Monitoring of Crustal Movements Using Satellite SAR Data and Observing Volcanic Terrain Using Airborne SAR

Abstract

In 2018, A large-scale earthquake occurred directly underneath Iburi area in Hokkaido. Furthermore, several volcanos erupted in Japan with volcanic terrain changed. In this report, we introduce disaster response in 2018 by Geospatial Information Authority of Japan (GSI) using satellite SAR data for detecting crustal movements and airborne SAR data for observing volcanic terrain changes. GSI released these results of analysis via website. Also GSI provided them to various institutes and local governments for their disaster response and recovery operations.
