Abstract: The earthquake monitoring system for downstream reservoirs of Yalong river basin has been built and in stable operation state. The construction and operation of the system are introduced in this paper. The system is advanced in technology and the layout of seismic stations is scientific and reasonable. Basin management, informatization, integration and real-time online reservoir earthquake monitoring are realized. The system has been running for more than five years, plays an important role in safe operation and earthquake disaster mitigation for downstream hydropower stations of the Yalong river basin.

Key words: basin, reservoir earthquake, construction, application
