Regional variation of the ω-upper bound magnitude of GIII distribution in Hindukush-Pamir Himalaya and the adjacent regions: A perspective on earthquake hazard

► We investigated the regional variations of upper bound magnitude (ω) and M100. ► There is a linear relation between ω and Mmax estimated by Kijko-Sellevoll method. ► The largest ω values found in Quetta, Pamir Himalaya and Kashmir-Himanchal Pradesh. ► The spatial mapping of ω, M100 and Mmax can be used as hazard atlas.
