LIQUEFACTION EXTRACTION AT HINODE AREA, ITAKO CITY USING TWO-INTERFERENCE SAR ANALYTICAL METHODS

Abstract

 Monitoring the earth’s surface using earth observation satellites has the advantages of periodicity and wide-area simultaneity, and it is possible to survey earth’s surface in any area regularly. Synthetic aperturradar (SAR) can be observed under all conditions and is suitable for using during disasters that require prompt responses. Moreover, interference SAR is a method of extracting damaged areas using SAR, but interference does not often occur in steep mountainous areas. Therefore, the applicable area for interference SAR is limited. In this study, we have applied two-interference SAR analysis methods to the Hinode area in Itako city and evaluated the possibility of detailed observations. As a result, we found that it was possible to observe Hinode area in centimeters using interference SAR. In addition, it was possible to observe individual building damage.
