[SSS15-P25] LC-InSAR analysis of the Sulawesi earthquake in Indonesia
Keywords:InSAR, LC-InSAR diagram, 2018 Sulawesi earthquake, Palu-Koro fault
In this study, the authors conducted the interferometry analysis using ALOS-2 data and found out the followings:
1) A phase discontinuity lines found in the LC-InSAR diagram can be Palu-Koro fault and other small strike-slip faults around Palu-Koro.
2) In the LC-InSAR diagram, areas with low coherence are distributed in a wider range than the range where damage was caused by liquefaction. This shows the possibility that the ground change has occurred in a wider range than the extent of damage caused by liquefaction.
The authors confirmed that analysis using ALOS-2 data can identify places and scopes of disasters with extensive damages occurred not only in Japan but also in other countries.
