| Outline of Final Research Achievements |
In recent years, earthquake disaster management have become an urgent issue in Thailand where frequent occurrence of earthquakes caused by active faults. However, basic data for earthquake hazard assessment and damage prediction are not sufficient. Therefore, in this research, (1) extraction of ground deformation by InSAR analysis of synthetic aperture radar (SAR) images in order to understand earthquake environment, (2) geomorphologic classification and microtremor measurement to evaluate site characteristics due to strong ground motion, were carried out. Specifically, with regard to (1), the accuracy assessment of SBAS and grasp of the crustal deformation by the 2011 earthquake are carried out using InSAR analysis, and for (2), we calculated the topographical features based on the DEM for the city of Chiang Rai and created the geomorphologic classification map, and furthermore created a distribution map of the dominant period of the ground by comparison with the microtremor data.
