Boy, I guess nobody but me remembers the #DoctorWho serial, "Inferno"...? This is NOT a good idea!

"Ironically, enhanced geothermal uses similar fracking techniques currently used to extract oil and gas, which must be phased out if the world is to avoid climate disaster. In the geothermal version of fracking, fluid is injected deep underground, causing fractures to open up, with the liquid becoming hot as it circulates. The hot water is then pumped to the surface, where it can generate electricity for the grid."

No, this big swarn of earthquakes happening under the Pacific Ocean west of Canada's Vancouver Island isn't a sign that a big subduction quake is imminent. But the tremors do mean that scientists are about to get a good look at how new crust forms as the sea floor spreads on a mid-ocean ridge.

phys.orgRecent volcanism on Mars reveals a planet more active than previously thoughtA vast, flat, "featureless" plain on Mars surprised researchers by revealing a much more tumultuous geologic past than expected, according to a study led by researchers at the University of Arizona. Enormous amounts of lava have erupted from numerous fissures as recently as 1 million years ago, blanketing an area almost as large as Alaska and interacting with water in and under the surface, resulting in large flood events that carved out deep channels.
