Description
Initial effects of asteroid impact and airbursts include thermal radiation and overpressure blast waves. If sufficiently large asteroid fragments reach the surface, seismic activity or tsunamis may occur if over land or sea, respectively. However, other effects that could extend the geographic areas affected and/or result in long-term physical hazards are less characterized. We categorize these as either downwind or downstream effects. We address the question of when do these effects become non-negligible for the loss of life, ecological damage, and disruption of economic activity.
