The paper describes the procedure employed for developing a new earthquake zone map of India as part of the seventh revision of the Indian Earthquake Standard IS 1893 (Part 1). This new zone map is based primarily on a probabilistic earthquake hazard analysis performed at a grid spacing of 0.1°×0.1° in longitudes and latitudes of the entire country. But, for grid locations with small probabilistic hazard estimates, a minimum level of hazard has been estimated deterministically for the most likely maximum magnitude of an earthquake on the nearest mapped fault. Based on the results, the Indian landmass is grouped into five zones, designated as ‘earthquake zones II, III, IV, V, and VI.’ The peak ground accelerations corresponding to a return period of 2475 yr in these zones are estimated as 0.15, 0.30, 0.45, 0.60, and 0.75g, which also include the site amplification effect. Common normalized response spectra are recommended for all five zones, one for each of the three different site soil conditions, as an interim measure. [ABSTRACT FROM AUTHOR] |
