From EARTH magazine, June 30, 2016 -- Last summer, while the abandoned Gold King Mine in Colorado was being studied for acid mine drainage, the earthen plug blew out, releasing millions of gallons of acid mine water into the Animas River, which eventually drains into the San Juan and Colorado rivers and ultimately Lake Powell. The images were startling, but this event added momentum to the national dialog on remediating abandoned mine lands. EARTH Magazine explores the role geoscience plays in this process.

From EGU, April 21, 2016 -- The climate of our planet is changing, and the Earth is warming up. World leaders have discussed whether we should limit the average temperature increase in our planet to 1.5°C or 2°C. There’s only half a degree of difference between these two temperature limits, but scientists have now discovered that they would each have very different consequences for our planet.
From EARTH Magazine, June 3, 2016 -- As the U.S. celebrates National Oceans Month in June, scientists who study the seafloor are excited because they believe that humans will end this century with a far better view of our seafloor than at any other time in human history. Geoscientists have been mapping land on Earth, and even other planets in our solar system, in high definition for years, but the picture of the ocean floor has remained blurry for the most part. But with advances in engineering, what lies beneath is starting to come into much better focus.
From EARTH Magazine, June 21, 2016 -- In March 2014, 43 people were killed when 7.6 million cubic meters of mud and debris violently engulfed a portion of Oso, Wash., after a period of heavy rain. The region where this occurred is characterized by impermeable clay and silt deposits, sometimes measuring more than 200 meters thick, which formed 16,000 years ago when an ice sheet covered the region. These deposits and the addition of a wet, rainy climate makes the Stillaguamish River Valley ripe for more landslides.
From EARTH magazine, June 15, 2016 -- A 2002 eruption of Nyiragongo in the Democratic Republic of the Congo that killed more than 100 people also triggered an earthquake eight months later that shook the town of Kalehe in the Lake Kivu region. EARTH Magazine explores just what happened to better understand a region that is being pulled apart by plate tectonics.
May 28, 2016 -- IRIS does an excellent job collecting and preparing resources we can use in our classrooms on recent, significant earthquakes. Check out their PowerPoint, visualizations and animations on a magnitude 7.2 earthquake that occurred in the South Sandwich Islands, an uninhabited British territory off the coast of Argentina in the southern Atlantic Ocean.
From EARTH Magazine, 05/23/2016 -- When people think of dangerous faults in America, the the San Andreas probably comes to mind first. But another potentially greater threat lurks in the East Bay region of Northern California, just a stone's throw from San Francisco and the tech hub of Silicon Valley: the Hayward Fault. In the June issue, EARTH Magazine guest author Steven Newton lays out just what is at risk, and what to expect when an earthquake strikes on what may be the most dangerous fault in America.
