چکیده مقاله:
Earthquakes are one of the most important environmental hazards, which have usually been associated with the human and financial damages. In addition to its effects on residential areas, earthquake causes displacements and changes in the ground's surface. Iranian plate is located in the convergence zone of the Arabian plate in the southwest and the Eurasian plate in the northeast; therefore, it is a tectonically unstable area. The earth's deformation and the subsidence resulting from the destructive earthquake occurrence have been as the most important natural hazards in this plate.Several methods are used to study the effects of natural hazards on the land and settlements. Radar interference technique is one of the practical methods in investigating and measuring the amount of displacement. In recent years, many space sensors have been collecting data from the surface of the earth, one of the most successful of which is the Sentinel project. Sentinel-۱ is the radar section of the Sentinel project, which captures images of the Earth's surface at intervals of several days and is therefore suitable for monitoring surface changes and estimating the amount of earth movement using the radar interferometry method. In this article, the deformation related to the March ۱۶, ۲۰۲۲ Kookhord-Bastak earthquake (Mw۶) in the Hormozgan province is measured. The results show ۱۹ cm of subsidence and ۱۴ cm of uplift along the fault plane and around area during the earthquake.
