“But the second one is a little more complicated. Though fracking does cause tiny tremors, the USGS scientists found no links between the process of fracking itself and the larger earthquakes that have been occurring more frequently. They did, however, notice that earthquakes have clustered around wastewater wells in Oklahoma, Arkansas, and neighboring states. Disposing of wastewater by pumping it deep into the ground is standard practice in many industries, including mining, chemical manufacturing, and oil and gas extraction, and the oil and gas industry alone operates tens of thousands of wastewater disposal wells. But the recent surge of fracking activity, which uses millions of gallons of water to crack rock deep in the ground and release natural gas, has boosted the volume of wastewater being injected into the ground.
Stresses are everywhere in the earth’s crust, Ellsworth explains, and drilling activity can affect them. Many wastewater wells actually go deeper than gas drilling wells, reaching an older layer of rock known as basement rock, where stresses and faults are more common. The high pressure used to pump water into waste wells can cause those faults to shift, and the water itself can lubricate already-stressed faults, easing their movement and making an earthquake-causing slip more likely.”

“More than 130 large dams that China is building in its western region, an area of high seismicity, are vulnerable to earthquakes or could induce earthquakes, according to a new report released by the Canadian-based environmental group Probe International. In a worst-case scenario, dams could collapse creating a tsunami that would wipe out everything in its path, including downstream dams, and cause untold loss of life and property.
To pierce the Chinese government’s secrecy over its dam-building, the Probe report overlays a Chinese map of dam locations with US Geological Survey earthquake data and a United Nations’ seismic hazard map. Probe also used Google Earth satellite images to confirm the state of completion of about one-half of the dams.
According to the report, 98.6% of the dams being constructed in western China are located in moderate to very high seismic hazard zones. The Zipingpu Dam, for example, which is now thought to have triggered the magnitude 7.9 Sichuan earthquake in 2008 that killed an estimated 80,000 people, was built in a moderate seismic zone. The force of that quake cracked the dam and shook it so severely that it sank one metre and moved 60 centimetres downstream.”

“With the ongoing crisis at its earthquake-damaged Fukushima nuclear plant, Japan is paying a heavy price for ignoring “large-scale environmental evaluations”. This is the assessment of two prominent Chinese geologists, Xu Daoyi and Sun Wenpeng, who told chinadialogue that the incident holds important lessons for China.
The two experts argue that the Japanese authorities underestimated the potential impact of deep-ocean faults and earthquakes on power plants. As a result, they failed to locate their atomic energy facilities on the country’s less vulnerable west coast and, ultimately, to avoid the radiation crisis the world has watched unfold over the past week.
There are worrying parallels in China, said Xu and Sun. But rather than focusing on the nuclear industry, their gripe is with their country’s hydropower sector – and, more specifically, thecontroversial plans to build a cascade of dams on the Nu River, China’s last great waterway without large-scale hydropower and the focus of an animated public campaign.”

“The last four months of 2010, nearly 500 earthquakes rattled Guy, Arkansas.  The entire state experienced 38 quakes in 2009.  The spike in quake frequency precedes and coincides with the 100,000 dead fish on a 20-mile stretch of the Arkansas River that included Roseville Township on December 30. The next night, 5,000 red-winged blackbirds and starlings dropped dead out of the sky in Beebe.  Hydraulic fracturing is the most likely culprit for all three events, as it causes earthquakes with a resultant release of toxins into the environment. 
A close look at Arkansas’ history of earthquakes and drilling reveals a shocking surge in quake frequency following advanced drilling. The number of quakes in 2010 nearly equals all of Arkansas’ quakes for the entire 20th century. The oil and gas industry denies any correlation, but the advent of hydrofracking followed by earthquakes is a story repeated across the nation. It isn’t going to stop any time soon, either. Fracking has gone global.
Hydraulic fracturing (fracking) pumps water and chemicals into the ground at a pressurized rate exceeding what the bedrock can withstand, resulting in a microquake that produces rock fractures.”

“Prime Minister Sheikh Hasina forewarned that earthquake could strike the capital city as the groundwater table here is going down 2-3 meters gradually due to massive withdrawal of the water.
In reply to a question from Nasimul Alam Chowdhury (Comilla-8), she said the subsiding of the underground water level is causing serious damage to geological environment and its balance. Prime Minister’s questions and answers were tabled to facilitate discussion on the President’s New Year address to the parliament. “If water level continues to go down, there is apprehension about natural calamity like earthquake,” she said, apparently referring to the presentiment coming from experts.”
