Insar data


I’m working in a school project in which I need to see the deformations that the 2017 earthquake made to the land in Seoul, korea. I have found many SAR images before and after the earthquake on this website, now I want to see the land subsidence that happened between the two images. I heard that inSAR technique can do that but I never used it before. What is the easiest tool I can use to generate inSAR image to see the land subsidence, and is it possible to learn the inSAR technique in short time? I don’t want to do a complicated thing I just want to know how much subsidence happened after the earthquake, where should I start?
