Determination of Crustal Deformation around Afar (Ethiopia) Using Sentinel 1SAR Interferometry

Andnet Na, Daniele Perissinb, Tulu Beshac

This study is conducted to analyze the crustal deformation pattern at a locality in the Afar region which is geographically located in northern part of east African rift valley between 13° 20‘ N to 13° 50‘ N latitudes and 40°30‘ E to 41°00‘ E longitudes, within the triple junction that is formed by the Arabian, Nubian and Somalian diverging plates. The region is one of the active volcanic areas in the world, where the episode of plate movement resulted in seafloor spreading that causes the earth’s surface to deform in the form of surface cracking, sliding, subsiding and faulting. Presently this dynamic process of earth’s deformation in space and time can be accurately detected by satellite space geodetic observations.
