Originally posted by Arbiter Well, most projections seem to suggest impact events of greater or equal magnitude to Tunguska every 300 or so years. That would seem to suggest we've got on average 200 more years before another event like that, and even an event approximating Tunguska is unlikely to cause overwhelming casualties unless it occurs in a location of extraordinarily dense population.

Yeah, but that can happen tomorrow or it can happen in 2000 years. Events like that are pretty stochastic.
