There is very little difference in misfit between these models (the steep, north-dipping model fits very slightly better). This is common with blind thrusts in InSAR data, and means we probably need some additional information to distinguish between the two possibilities...

...maybe some precise aftershock locations, maybe an atmosphere correction (there is some noise in the interferogram, not exactly surprising given the high topography), definitely the ascending track InSAR data (which should be available later in the week).
