Deformation monitoring using the ALOS/PALSAR

Because of the higher interferometric coherence, ALOS/PALSAR data are often used for monitoring the deformation caused by the disaster events (i.e., earthquakes, volcanoes, land subsidence by water and oil pumping, land slide, etc) using the interferometric data analysis. JAXA has been a member of the international charter, and responds to the charter calls for the emergency call. In this paper we will introduce the responses to the charter call events and the data examples generated and distributed to the disaster event as the interferometric SAR products.
