Scientific paper

Disruption or mitigation of a potentially hazardous object (PHO) by a high-energy subsurface burst is considered. This is just one possible method of impact-hazard mitigation. We present xRAGE hydrocode models of the shock-generated disruption of PHOs by subsurface nuclear bursts using scenario-specific models from realistic RADAR shape models. We will show 2D and 3D models for the disruption by a large energy source at the center of such PHO models ( 100 kton - 10 Mton) specifically for the shape of the Itokawa asteroid. We study the effects of non-uniform compistion (rubble pile), effective source energy, and the optimal depth of burial from the surface explosion to the central explosion.
