Xinjian Earthquake (China) User Feedback from using the Sentinel-1 TBX

“I would like to share an interferogram of a recent earthquake of Xinjian, China, which was produced with Sentinel 1a data and ESA's Sentinel 1A toolbox. The data is quite good for capturing earthquake deformation in this rural region, given short time revisiting and short baseline. The ESA's toolbox is also very good for the processing. It's in user friendly GUI and very easy to operate” Jianbao Sun Lab. of Earthquake Dynamics, Institute of Geology, China Earthquake Administration No. 1 Huayanli Jia, Beijing, China 100029
