How do you like your frackquake ? Shaken or stirred ? Whether from an injection well or the frack itself, fracking is bound to shake you till your house falls apart. Look at the related posts at the end of the blog – frackquakes are such a pervasive problem that no government regulatory agency even wants to study them since they would have to shut down fracking to stop them
The biggest frack quake in history was in Oklahoma:
Big Oklahoma quake in 2011 likely frack quake. An unusual and widely felt 5.6-magnitude quake in Oklahoma in 2011 was probably caused when oil drilling waste was pushed deep underground, a team of university and federal scientists concluded. Associated Press. 27 March 2013.
Quake tied to oil-drilling waste adds pressure for rules. Scientists have linked Oklahoma’s biggest recorded earthquake to the disposal of wastewater from oil production, adding to evidence that may lead to greater regulation of hydraulic fracturing for oil and gas. Business Week. 27 March 2013
And the Low Countries are geting lower all the time . . .

Parts of Low Country Are Now Quake Country

LOPPERSUM, the Netherlands — Jannes Kadyk’s modest brick home suffered more than $5,000 in damage. Bert de Jong’s more stately home will need about $500,000 to get back into shape.
Both houses, like thousands of others, were damaged during recent earthquakes that have shaken the flat farmland in this area dotted with villages and tucked up against the North Sea.
The quakes were caused by the extraction of natural gas from the soil deep below. The gas was discovered in the 1950s, and extraction began in the 1960s, but only in recent years have the quakes become more frequent, about 18 in the first six weeks of this year, compared with as few as 20 each year before 2011.
Chiel Seinen, a spokesman for the gas consortium known as NAM, said the extraction had created at least 1,800 faults in the region’s subsoil.“These faults are seen as a mechanism to induce earthquakes,” he said.
The findings in the Netherlands parallel the anxiety about hydraulic fracturing technology in the United States, where several states have halted drilling temporarily, though more commonly out of fear that chemicals used in the process may pollute water sources.
This month, the New York State Assembly voted to block so-called fracking, the process in which water is blasted through rock at high pressure to extract gas, until 2015, requiring further study on its environmental impact.
This is not Haiti. The worst tremor, last August, had a magnitude of 3.4, hardly enough to cause widespread devastation. Yet the number of claims for damaged property is already in the thousands, and the company extracting the gas, a consortium of Shell and Exxon Mobil, has set aside $130 million for measures to strengthen buildings against the shocks. Yet most troubling is that experts at government agencies are predicting that the quakes will worsen, to between a magnitude of 4 and 5.
