Abstract:Gansu Province, one of China's provinces with high seismic intensity, has made notable progress in the informatization of earthquake disaster defense in recent years. However, technical systems for earthquake disaster defense at the municipal and county levels remain underdeveloped, resulting in issues such as ineffective resource integration across the province and limited data information services. Based on the earthquake disaster risk survey in Gansu Province, this study aims to develop a comprehensive earthquake disaster defense service platform at the provincial, city, and county levels. The platform integrates the display, query, and service of data related to earthquake hazards, disaster-bearing bodies, and earthquake disaster risk assessments. It also facilitates the unified aggregation and delivery of risk survey results across the three levels. Through various formats such as web pages, maps, and statistical charts, the platform provides informatization services for earthquake disaster risk prevention and control across Gansu Province. It aims to fully satisfy the operational requirements of earthquake departments at all levels and comprehensively enhance the seismic damage prevention and control capabilities across the entire province.
