Landslide Susceptibility Analysis by Type of Cultural Heritage Site Using Ensemble Model: Case Study of the Chungcheong Region of South Korea

The damage caused by landslides is increasing worldwide due to climate change. In Korea, damage from landslides occurs frequently, making it necessary to develop effective response strategies. Presently, the consideration of cultural heritage sites in these strategies is insufficient. The purpose of this study is to analyze the spatial relationship between cultural heritage sites in the Chungcheong region of Korea and some areas susceptible to landslides. The Chungcheong region has many historically important cultural heritage sites. There are various relics in landslide susceptibility areas (LSAs), with sites associated with religion (171), history (148), traditional architecture (138), tombs (92), educational institutions (47), landscapes (20), and irrigation facilities (2). Additionally, the percentages of LSAs with different types of cultural heritage sites were investigated and found to be as follows: landscapes (37.03%), tombs (27.72%), religion (26.06%), history (25.32%), education (25.26%), traditional buildings (24.74%), and irrigation facilities (18.75%). According to the judgment process of prioritizing prevention measures, sites associated with history should be given the highest priority to prevent landslide damage, followed by those associated with religion. The approach and results of this study are expected to help prevent landslide damage in cultural heritage sites by aiding the development of decision-making strategies.
