We investigated the risk of earthquake-induced soil liquefaction on old buildings, prompted by recent devastating earthquakes such as Japan’s 0311 and Taiwan’s 0206 Kaohsiung Meinong quakes. A vulnerability analysis framework was developed using the Hyperbolic Function Method (HBF) and depth weight coefficients from Iwasaki and Ishihara’s subsidence volume grading. Focused on Banqiao District, New Taipei City, we used ArcGIS to map the potential and subsidence of soil liquefaction. A hazard degree analysis model discerns liquefaction’s impact, culminating in a risk matrix that categorizes earthquake scenarios into three risk levels. The analysis results aid in formulating adaptation strategies and norms for managing soil liquefaction risks in old buildings.
