Audio Report from Colorado Public Radio: Earthquakes in Southern Colorado linked to oil and gas production
Justin Rubinstein, a geophysicist with USGS says the rumbles are likely triggered by wastewater injection wells from drilling projects. “What we think is happening at least for some of these earthquakes is these fluids more or less are acting as a lubricant on faults in the area, making earthquakes more likely,” Rubinstein said.
The geophysicist said everywhere has faults. He is “very confident” the “majority” of earthquakes are caused by
The largest earthquake so far was a M5.3. He describe that quake as above the nuisance quakes that are, you know, like the ones in the Azle area that have caused damage to homes and property.
In the meantime, things are still rocking in the Azle area according to the seismic data HERE.

This comprehensive report covers the most recent frackquake swarm in the Azle/Reno and frackquakes in other areas and countries. It also addresses other concerns such as frackquake effects on dams. Here’s a graph showing earthquake increases in the Alberta area.
In particular, clusters of tremors have increased in areas of ramped-up tight oil activity and multi-stage hydraulic fracking, such as Brazeau County and Del Bonita near the Montana border. Landowners have also reported structural damage from tremors in Cochrane, Ponoka and Strathmore, where intense fracking has taken place. As a consequence, the government of Alberta quietly issued controls on fracking around critical infrastructure and imposed severe restrictions on activity near the Brazeau Dam after lobbying by TransAlta pressed for tighter regulations last year.

http://linkis.com/www.reuters.com/arti/qNyTg Dutch cuttin gas production/tremors REUTERS reported Jan 17 that gas production at Groningen, (Neitherlands) the largest gas field in western Europe, will be cut by about one fourth over the next three years …studies showed that there are risks and consequences, including earthquakes,” of the gas extraction in Groningen, Prime Minister Mark Rutte told reporters …
“They not only cause material damage but also serious emotional damage. The cabinet understands that people are worried.”
The Dutch set aside money to help residents repair damage from the quakes.
What an odd country. “The cabinet understands that people are worried”….and they not only acknowledge that they heard them, but they actually do something about it?…Crazy concept.
