This contains GNSS and InSAR data used in the publication "Constraints on the geometry and frictional properties of the Main Himalayan Thrust using co-, post- and interseismic deformation in Nepal". GNSS data come as separate text files for east and north displacements and errors. Each text file consists of a number of columns. Each file has 40 columns, where the first column is time in decimal years after the Gorkha earthquake and the following columns correspond to each GNSS station. The time series are those obtained after the removal of "non-postseismic" deformation such as linear and sinusoidal terms The InSAR data are in the form of GMT GRD files at 200m resolution. Data are from Sentinel-1a track 19 and are a derived work of Copernicus data, subject to the ESA use and distribution conditions. The name of each GRD file is as follows: t19_{date1}_{date2}_hgt_ramp_200m.grd. Date 1 and date 2 are the dates of the two images used to make each interferogram.
