We collect earthquake disaster related information and data through multiple channels on a quarterly basis,and conduct statistical analysis on global seismic activities with a magnitude of 5.0 or above since 2020,with a focus on the earthquakes with a magnitude of 5.0 or above that caused significant casualties and economic and property losses from July to September 2023. Then,we elaborate on the earthquake disasters and their impacts of typical earthquakes,summarize the main characteristics of earthquake disaster activities in the third quarter of 2023, analyze the characteristics of global earthquake activity and human casualties,and emphasize the importance of daily seismic fortification and cultivating emergency avoidance awareness in hazard mitigation.
