Outline of Final Research Achievements

Based on the detailed interpretation of anaglyph images of 5-m-grid Digital Elevation Model made from IfSAR data, we made a detailed active fault map and marine terrace distribution map of the Philippines, one of the most earthquake-prone countries in the world. Our active fault map is far more precise and trustworthy than the present PHIVOLCS active fault map, and the marine terrace distribution map is the first nation-wide map in the Philippines. We defined eight areas with high risk of large earthquakes based on the density and extent of active faults and the former shorelines deformed by active submarine faults.
