Once again: Sichuan quake highlights dam risk

The 7.0-magnitude earthquake in southwest China’s Sichuan province earlier this month and a devastating 2008 quake in the same province are likely linked to the region’s dam-building program, says expert.

Too many dams to look after

As China continues to embrace a new era of hydropower expansion, demand for dam inspection has outpaced the country’s supply of inspectors, ramping up safety fears for thousands of small- and medium-sized dams in China’s rural areas that have been “ignored”, reports Ecns.cn.

This could get complicated

Increasing demand for natural catastrophe insurance has provided the world’s largest reinsurer, Munich Re, with its biggest market in the Asia Pacific region: China. But how will Munich Re classify disasters, such as earthquakes, in a country where seismic events are a growing subject of debate as to how many are natural and how many are man-made?

Chinese geologist links recent Badong County quake to Three Gorges Dam

(December 20, 2013) High-profile Chinese geologist Fan Xiao — and the author of several reports for Probe International — notes with interest the rush by China’s state media, and the country’s official seismological agency, to dismiss a link between the 5.1-magnitude Badong County earthquake on Monday and the Three Gorges Dam reservoir. A dismissal that runs contrary to common sense and the basic facts of seismic analysis, says Mr. Fan, who believes reservoir-induced-seismicity (RIS), triggered by impoundment of the massive dam, was likely behind the recent quake and could induce stronger earthquakes in the region.

5.1-magnitude earthquake strikes Three Gorges Dam region

(December 16, 2013) A 5.1-magnitude earthquake struck a mountainous and populous area of China’s Hubei Province today, 100 kilometres from the Three Gorges Dam site. Officials have been quick to reassure the public that the dam has remained intact and is operating normally after the event, which occurred at 1:04 p.m. in Enshi Tujia and Miao Autonomous Prefecture, Badong County. Aftershocks and quake-triggered landslides are expected. What more could there be to this story?

Massive new dams remind China of human price of ‘tofu constructions’

(July 20, 2013) China is on the cusp of another dam-building binge. Nowhere is the aggressive dam push raising more eyebrows than in the country’s southwest. Last year, a report by the environmental group Probe International said of the 130 proposed dams on rivers in the region, nearly 50 per cent “are located in zones of high to very high seismic hazard.”
