“…This is consistent with the Sendai Framework's focus on disaster preparedness and its emphasis on understanding disaster risk, strengthening disaster risk governance, managing disaster risk, and strengthening preparedness for an effective response [11]. Considering the changes in seismic risk associated with urbanization is critical in improving seismic risk management capabilities and the mitigation of seismic risk [12].…”

The management of seismic risk is an important aspect of social development. However, urbanization has led to an increase in disaster-bearing bodies, making it more difficult to reduce seismic risk. To understand the changes in seismic risk associated with urbanization and then adjust the risk management strategy, remote-sensing technology is necessary. By identifying the types of earthquake-bearing bodies, it is possible to estimate the seismic risk and then determine the changes. For this purpose, this study proposes a set of algorithms that combine deep-learning models with object-oriented image classification and extract building information using multisource remote sensing data. Following this, the area of the building is estimated, the vulnerability is determined, and, lastly, the economic and social impacts of an earthquake are determined based on the corresponding ground motion level and fragility function. Our study contributes to the understanding of changes in seismic risk caused by urbanization processes and offers a practical reference for updating seismic risk management, as well as a methodological framework to evaluate the effectiveness of seismic policies. Experimental results indicate that the proposed model is capable of effectively capturing buildings’ information. Through verification, the overall accuracy of the classification of vulnerability types reaches 86.77%. Furthermore, this study calculates social and economic losses of the core area of Tianjin Baodi District in 2011, 2012, 2014, 2016, 2018, 2020, and 2021, obtaining changes in seismic risk in the study area. The result shows that for rare earthquakes at night, although the death rate decreased from 2.29% to 0.66%, the possible death toll seems unchanged, due to the increase in population.

“…These housing projects play also a critical role driving the process of urban growth. They lead to an irreversible land transformation through landscape fragmentation, shrinking of agricultural lands (Bellout et al, 2020) and an increase of natural and man-made hazards (Boughazi et al, 2014;Boughedir, 2015). As well as an enhancement in population mobility and traffic congestion, thus altering urban metabolism (Tabti-Talamali, 2018; Chaguetmi et al,2020).…”

“…Singapore. In view of increasing global development and urbanization, it will be very useful to have an earthquake prediction system to lessen the impact of an earthquake (Boughazi et al 2014;Islam et al 2015). Figure 2.3 also shows a gradual decline of earthquake precursory studies from 2012 onwards which may be attributed to a general stagnation of research in this area.…”
