Abstract

Studying the activity of salt diapirs is a highly complex task. Here, we addressed this challenge by utilizing eight years of Sentinel-1 satellite ascending and descending orbit data to decompose two-dimensional annual subsidence deformations in both the east-west and vertical directions. Employing statistical methods, we extracted and analyzed the pixel values of two-dimensional deformation in ten salt diapirs. Leveraging prior conclusions of activity in seven of these diapirs, we predicted and validated the activity of the remaining three diapirs with unknown activity. Ultimately, we confirmed that all three of these diapirs exhibit features indicative of activity.
