Abstract:

Based on a statistical analysis of the earthquake catalog for events of magnitude 5.0 and above in China in 2024,this study,in conjunction with earthquake disaster loss assessment data from the Ministry of Emergency Management and provincial earthquake bureaus(including autonomous regions and municipalities directly under the central government),provides a comprehensive summary of earthquake disaster conditions and the primary characteristics of seismic hazards in mainland China during the year. By systematically comparing earthquake disaster data from the past decade,this study examines the inter-annual variations in the frequency of destructive earthquakes and the number of casualties they have caused. Additionally,it presents an overview of earthquake-related disasters over the past 10 years,including the spatial distribution of casualties and property losses across various provinces.
