Kinetic Damage from Meteorites

Abstract: A Near Earth object impacting into Earth’s atmosphere may produce damaging effects at the surface due to airblast, thermal pulse, or kinetic impact in the form of meteorites. At large sizes (>many tens of meters), the damage is amplified by the hypersonic impact of these large projectiles moving with cosmic velocity, leaving explosively produced craters. However, much more common is simple “kinetic” damage caused by the impact of smaller meteorites moving at terminal speeds. As of this date a…
