[STT54-10] Detection of slope failure using ALOS and ALOS-2 data – Application to Mt. Fuji
Keywords:SAR interferometry, Slope failure, Mt. Fuji
Our InSAR results using ascending and descending data showed the slopes opposite to radar illumination exhibits low coherence likely due to the shadow effect. Accordingly, it is possible to monitor most of slopes using either ascending or descending data. However, the western slopes of Mt. Fuji constantly showed low coherence in both ascending and descending data. This is attributed to the layover effect in ascending data and the shadow effect in descending data. Compared with ALOS and ALOS-2 data analysis, ALOS-2 results have larger high coherence areas compared with ALOS result. We also found the slope failure in the Houei crater. These results show the effectiveness of slope failure monitoring using InSAR analysis of ALOS and ALOS-2 data.
