Abstract

The study area, represents a boundary collision zone between the Indian and Euroasian plates. Except for events that have been clearly associated with the underthrusting of the Indian plate, the data reported indicate a layer of concentrated seismicity in the lower crust at a depth range of 30 to 40 km. The lithosphere rheology was assessed on the basis of the frictional failure in the brittle regime, and power-law steady-state creep in the ductile regime. Rheological profiles were constructed for a 1-D crustal structural and thermal model. The rheological stratification of the lithosphere was compared with the earthquake depth distribution which indicated a reasonable confinement of seismicity to brittle horizons. -from Authors
