Abstract： This study compiles data collected through multiple channels to analyze global seismic activity and earthquake-induced disasters in 2O24.A distribution map of disastrous earthquakes in 2024 is presented，and the seismic magnitude characteristics contributing to major disaster years are examined. A comprehensive summary of earthquake-induced casualties and losses is provided， alongside in-depth analyses of major seismic disasters and key features of global seismic hazards in 2024. Global seismic activity was lower in 2O24 than in previous years，with no earthquakes exceeding magnitude 8.O and a decrease in the frequency of events above magnitude 7.0. Earthquake disasters in 2O24 exhibited distinct characteristics： light casualties，a concentration of destructive earthquakes within the circum-Pacific seismic belt， a concentrated distribution of major disasters， and clear causes of casualties. On the basis of an analysis of 2O24 earthquake disasters and seismic activity trends since the 2lst century， this study proposes targeted preventive measures and highlights key areas for future earthquake risk mitigation.
