Deformation modeling results based on Single Fault Model using GPS data provided by Jean-.‐Philippe Avouac (California Institute of Technology and University of Cambridge) and analyzed by ARIA using GIPSY-OASIS software and JPL Rapid & Final orbits. GeoGateway produced a fault inversion that produced the new results.

Initial model of the M 7.8 Nepal earthquake as may be seen by an Interferometric Synthetic Aperture (InSAR) spacecraft such as Sentinal-1 or ALOS-2 and GPS. The model is based on USGS mechanism of a near horizontal fault and the location of aftershocks. This image shows a synthetic interferogram for a descending pass of –168°, 24 cm wavelength, elevation of 40°. Fault is 11° dip striking 295°. Maximum displacement vector is about 2.3 m. Color wrap is 24 cm per fringe.
