[HCG37-14] Geometry of surface fault ruptures of the 2016 Kumamoto earthquake and house damages
Keywords:Kumamoto earthquake, fault geometry, house damage
Severe house damages appeared in narrow zones several hundred meters from the surface fault traces, and destructive house damages were unevenly distributed and concentrated in the both ends of the main surface fault rupture as observed Mashiki town and Minami-Aso village. Along the main surface fault rupture sever house damages were locally concentrated in the places where surface fault ruptures make steps and bends, while house damages were relatively small along the areas where surface fault ruptures extends straight except for the damages on the fault traces. House damages along the surface fault ruptures with normal slip were rather small suggesting that ground shaking was not so strong.
