AbstractA M6.2 earthquake （ 35.7∘N. 102.79∘E ） occurred at 23：59 on December 18，2023， in Jishishan County，Linxia Prefecture， Gansu Province， China. The waves spread widely causing extensive casualties and damage to buildings. This study was conducted to analyze the associated disaster characteristics.Theresults showed that the earthquake occurred onsedimentary strata late at nightin winter intheborder area between the Loess Plateau andthe Qinghai-Tibet Plateau within the Yellow River Basin. The source of the earthquake was shallow，and it was intense and destructive. Buildings in the area have low fortification levels，ifany，and the population density within the earthquake area is dense， resulting in heavy casualties and significant property loss.Suggestions were made following the earthquake disaster response and the level of earthquake-resistant buildings has been appropriately improvedand disaster prediction and the emergency response capacity enhanced. Future site selections for housing should avoid fault and river impact siltation areas.Inthe future，disasterareas willbe more pronetolandslides，collapses，debris flows，andother geological disasters， especially during the rainy summer season.
