Earthquakes, though categorized as low-frequency disasters, can unleash substantial devastation, resulting in injuries, fatalities, and structural collapses. This research endeavors to construct a city model for Chiang Mai, with the goal of assessing earthquake-induced impacts and damages. Termed the "Catastrophe Model", this initiative encompasses three primary components. The first phase entails building a comprehensive database and conducting field surveys to gather precise building footprints and detailed structural information. Currently, our project has successfully surveyed 4,118 sample Authors: Bhuddarak,,Charatpangoon;Benjapol,, Pasutarat;Nuttida,, wongyai;Nattapon,, Trumikaborworn;Panon,, Latcharote;Chayanon,, Hansapinyo;Pennung,, Warnitchai.
