This study presents a comprehensive open probabilistic seismic risk model for India. The proposed model comprises a nationwide residential and non-residential building exposure model, a selection of analytical seismic vulnerability functions tailored for Indian building classes, and the open implementation of an existing probabilistic seismic hazard model for India. The vulnerability of the building exposure is combined with the seismic hazard using the stochastic (Monte Carlo) event-based calculator of the OpenQuake engine to estimate probabilistic seismic risk metrics such as average annual economic losses and the exceedance probability curves at the national, state, district, and subdistrict levels. The risk model and the underlying datasets, along with the risk metrics calculated at different scales, are intended to be used as tools to quantitatively assess the earthquake risk across India and also compare with other countries to develop risk-informed building design guidelines, for more careful land-use planning, to optimize earthquake insurance pricing, and to enhance general earthquake risk awareness and preparedness.

印度概率地震风险评估

本研究为印度提供了一个全面的开放概率地震风险模型。提议的模型包括一个全国性的住宅和非住宅建筑暴露模型、一系列为印度建筑类别量身定制的分析地震脆弱性函数，以及印度现有概率地震危险模型的开放实施。使用 OpenQuake 引擎的基于随机（蒙特卡罗）事件的计算器将建筑物暴露的脆弱性与地震危害相结合，以估计概率地震风险指标，例如年均经济损失和国家、州、区级、分区级。风险模型和基础数据集，以及在不同尺度计算的风险指标，
