Oil and gas activists peppered Governor John Hickenlooper with questions this weekend. At first they protested outside the St. Regis hotel, hoping to catch Hickenlooper and other democratic governors in a conference. When Colorado’s governor didn’t come out to talk, demonstrators followed him to the Aspen Institute... where Hickenlooper appeared to get flustered after a barrage of questions.
A geothermal energy plant near the Salton Sea in California taps deep underground heat from the southern San Andreas Fault rift zone. A new study ties the amount of water pulled from the ground by the geothermal plant here to the frequency of earthquakes.
The continental U.S. experiences small earthquakes every day. But over the past few years, their numbers have been increasing. Geoscientists say the new epidemic of quakes is related to industrial wastewater being pumped into underground storage wells.
Now there's new research that reveals two trigger mechanisms that may be setting off these wastewater quakes — other, larger earthquakes (some as far away as Indonesia), and the activity at geothermal power plants.
