The book is aimed to present the seismic hazard estimation in two seismic gap regions of Himalaya. The Deterministic Seismic Hazard Assessment (DSHA) of a region using strong motion simulation of earthquake sources is nowadays very popular. In the present book, the seismic hazard maps of NE Himalaya and Uttarakhand Himalaya based on peak ground acceleration are presented. The semi empirical strong motion simulation technique is used to calculate PGA values in a grid pattern. The semi empirical technique is further modified to estimate component wise strong ground motion. The modified...
