Hazard analysis of typhoon disaster-causing factors based on different landing paths: a case study of Fujian Province, China

The maximum daily rainfall, maximum wind speed, and storm surge frequency during the typhoon period were obtained based on the main landing paths of typhoons in Fujian Province, China. Methods such as the Pearson III probability distribution function, information diffusion theory, and entropy weight theory were used to analyze the hazard of the disaster-causing factors of typhoons with different landing paths. The results show that the hazard of typhoon disasters in Fujian Province gradually decreases from the eastern coastal area to the western inland area, but the hazards notably differ between different landing paths. The dominant factor affecting the hazards of typhoon disasters in Fujian Province is the typhoon rainstorm. The hazard analysis of typhoon disasters based on different landing paths can provide more specific and reliable information for the comprehensive risk assessment of typhoon disasters. Furthermore, it can provide a more scientific decision basis for the customization of disaster reduction plans in the study area.
