Seoul’s landslide risk is increasing as climate change drives higher and more irregular rainfall. From 1961 to 2022, annual rainfall in Seoul rose by 3.5 mm per decade, reaching a record 1,775 mm in 2022, with localized downpours amplifying landslide vulnerability. Analysis using a physical model reveals a 12.9% rise in landslide risk since 2010, with a projected 31.5% increase by 2100. However, current landslide risk maps lack updated geological data and fail to account for Seoul’s changing rainfall patterns. To improve landslide prediction, a comprehensive data management system is needed, ensuring frequent updates and cross-agency integration. In mountainous areas with limited geotechnical data, targeted field surveys, including drilling and seismic tests, would enhance model accuracy. Additionally, legislative gaps in landslide management should be addressed by revising the "Seoul Metropolitan City Landslide Vulnerable Area Designation Committee Ordinance" and introducing a new ordinance tailored to Seoul’s unique conditions. These steps will equip Seoul with policies to better respond to evolving climate patterns, enhancing landslide resilience and protecting communities.
