Chinese Dam blamed for recent earthquakes

The earthquake that took place in China could be related to the construction of the Three Gorges Dam, warns an environmental hydrogeologist of Cardiff University.

Dr Yuesuo Yang, who has interdisciplinary interests in science and engineering, generic groundwater and related ecological issues and applied environment-health studies, told The Archer: “The earthquakes that have taken place during the past decade must be related to the construction of the Three Gorges Dam.”

Dr.V.P Jauhari wrote in a paper for the World Commission on Dams and explained how dams could cause earthquakes: “ The most widely accepted explanation of how dams cause earthquakes is related to the extra pressure created in the micro cracks and fissures in the ground under and near a reservoir.

“When the pressure of the water in the rocks increases, it acts to lubricate faults which are already under tectonic strain, but are prevented from slipping by the friction of the rock surfaces.”

Chinese citizens have expressed their doubts on the cause of this earthquake on Weibo, the equivalent of Twitter in China. Some of them have pointed out the construction of the Three Gorges Dam should be blamed for the earthquakes that hit Sichuan Province in recent years.

Most of their messages have been deleted by web managers of Weibo due to its sensitivity, as people cannot search words like earthquake and Three Gorges Dam on the platform any more.

Wales Red Cross told The Archer: “We have emergency guides for floods and snows in Wales and earthquakes are quite rare in Wales.” But Wales Red Cross suggests people to look at their website and learn how to prepare for a disaster.

The earthquake that hit Yaan in Sichuan Province of China has killed at least 193 people.
