Quake strikes Three Gorges Dam area again

(May 28, 2014) Another earthquake has struck the Three Gorges Dam reservoir region in central China’s Zigui County. No casualties have been reported so far and officials say the dam is operating normally. The 3.4 magnitude tremor which hit early Monday morning, some 23 km from the dam, follows two earthquakes of magnitude above 4.0 and hundreds of aftershocks which shook the same region in late March of this year. The events rank as significant according to Chinese geologist and environmentalist Fan Xiao, who says they are signals that the seismic threat posed by Three Gorges Dam is at its most critical stage now.

Jinping-I Dam impoundment linked to earthquakes

(February 3, 2014) Chinese geologist Fan Xiao investigates once again if the impoundment of a large dam reservoir triggered a series of earthquakes in the seismically active southwest region of China? Based on data collected by China Seismic Information (CSI), Mr. Fan says, ‘Yes’. Not only were the November 22, 2013, seismic events recorded in Sichuan, China not naturally occurring or isolated incidents, he says the region should prepare for stronger, “even destructive earthquakes” as a result of further impoundment.

On alert: RIS risk amid rash of earthquakes in China’s Sichuan-Yunnan region

(March 22, 2013) A new report, exclusive to Probe International, calls for urgent monitoring of China’s large dams in areas prone to seismic hazard. These areas may be at increased risk from dam reservoir-induced seismicity (RIS). Scientists have observed that reservoir impoundment may not only increase the risk of strong earthquakes, particularly in areas already vulnerable to high-intensity seismic activity, but may represent a more pronounced risk in the first few years after a dam is filled.
