| Abstract | In the past decade, a wide range of natural and human hazards like earthquakes have been increasing in Japan. In this research study, remote sensing has utilized for seismic examination with the initial appearance of satellite images and GPS positioning, such as interferometric SAR (InSAR). GPS gives exact and precise location data like speed, track, bearing and separation of target items after an earthquake. The GPS and other remote detecting procedures with GIS can measure the surface displacement by using SAR and GNSS data of Kumamoto Earthquakes 2016, Japan. The study focuses on a comprehensive analysis of the movement of the land surface due to earthquakes. This research mainly dealt with the distribution of significant earthquakes around the region of Kumamoto and its main features with seismotectonic settings of Japan reviewed. The map generated of coherence & Interferogram for earthquake detection. Finally, the InSAR and GPS displacements validated with government report. In this research study, it concluded that the GPS is more accurate with InSAR when it compared with the government information finally It is more useful for measuring the slow movement of low intensity of the earthquake, and detection of displacement losses in the affected area. Key Words: Earthquakes, DEM, Geohazards, InSAR, Interferogram, GPS |
