Consistency test of surface deformation determination using Sentinel-1A and Sentinel-1B images for the 2018 Oaxaca earthquake

Abstract

By the launch of Sentinel-1B, a new satellite has become available for InSAR determination of surface deformation apart from Sentinel-1A. The two missions are essentially identical, which were planned to reduce the repeat time of imaging. Even so, it is important to analyze the consistency of the data each satellite can provide. In this study, the 2018 Oaxaca earthquake has been processed using images of these satellites independently, and based on that a comparison of their solution has been provided.
