In this paper we design a localized earthquake emergency work platform for Beijing by comprehensively using Beijing-Tianjin-Hebei basic geographic data,localized earthquake disaster rapid assessment model,localized auxiliary decision templates,and offline rapid assessment and thematic maps generation technology. Based on Android mobile terminal,The platform realizes remote earthquake rapid trigger,rapid disaster assessment,auxiliary decision-making,automatic information push,emergency command and dispatch,daily operation management,and comprehensive information query. The platform provides scientific and efficient information service for earthquake disaster emergency command and decision-making for Beijing,which has been applied in multiple earthquake events and proved to have important practical application value in earthquake emergency disposal.
