Abstract

This paper presents our analysis of the 2022 Afghanistan earthquakes with moment magnitudes of M4.9 and M5.3 that occurred on January 17th, 2022. We used Sentinel-1 data and the interferometric synthetic aperture radar (InSAR) technique to estimate crustal deformation and map the damaged regions. These earthquakes have caused many human casualties and urban destruction. We present our analysis technique that utilizes state-of-the-art cloud processing and correction services in hazard estimation and management. The estimated crustal deformation caused by these earthquakes shows surface deformation values ranging from -16 cm to +7 cm. Moreover, we identified the damaged regions using the phase coherence difference technique. The damaged regions are mainly in rough terrain regions, which indicates the high risk of a rockslide in our study region. We utilize online services for the cloud processing of InSAR data and analysis, also, we used an online service for tropospheric delay correction which shows high reliability for the frequent need for InSAR processing which is required to establish a valid system for continuous monitoring and assessing the natural hazards such as earthquakes.
