Based on Continuous GPS (CGPS) observation data of the Crustal Movement Observation Network of China (CMONOC) and the Sichuan Continuous Operational Reference System (SCCORS),we calculated the horizontal coseismic displacements of CGPS sites caused by the 2013 Lushan Mw 6.6 earthquake.The results indicate that the horizontal coseismic deformations of CGPS stations are consistent with thrust-compression rupture.Furthermore,the sites closest to the epicenter underwent significant coseismic displacements.Three network stations exhibited displacements greater than 9 mm (the largest is 20.9 mm at SCTQ),while the others were displaced approximately 1-4 mm. Based on Continuous GPS (CGPS) observation data of the Crustal Movement Observation Network of China (CMONOC) and the Sichuan Continuous Operational Reference System (SCCORS), we calculated the horizontal coseismic displacements of CGPS ​​sites caused by the 2013 Lushan Mw 6.6 earthquake.The results indicate that the horizontal coseismic deformations of CGPS ​​stations are consistent with thrust-compression rupture. Focus next to the epicenter underwent significant coseismic displacements. Three network stations show displacements greater than 9 mm (the largest is 20.9 mm at SCTQ), while the others were displaced approximately 1-4 mm.
