EPA releases final report on disposal well-induced seismicity
Natural Gas Intelligence
The U.S. Environmental Protection Agency has determined that although conclusive proof linking oil and natural gas disposal wells and earthquakes at injection sites across the country is difficult to demonstrate, a relationship is undeniable. In its final report on the topic, the agency settled on a list of the common characteristics of induced seismicity, culled from case studies in four states. It advised state regulators to manage Class II underground injection wells in a proactive and cautious manner.

Carbon 'burped' from oceans helped end ice age
Carbon released from oceans may have warmed the Earth, ending the last major ice age, new analysis reveals. University of Southampton researchers studied fossilized plankton, revealing that oceans were more acidic between 16,000 and 7,500 years ago than they are today. This effect may have been driven by carbon rising from deep beneath the surface of the water, driven by currents. These releases may have taken place in both the eastern equatorial Pacific Ocean and the Southern Atlantic Ocean.
Geologists find unprecedented 85 million-year-old reptile remains
The Jerusalem Post
The 85-million-year-old remains of a large carnivorous, seafaring reptile have been discovered in the South, making them the oldest fossils ever found in Israel, researchers announced on Feb. 10. Dr. Sarit Ashckenazi-Polivoda — a geologist who specializes in micropaleontology at the Dead Sea and Arava Sciences Center and analyzed the creature's remains — described the finding as unprecedented.

Virginia quake may have been most widely felt in US history
A new report issued Feb. 10 from the U.S. Geological Survey says the August 2011 earthquake in Louisa County, Virginia, may have been the most widely-felt in U.S. history. The 5.8 quake centered in Mineral was the largest in the Eastern U.S. since an 1886 quake in South Carolina, the report said.
Canyon carved by three short, savage floods
The Jokulsargljufur canyon, 28 kilometers long and up to 100 meters deep, is home to Europe's most powerful waterfall. By analysing the chemistry of rocks in the canyon's walls, the researchers constructed a timeline of how the canyon was shaped over time. Most changes seem to have taken place during three brief but brutal periods. Interestingly, these key flooding events occurred two, five and nine thousand years ago — separated by millennia of relative stability.
How to turn carbon dioxide into rock and bury it forever
What do we do with a problem like carbon dioxide? We want to remove the excess from our atmosphere, but how? In Iceland, geologists are burying the greenhouse gas with water, so that basic chemistry can turn it into solid rock inside what The New York Times calls "a geological soda machine."

Satellite with Scripps-designed Earth-observing science payload set for launch
Scripps Institution of Oceanography
A satellite that will be positioned between Earth and the Sun to provide a comprehensive view of our home planet is scheduled for launch tomorrow. The scientific objectives and instrumental payload were originally proposed and designed by researchers at Scripps Institution of Oceanography, UC San Diego. The NOAA-led Deep-Space Climate Observatory will measure the solar energy reflected back to space by Earth as well as the infrared radiation emitted by the planet. Such observations are essential to determine Earth's energy budget, which is the fundamental driver of climate.
Why Iceland is rising so fast
Iceland is rising at a faster pace as global warming melts the island's ice caps, scientists say. The speed of this rise is among the fastest rates at which the crust of the planet is rising, "and may continue to get faster every year," lead study author Kathleen Compton, a geoscientist at the University of Arizona in Tucson, said.
The great porphyry copper deposits of Arizona
Geology For Investors
Porphyry Copper deposits are the planet's largest source of copper and those of Arizona are among the great mineral endowments of the world. Mining Camps like Bisbee, Ray, Globe-Miami (Morenci) have produced for over a century inspiring songwriters and explorationists alike, and deposits like San Manuel — Kalamazoo have proven critical to our understanding of how these deposits form.
Mars rover on a 'walkabout'
Curiosity, the Mars traveler, has become Curiosity, the field geologist. The rover, packed with scientific sampling, testing, measuring and photography equipment, is at the base of Mount Sharp, working a light-toned outcrop of rock called Pahrump Hills. The rover has been here for several weeks, completing what geologists call a walkabout — doing elemental analysis and close-up examination of selected locations with several of its instruments. It is now in the final stage of its work in this area, which is drilling.
