Earthquake jolts Three Gorges Dam area in China
Posted on November 1, 2012
November 1, 2012 – CHINA – An earthquake measuring 3.2
on the Richter scale hit a central China region where the world’s
biggest water reservoir the Three Gorges Dam is located, though no harm
to the structure was reported. The tremor hit Zigui County of Yichang
City in Hubei Province at 3:42 am and its epicentre was located at five
km below ground, according to the China Earthquake Networks Center. No
casualties were reported though the earthquake was felt across Zigui,
state-run Xinhua news agency said. “The minor earthquake has not
affected the Three Gorges Dam, which can endure far stronger
earthquakes,” Hu Xing’e, vice head of the management bureau of the
project with the China Three Gorges Corporation said. She said that no
earthquake-triggered landslides have been reported in the reservoir area
and all power generating units and ship locks are working normally. The
dam, the world’s largest water control and hydropower project which
spans the Yangtze River, China’s longest waterway, was unaffected by the
8.0-magnitude earthquake that hit the country’s southwestern Sichuan
Province in 2008. On Tuesday, the water level of the hydropower project
reached its designed full capacity of 175 metres in a storage test that
allow experts to observe, research and validate the dam’s original
design and to test its hydropower turbo-generators. The test marked the
third round of the full-capacity storage test conducted since 2010.
“Wednesday’s earthquake was a shallow-focus earthquake rather than a
structural one,” said Zhang Shuguang, head of the project’s management
bureau. “It was not very destructive.” Zhang said the earthquake could
have been triggered by water pouring into caves or the excavation of
coal mine shafts in the region. Since the dam started to hold water in
2003, about 19,000 earthquakes, most of which have been slight or
ultra-slight, have been reported in the reservoir region, according Niu
Xinqiang, head of the Yangtze River Institute of Survey, Planning and
Design. “No structural earthquake has been reported,” he said. “The
frequency of earthquakes and landslides in this region has been
lessening over the past years,” he said. However, critics of the dam
allege that most of the tremors were caused by the weight of the mammoth
water storage. –DNA India
