“…As the application of conventional vulnerability assessment methods on a large scale requires information that is not readily available, they proposed assessing the ability of available data from national census for a region to estimate building vulnerabilities and modeling seismic damage for specified seismic intensities. More recent studies have demonstrated the efficiency of using machine learning techniques in seismic-risk engineering to solve the aforementioned time and resource issues (Chi et al, 2020; Hegde and Rokseth, 2020; Karmenova et al, 2020; Mangalathu et al, 2020a; Sajedi and Liang, 2020; Salehi and Burgueño, 2018; Sun, 2019; Zhang and Burton, 2019; Zhao et al, 2020). Xie et al (2020) summarized the ongoing research on the application of machine learning methods in earthquake engineering; they concluded that the implementation of machine learning in earthquake engineering is still in its early stage and needs further investigations.…”

Assessing post-seismic damage on an urban/regional scale remains relatively difficult owing to the significant amount of time and resources required to acquire information and conduct a building-by-building seismic damage assessment. However, the application of new methods based on artificial intelligence, combined with the increasingly systematic availability of field surveys of post-seismic damage, has provided new perspectives for urban/regional seismic damage assessment. This study analyzes the effectiveness and relevance of a number of machine learning techniques for analyzing spatially distributed seismic damage after an earthquake at the regional scale. The basic structural parameters of a portfolio of buildings and the post-earthquake damage surveyed after the Nepal 2015 earthquake are analyzed and combined with macro-seismic intensity values provided by the United States Geological Survey ShakeMap tool. Among the methods considered, the random forest regression model provides the best damage predictions for specified ground motion intensity values and structural parameters. For traffic-light-based damage classification (three classes: green-, amber-, and red-tagged buildings based on post-earthquake damage grade), a mean accuracy of 0.68 is obtained. This study shows that restricting learning to basic features of buildings (i.e. number of stories, height, plinth area, and age), which could be readily available from authoritative databases (e.g. national census) or field-surveyed databases, yields a reliable prediction of building damage (4 features/3 damage grade accuracy: 0.64).
