theory that a disaster can drive additional traffic to a region that had a history of tourism. Possible examples: Perugia, Italy post-earthquake, Indonesia post-tsunami.
This question asks if there are any known regions where a near-term disaster opened up new tourism inflows? This is mostly driven by the current wildfires in Chile. It led me to ask if certain undiscovered primitive sites were exposed through a disaster like fire? Something like hidden Mayan or Aztec ruins via a jungle wildfire? Or possibly, hidden lake-engulfed cities exposed by drought?
