Abstract A site-specific probabilistic seismic hazard analysis (PSHA) has been carried out for the heritage city Warangal in Telangana state of Peninsular India. The Cornell–McGuire approach of PSHA has been considered to estimate the hazard. The area of influence is taken as 500 km radius. A homogeneous and updated earthquake catalogue was compiled for the considered area which was later categorized into four seismic sources (zones) considering the earthquake epicentre and geology. The seismic parameters a and b were estimated and the b value of the for the four seismic zones ranges from 0.72 to 0.97, whereas the a value ranges from 2.45 to 3.20. The results obtained are shown as uniform hazard curves and hazard maps showing the spatial variation peak ground acceleration (PGA) considering 2% and 10% probability of exceedance in 50 years. The PGA and PSA values were compared with NDMA (Development of probabilistic seismic hazard map of India, technical report of the Working Committee of Experts (WCE), National Disaster Management Authority (NDMA), Govt. of India, New Delhi, 2010) and IS 1893-1 (Criteria for earthquake resistant design of structures, part 1: general provisions and buildings, 6th edition, Bureau of Indian Standards, New Delhi, 2016). The study focussed on understanding the possibility of seismic hazard at the heritage city Warangal in Peninsular India.
