Asteroid impact effects and their immediate hazards for human populations
@article{Rumpf2017AsteroidIE, title={Asteroid impact effects and their immediate hazards for human populations}, author={Clemens M. Rumpf and Hugh G. Lewis and Peter M. Atkinson}, journal={Geophysical Research Letters}, year={2017}, volume={44}, pages={3433 - 3440} }
A set of 50,000 artificial Earth impacting asteroids was used to obtain, for the first time, information about the dominance of individual impact effects such as wind blast, overpressure shock, thermal radiation, cratering, seismic shaking, ejecta deposition, and tsunami for the loss of human life during an impact event for impactor sizes between 15 and 400 m and how the dominance of impact effects changes over size. Information about the dominance of each impact effect can enable disaster…
