How big is the threat of Wenchuan earthquake in Sichuan to Fiona Fang?

The magnitude of historical earthquakes is properly weighted, and the maximum credible earthquake in the reservoir area is determined to be about 6. The induced earthquakes in fairy mountain and Jiuwanxi fault zone (from dam site 18 km) are only distributed within 5 km of the reservoir and its periphery, and the focal depth is mostly within 5 km, and rarely exceeds 10 km. There is a certain correlation between focal depth and reservoir capacity. Generally speaking, the greater the reservoir capacity, the deeper the focal depth. The National Seismological Department has a clear definition of reservoir-induced earthquake: "Earthquakes on the upstream and downstream banks of the dam within the range of Fiona Fang 10 km are called induced earthquakes. Earthquakes beyond this range are not considered to be reservoir-induced earthquakes. "
