Simplified schematics of the distribution of hazard areas around crater growth eruption scenarios to highlight the potential complications caused by lateral relocation of explosion positions. a Hazards are evenly distributed when explosion locations are laterally fixed. b Lateral migrations ~ 1 footprint radius away from the first crater results in lateral jets through the crater wall and larger asymmetrical hazard areas. c Continued lateral migration ~ 1 radius can result in very complicated hazard areas like in shape A + B + C. d Example inclined jet produced by explosion experiments un pre-existing crater walls (Graettinger et al. 2015). e Explosion locations greater than one radius and less than 2 radii away from the previous epicenter produced larger hazard areas and compound craters
