The Luding M_S6.8 earthquake is the one which has caused the largest disaster-stricken area and the biggest death toll in Sichuan Province since Lushan M_S7.0 earthquake in 2013,which also caused a certain level of damage to buildings and fundamental facilities,and triggered extensive geological hazards. Based on the first-hand data from provincial earthquake relief headquarter and disaster investigation teams,this article processes the data and conducts an analysis on the disaster characteristics of Luding M_S6.8 earthquake from different aspects,including time series of disaster information acquisition,spatial distribution of disaster characteristics,life loss,building damage and earthquake-induced geological hazards. Through analysis,preliminary conclusions are drawn as below:①The black box period lasts for 1.5h,the statistical ratio of mortality is less than 1%,over half the amount of information on casualties is obtained within 24h,which conforms with the status of disaster information acquisition after moderately strong earthquake strikes;②Many regions are affected by the earthquake,the total sensible area is up to 816194km²,the area of seismic intensity Ⅵ and above is 19089km²,the area of seismic intensity Ⅸ and above is 280km²,the affected area equals to that of a M_S7.0 earthquake;③Damages are huge and concentrated. By the time of 5PM,September 11,2022,93 people died,25 people went missing,415 buildings collapsed,5566 buildings were heavily damaged,19890s buildings were moderately damaged,565 new earthquake-induced geological hazard spots with potential to cause harm are added to the list,92% of the places where the victims were found,68% earthquake-induced geological hazard spots and most destroyed or heavily damaged buildings are distributed in the area of seismic intensity Ⅷ and seismic intensity Ⅸ;④Secondary geological hazards such as landslide and mountain collapse are the major cause of death,the proportion of their victims(missing people included)is up to 86%.
