This model of interseismic strain ( ) indicates an accumulation rate of deficit of seismic moment of Nm/yr
Mw 7.6 (2005 Kashmir EQ): 7 yr Mw 8.2 (1934 Bihar-Nepal EQ): 100 yr

6. Seismicity and Coulomb stress change due to interseismic strain
(Bollinger et al, JGR, 2004)
Seismicity coincides with the area where Coulomb stress increases by more than 4kPa/yr.
The influence of topography on the seismicity distribution show that the deviatoric stresses driving deformation are actually low, less than about 35 MPa
