A major question raised was whether the earthquake was related to the impoundment of the nearby Zipingpu reservoir – or even the Three Gorges reservoir. There are a number of different views on this issue and the authors believe the ongoing discussion will emphasize the importance of the seismic safety of dams, while promoting further research on the subject.

General concepts of reservoir triggered seismicity

Seismic events have occurred near large dam sites or in reservoir areas, and may have been triggered by changes in the physical environment as a result of impounding and operation of reservoirs. … “
