A Study on Classification of Landform Based on SRTM-3 for Estimation of Site Amplification Factors in Metro Manila, Philippines

Abstract eng:
Developing countries do not necessarily have to use detailed and precise method in estimating earthquake damage such as Japan. Considering cost and time, it can be more important to choose quick and accurate methods and determine where to input limited resources rather than to estimate detailed earthquake damage. From this point, we proposed landform classification based on Digital Elevation Model and examined validity of proposed method. However, since there was no data such as Digital Elevation Model based on the topography map produced by measurement, applicable regions were limited. Thus, we investigated applicability of SRTM-3 of NASA which covers most overpopulated areas of the earth for landform classification and site amplification factors in Metro Manila, Philippines. The results showed great possibility to be used in areas where earthquake damage estimation has been seldom executed.
