Summary

An earthquake (M 5.9, USGS) occurred in Islamic Emirate of Afghanistan on June 21, 2022 (UTC). To measure the crustal deformation caused by this earthquake, we applied interferometric analysis using ALOS-2/PALSAR-2 data.The analysis clearly revealed the spatial distribution of crustal deformation.
