The earthquake disaster emergency coordination mechanism is of great significance for improving the earthquake disaster emergency response capacity and ensuring post-earthquake disaster relief in good order. The new emergency management system has solved the problems of multiple emergency coordination entities and high costs to a certain extent,and improved the ability to respond to complex and volatile catastrophic events. However,there are still shortcomings in the ownership of command power,deep coordination,and technical support for emergency coordination research in cross regional emergencies. Based on the concept of earthquake disaster emergency coordination mechanism,in this paper we take the Beijing-Tianjin-Hebei region as an example to analyze the demand of earthquake disaster emergency coordination faced by the three regions under the new system due to their geographical proximity,lifeline engineering dependency,and economic development integration trend. We select above three key issues affecting the construction of the Beijing-Tianjin-Hebei earthquake emergency coordination mechanism and proposes solutions. We emphasize the importance of the “risk-scenario-task-demand-collaboration” research framework in scenario construction method for resolving key issues,which can effectively overcome the shortcomings of relying on interdepartmental coordination to slowly improve coordination and rescue effectiveness in the past. The proposed solutions in this paper can improve the effectiveness of future earthquake and catastrophe emergency management,and improve the comprehensive capacity of national disaster prevention and mitigation.
