Opak Strike Slip Fault Modeling Interpretation Using Photogrammetry Method of Drone Survey in Trimulyo, Bantul, Yogyakarta Province

Abstract The Opak fault was known as the Epicenter of Yogyakarta earthquake on May 27, 2006. This claimed more than 5,000 lives, especially in area and its surroundings. Various studies have been carried out determining defining faults. study focuses describing crush zone Trimulyo, Bantul, using photogrammetry method drone survey. equal to +256.000 m 2 with 231.159 tie points, 29.484.107 points dense cloud, 1.965.606 face 3D model, 3.08 cm/pixel resolution tiled 12.3 DEM/DTM model. interpretation showed this were found form two (2) major strike – slip that are defined Fault [4] . faults main structure controlling direction from 0° 35°.
