REVIEW OF ESTIMATION METHODS AND SYSTEMS USED TO PREDICT EARTHQUAKE CASUALTIES

Earthquake casualty estimation is key to earthquake resistance and hazard prevention planning prior to earthquakes and emergency rescue efforts after earthquakes. Scholars in the fields of earthquake engineering, geophysics, sociology, public health etc. have performed multi-perspective studies on this issue. Earthquake casualty assessment models are divided into global/regional models and local models. According to their relevant factors, they are categorized based on the appropriate seismic parameters and building fragility factors, and some researchers additionally consider the influence of secondary disasters and population characteristics. Following an introduction to the importance of earthquake casualty assessment work, traditional casualty estimation methods, and emerging methods combined with artificial intelligence, big data and spatial information technology are summarized in this review. The framework, technical foundation and application of earthquake loss estimation systems are introduced, and future development trends are envisioned.
