The damage from asteroid impacts is often measured in terms of areal extent and affected populations from the initial effects from blast waves, non-ionizing thermal radiation, and tsunamis (if the impact is over an ocean) [1-4]. We have considered the potential for additional effects, which could extend both to geographic areas affected and prolong risk to additional populations [5]. In...

Near-Earth Objects (NEOs) are a low probability-high consequence hazard with potentially catastrophic impacts. The Chelyabinsk impact in 2014 and recent technological advancements such as the Double Asteroid Redirect Test have brought planetary defense to the fore....
Since implementing the warning network systems for near-earth objects and bolide events, everything has changed for the safety of the planet [1, 2]. However, this has not been the case in the past, as
in the case in 1908 in Tunguska, Siberia, when an extraterrestrial object burned around 2150 km2 without any injury. Nowadays, the IAWN (International Asteroid Warning Network) is tasked with...
