The 25 April 2015 earthquake that hit Nepal caused destruction on a massive scale. The rupture propagated more than hundred km eastwards at 2.8 km/s (Avouac et al. 2015). High-rate GPS and InSAR data were used by Galetzka et al, 2015 and found the width of slip pulse to be approximately 20 km and its duration to be about 6 sec. Using the source model reported in Avouac et al., 2015 we have simulated ground motion at important cities of India. Peak ground displacement (PGD), peak ground velocity (PGV) and peak ground acceleration (PGA) contours are produced for use in engineering design. As the DST-IITR installed stations were not operative during this earthquake, ground motion simulations from this work will serve as an important source response evaluation of critical infrastructural facilities.
