[MIS34-P36] Detection of crustal deformation signal and fault dislocation model associated with 2016 Kumamoto earthquake:Preliminary report by space geodesy laboratory in Hokkaido university
Keywords:Kumamoto earthquake, Synthetic Aperture Radar, Crustal deformation, Rifting system
GSI (Geospatial Information Authority of Japan) group have already reported on their website that signals of crustal deformation associated with the event using InSAR and MAI. These results have indicated deformation field caused by right-lateral slip and >30 cm subsidence at Mt. Aso. We have applied PALSAR-2 data spanning 2016 Kumamoto earthquake to InSAR and offset tracking in order to obtain robust crustal deformation signal. These data are sharing with PIXEL (PALSAR interferometry consortium on study our evolving and surface) group. Our results show near-fault 3D displacement field where is lack of data in GSI results, and also show significant shape offset at the Futagawa- and Hinagu-fault belt. We present preliminary fault dislocation model to reproduce our results.
