A 5km-long surface fault rupture appeared during 2013 Bohol earthquake (M 7.1) in the Philippine. We took low-altitude air-photos of the ruptures using a small UAV, and made 3D images and contour maps by SfM software. This survey method is a low-cost, easy and effective method for mapping for quick respond field work for unexpected large earthquake damage especially in remote areas in under developing countries.
