There was a serials of surface rupture caused by the earthquakes around Ruei-Suie area. Chung(2003) demonstrate that 1951 rupture may separate to three segments, Ruei-Suie,Yuli and Chihshang segment. The maximum displacement of Ruei-Suie segment about 2 meters. Most of the studies are focus on the description in 1951 earthquake, to characteristics of near-fault activity and deformation, however the surface rupture of 1951 earthquake did not discuss in details. By the advancing technology in recent years, the serials of the remote-sensing images taken in different periods have been wildly applied for multi-displine, especially for surface and environmental change analysis. The earliest aerial photographs were taken by the U.S. Air force during the 1940s in Taiwan. Nevertheless, because of absent of aerial information, difficult to acquire and image damages, it’s difficult to achieve and for application. In this study, the aerial images were taken by the U.S. Air force and TW Air force during 1940-1960. The Real Time Kinematic GPS equipment has been used accordingly to measure the ground reference points to calculating the exterior orientation parameters of each image. The photos is thus been orthorectified by means of the Airborne LiDAR data. Finally, the 1951 Ruei-Suie earthquake deformation is analyzed by means of Particle Image Velocimetry (PIV) sub-pixel matching technique and feature point measurements base on the orthorectified images. The results shows 2008’s DTM is better than 5M_DEM official data. The most important of DTM construction based on historical aerial photography is the definition of image. It’s difficult to calculate the coseismic displacement by PIV sub-pixel matching technique, because of the topography has been change a lot. By the feature points, it indicates Ruei-Suie fault show a left-lateral reverse fault, and the average displacement is 3.66 m , the maximum displacement is 5.77 m. 張國楨 2012 學位論文 ; thesis 112 zh-TW |

By the advancing technology in recent years, the serials of the remote-sensing images taken in different periods have been wildly applied for multi-displine, especially for surface and environmental change analysis. The earliest aerial photographs were taken by the U.S. Air force during the 1940s in Taiwan.
