Dams and Earthquakes

Chinese media investigates dam link to latest earthquake

(April 22, 2013) China’s “First Financial Daily” investigates the hazards of reservoir-induced seismicity in the wake of the magnitude-7 Lushan earthquake.

China’s First Financial Daily interviews Chinese geologists, Fan Xiao and Yang Yong, who argue that China’s breakneck dam-building in the seismically active south-west region of China increases the risk of geological disasters. Dam reservoirs can both trigger and be damaged by seismic activity, putting populations at risk. According to Yang Yong, there are more that 100 large and small reservoirs and hydropower stations within a 100km radius of the magnitude-7 earthquake that rocked Lushan County, Sichuan, on Saturday, April 20, 2013.
