Emergency observation and its analysis using ALOS-2 PALSAR-2 in 2015

摘要

Advanced Land Observing Satellite-2 (ALOS-2, "DAICHI-2") performed various emergency observation with its Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) in Asia in 2015. Especially for corresponding to the emergency request from Sentinel Asia related to the Mw 7.8 Gorkha Nepal Earthquake 2015, PALSAR-2 successfully detected not only the crustal deformation but also the avalanches and local displacements. In this presentation, we describe these performances, analysis and the other emergency observations.
