Monitoring the coseismic deformation of LAquila earthquake using D-InSAR technique
The Mw=6.3 LAquila earthquake, taking place on 6th April 2009 in Italy, caused severe surface deformation. This paper described that the differential interferometric SAR (D-InSAR) technique and ENVISAT ASAR data were used to detect the LAquila co-seismic deformation fields. Firstly it introduced the basic principle and data processing flowchart of D-InSAR. Then it introduced the ENVISAT ASAR data and SRTM DEM. And it selected 3 interferometric pairs. It illustrated the procedure of two-pass InSAR data processing. Then it got the earthquake coseismic deformation field. Through interpreting and analyzing the coseismic deformation fields in detailed, it got the maximum deformation about 23cm in LOS direction. At last, it got some valuable conclusions in monitoring the earthquake deformation using two-pass D-InSAR technique. The test proves that SRTM OEM can be used in two-pass DlnSAR for monitoring the earthquake deformation.
