a Topography, faults, GPS velocity field with 95% confidence ellipses relative to the Eurasian Plate, coseismic horizontal GPS deformation and Sentinel-1A SAR image range in the epicenter and the surrounding area of the Jiuzhaigou earthquake. The black curved lines represent faults. The black dashed quadrilaterals represent the area covered by the descending and ascending Sentinel-1A images. The red triangles represent continuous GPS stations of the Crustal Movement Observation Network of China and the blue triangles the Beidou Ground Based Augmentation System stations. The red arrows represent the horizontal velocity field before the earthquake, and the blue arrows represent the coseismic deformation of the horizontal component. b Aftershock distribution, tectonic setting, and GPS velocity with 95% confidence ellipses relative to the Eurasian Plate
