In this study, the strain rate (SR) in grid-nodes in and around Himalaya that was computed from 1252 GPS station data, is also used. The earthquake catalogue of Himalaya between 1225 and 2017 is compiled. The active tectonic front of the Himalaya is subdivided into 14 zones between MFT and MCT, where MHT is locked. For each zone, magnitude-completeness (Mc), ‘a’ and ‘b’ values, geodetic moment rate (Mgd), seismic moment rate (Msm), moment ratio (Mgd/Msm) are calculated. It is observed that the moment ratio is 1), and long seismic hiatus for large earthquakes. Moreover, zones 2, 4, 10, 12, and 13 have un-ruptured patches of MHT and have the capacity to spawn Mw 6.75–7.95 earthquake at any point of time. The rupture generated in these zones will transgress the zone boundaries and terminate in the sub-surface Precambrian ridge systems continuing from Peninsular India below Himalaya.
