Earthquake induced soil liquefaction poses a significant threat to buildings and infrastructure, as evidenced by numerous catastrophic seismic events. Existing approaches of regional liquefaction hazard assessment predominantly rely on deterministic analysis methods. This paper presents a novel Probabilistic Liquefaction Hazard Analysis (PLHA) framework based on Monte-Carlo (MC) simulations to mitigate future seismic risks associated with liquefaction. The proposed procedure requires only publicly available data, offering accessibility and applicability in resource-constrained settings. A key feature of the procedure is its ability to deal with uncertainties in earthquake and soil parameters using distribution functions. Liquefaction potential is assessed through parameters such as Liquefaction Potential Index ( LPI ) and Liquefaction Severity ( L S ). The procedure is implemented in MATLAB as part of a broader probabilistic risk assessment framework for developing countries. The developed procedure is applied to the high risk city of Adapazari, Türkiye; an area lacking prior PLHA studies. Results are validated against observed liquefaction data from a simulated scenario event of the 1999 Kocaeli earthquake. Probabilistic liquefaction hazard maps are generated for the study area and the entire Marmara region in terms of LPI and L S . A novel aspect of this work is the integration of a time-dependent Probabilistic Seismic Hazard Analysis (PSHA) model into the PLHA framework. Results are compared with those predicted using the Poisson model for the Marmara region. Findings demonstrate that the developed PLHA procedure offers a robust and flexible tool for predicting seismic liquefaction hazards, providing valuable insights for loss estimation and risk mitigation planning.

地震引起的土壤液化对建筑物和基础设施构成重大威胁,许多灾难性地震事件都证明了这一点。现有的区域液化危险性评价方法主要依赖于确定性分析方法。本文提出了一种基于蒙特卡罗(MC)模拟的新型概率液化危害分析(PLHA)框架,以减轻未来与液化相关的地震风险。拟议的程序只需要公开可用的数据,在资源有限的情况下提供可访问性和适用性。该程序的一个关键特征是它能够使用分布函数处理地震和土壤参数中的不确定性。液化潜力通过液化潜力指数(LPI)和液化严重程度(ls)等参数进行评估。该程序在MATLAB中实现,作为发展中国家更广泛的概率风险评估框架的一部分。所开发的程序应用于斯里兰卡阿达帕扎里市的高危城市;一个缺乏先前PLHA研究的领域。结果与1999年Kocaeli地震模拟情景事件观测到的液化数据进行了验证。根据LPI和ls为研究区和整个马尔马拉地区生成了概率液化危险图。这项工作的一个新颖方面是将时间相关的概率地震危害分析(PSHA)模型集成到PLHA框架中。结果与泊松模型在马尔马拉地区的预测结果进行了比较。研究结果表明,开发的PLHA程序为预测地震液化危害提供了一个强大而灵活的工具,为损失估计和风险缓解规划提供了有价值的见解。
