Large-scale natural hazards such as hurricanes, earthquakes, and floods may simultaneously trigger a series of LOC events in CPI, causing fires, explosions, or toxic cloud emissions. Cross-category hazards coupling scenarios are more complex than other coupling scenarios and could result in more severe consequences . Wang et al. also mentioned that the risk analysis of cross-category hazards coupling scenarios is more complex and difficult, as it may need interdisciplinary integration . Most of the multi-hazard coupling scenarios triggered by earthquakes show ignition probabilities that far exceed those of traditional accident scenarios . Thus, earthquake-fire is one of the most frequent cross-category hazards coupling scenarios. Moreover, a large number of studies have proved that earthquakes can seriously affect the fire resistance of engineering structures such as steel beams ,
