Abstract. China's earthquake emergency response system has been improved by lessons learned from multiple earthquakes. This paper focuses on the Ms7.0 earthquake that occurred in Jiuzhaigou County, Sichuan Province, China, on 8 August 2017 and assesses the emergency response activities of all levels of government as well as various departments, rescue teams, enterprises and public institutions and social organizations. The emergency response is compared to other large earthquakes that occurred in China in recent years. The lessons learned from these experiences can inform the emergency response to future disasters. The characteristics of the Jiuzhaigou earthquake and the emergency responses after the event are analysed. The response level and resource mobilization were appropriately adjusted as the disaster developed, and various departments worked together to conduct multi-sector joint rescue efforts. Additionally, professional rescue forces and participating social organizations were more rationally mobilized than during past earthquake emergency responses. A set of effective disaster relief command and coordination mechanisms was established to facilitate cooperation between multiple departments and social organizations under the leadership of the local government. Finally, new and more effective technologies played an important role in the emergency response and rescue efforts following the earthquake.
