Katabasis: The Three Gorges Dam: Part IV, Will It Work?
by karlcow
The dam is built to withstand earthquakes up to 7.0 on the richter scale, and the largest recent earthquakes have been below 6.0. However, filling the reservoir behind the dam creates seismic pressure which triggers earthquakes. In fact, earthquakes between 6.0 and 6.5 are expected once the reservoir is filled in 2009. One of the dams designed to hold back sedimentation farther up is subject to even worse seismic problems. “The Jinsha has bad geological conditions, and there is a more severe seismic area upriver from Xiangjiaba,” said a Chinese geologist in Sichuan. He added that near this site, dam projects “should not be encouraged.”
