Resumen:
A critical element in seismic hazard estimation is the ground motion
prediction equation (GMPE) which relates expected seismic intensity at a
point from an earthquake of a given magnitude and location. Presently
available GMPEs for plate interface thrust earthquakes along the
Himalayan arc suffer from limited number of strong motion recordings
used in their derivation. In this study we use a larger dataset,
including recordings from the 2015 Gorhka, Nepal earthquake (M-w 7.9)
and some of its larger aftershocks, to derive GMPE for earthquakes along
the Western Himalayan arc. The proposed GMPE should give more reliable
estimation of ground motion parameters at hard sites along the arc and
in Peninsular India, and at soft sites in the Indo-Gangetic Plains.
