SEISMIC GEOLOGY

摘要：Based on ascending and descending tracks of the Sentinel—1A satellite IW model, combined with the precision orbit data provided by ESA, the differential interferogram is obtained by removing the terrain phase from the ASTEM GDEM V2 data with 30 m grid spacing. The differential interferogram is unwrapped by minimum cost flow algorithm in order to derive the precise coseismic surface displacements of the Menyuan Mw 5. 9 earthquake occurred on January 21, 2016.
