ALOS-2 polarimetric SAR observation of Hokkaido-Iburi-Tobu earthquake 2018
IEICE Communications Express
This paper reports prompt space-borne ALOS-2 SAR observation results of Hokkaido-Iburi-Tobu earthquake on 2018/09/06. Emphasis is placed on quick survey for disaster monitoring using fully polarimetric data. On 2018/09/08, ALOS-2 has acquired data over the disaster area. By comparison of the previous data (2017/08/26) before the earthquake, damaged areas by landslides are clearly detected. The analysis is based on the scattering power decomposition, which retrieves scattering mechanism changedoi:10.1587/comex.2018xbl0131 fatcat:hudezhd3n5a27nblkxy7gxg64u
