More oil and gas drilling, more quakes

San Francisco Chronicle: The last three years have seen an explosion in oil and gas drilling in the central and eastern United States. They`ve also seen a steep increase in the number of earthquakes rattling rattling those parts of the country. And that`s probably not a coincidence, according to a new report in the journal Science. In November, 2011, a series of earthquakes that some researchers link to water disposal wells from oil field operations damaged homes in Oklahoma. The report from a U.S. Geological Survey...
Distant Quakes Trigger Temblors in the Oil Patch: Study

Daily Climate: Wells filled with waste injection fluids at oil and gas fields across the United States are at risk of small earthquakes triggered by larger temblors across the globe, according to a new study published Thursday. Waste injection wells are on the rise as domestic energy production soars and companies increasingly use water and chemicals to unlock natural gas from shale or force oil from wells, a process known as hydraulic fracturing, or fracking. As oil and gas industries pump waste into sub-surface...
Distant seismic activity can trigger quakes at 'fracking' sites

Reuters: Powerful earthquakes thousands of miles (km) away can trigger swarms of minor quakes near wastewater-injection wells like those used in oil and gas recovery, scientists reported on Thursday, sometimes followed months later by quakes big enough to destroy buildings. The discovery, published in the journal Science by one of the world's leading seismology labs, threatens to make hydraulic fracturing, or "fracking," which involves injecting fluid deep underground, even more controversial. It comes...
