The 2018 Sulawesi Island, Indonesia Earthquake: Crustal deformation detected by ALOS-2 data
Crustal Deformation Observed by Synthetic Aperture Radar (SAR)
An earthquake (Mw 7.5, USGS) occurred in Sulawesi island, Indonesia on September 28, 2018 (UTC). To measure the crustal deformation caused by this earthquake, we applied interferometric analysis using ALOS-2/PALSAR-2 data. The analysis result shows that the crustal deformation occurred in the part of the island.
