Key Points: • We present geodetic observations of coseismic and postseismic deformation due to the 2015 M w 7.2 Sarez (Pamir) earthquake. • Near-field postseismic deformation is dominated by shallow afterslip and possibly poroelastic relaxation at the NE end of the earthquake rupture. • Data do not show a clear signal expected of viscoelastic relaxation, indicating effective viscosity of the lower crust > 10 19 Pa s. • We investigate triggering relationships between the M7.2 earthquake and a pair of M6+ events that occurred within 1 year and 100 km of the mainshock.
