The Altiplano-Puna plateau is a high, dry region in the central Andes that includes parts of Argentina, Bolivia, and Chile, with vast plains punctuated by spectacular volcanoes. In a study published October 25 in Nature Communications, researchers used remote sensing data and topographic modeling techniques to reveal an enormous dome in the plateau.
About 1 kilometer (3,300 feet) high and hundreds of miles across, the dome sits right above the largest active magma body on Earth. The uplifting of the dome is the result of the thickening of the crust due to the injection of magma from below, according to Noah Finnegan, associate professor of Earth and planetary sciences at UC Santa Cruz and senior author of the paper.
"The dome is Earth's response to having this huge low-density magma chamber pumped into the crust," Finnegan said.

Emily Schwing is a journalist with a knack for mixing science and story-telling. She's most at home in the natural environment, getting to know people who are affected by things like climate change and resource development. She's also been known to track down scientists on things like ecosystem restoration, changing environments and human/environment interactions.
Her work in Alaska has garnered her the title of 'Mushing Correspondent.' She's covered the 1000 mile Yukon Quest International Sled Dog Race since 2010 and the 1000 mile Iditarod Trail Sled Dog Race since 2012. That's more than 9000 miles worth of tales from the trail!
Schwing also produces work for National Public Radio, the Canadian Broadcasting Corporation, Al Jazeera America, Public Radio International, Koahnic Broadcasting and National Native News and Mushing Magazine. She has contributed stories to American Public Media, Monitor Radio and Deutsche Welle.
Here she reports on the reconciliation process with Native American nations:

AMHERST, Mass. - Geomorphologists who study Earth's surface features and the processes that formed them have long been interested in how floods, in particular catastrophic outbursts that occur when a glacial lake ice dam bursts, for example, can change a planet's surface, not only on Earth but on Mars.
Now geoscience researchers Isaac Larsen at the University of Massachusetts Amherst and Michael Lamb at the California Institute of Technology have proposed and tested a new model of canyon-forming floods which suggests that deep canyons can be formed in bedrock by significantly less water than previously thought. They point out that "reconstructing the magnitude of the canyon-forming floods is essential for understanding how floods modify planetary surfaces, the hydrology of early Mars, and abrupt climate change."
Visitors to a world-famous fossil bed in Canada have discovered a handful of strange specimens that may likely turn out to be up to three new species of large ancient millipedes.
The find was made by chance last year in the Joggins Fossil Cliffs, which stretch several miles along the Bay of Fundy. The fossils are being analyzed now in labs in the United States and Canada. [...]
The fossils are an exciting find, says Alton C. Dooley, Jr., a National Geographic explorer who has studied ancient life and is the executive director of the Western Science Center in California. The specimens prove that there are still plenty of relatively large animals awaiting discovery.

I’m honored to nominate professor and GSA Fellow Alan Carroll of the University of Wisconsin–Madison for the Israel C. Russell Award. Alan Carroll’s exploration of Earth’s ancient lakes has resulted in fundamental advances in the study of lacustrine systems and terrestrial stratigraphy. His publications span four decades. Alan’s approach to sedimentary basins integrates detailed compositional and stratigraphic analysis, bed- to tectonic-scale problem solving, and a spirit of exploration. His deep-time paleolimnologic focus has inspired a generation of students to venture forth into the unknown in search of stratigraphic truths. Alan is well deserving of the honor.
Clínica Tepeyac today announced the appointment of Tillman Farley, M.D. as Interim Chief Health Officer.
Dr. Farley brings a range of experience working in clinics and hospitals, and has a deep understanding of the health challenges facing marginalized communities. He currently serves as the executive vice president for medical services of Salud Family Health Centers, a migrant/community health center with clinics across north and northeast Colorado. He also has a regular full-time appointment as associate professor in the department of family medicine in the University of Colorado School of Medicine.
Two CWU geology professors, Lisa Ely and Breanyn MacInnes, have received more than a quarter of a million dollars to study historic geological data in south-central Chile in order to better understand and assess the effects of powerful earthquakes and tsunamis, like those that occur in the Northwest.
Based on information gleaned in the field, MacInnes will develop computer simulations of tsunamis that could result from different megathrust fault ruptures to estimate the size and location of earthquakes in the last 2,000 years.
By working backwards from the evidence left in layers of sand and dirt, and in the tiny fossil shells of diatoms (a unique form of algae), investigators will try to deduce the origin and number of tsunamis in a particular area. They also hope to calculate the magnitude and characteristics of the ruptures and earthquakes.

I must have been five in the first storm I remember, walking home in Manhattan. I’d never seen rain like that, rain that soaked in an instant and made my favorite blue velvet slippers slide over the slick asphalt. Walk on the painted white line, my mother shouted above the roar of drops, it’s raised a little. And indeed it was enough of a difference to let me cross, one sodden slipper at a time.
A few things stick with me, attached to the image of blue slippers on a white line. A few inches of rain were enough to make it seem the sky was falling; a few millimeters enough to make a painted line into a bridge. Small differences, I learned, matter.
Once that thought was enough. It took root as I studied lakes in Tanzania, the summer after my sophomore year of college. I could always do this work, I imagined—research that sought to understand the environmental problems of the world. I thought eagerly of incremental change when a professor told me that science could profoundly alter the world, pull the rug out from under everyone’s feet. The idea guided me from a degree in geology to an application to do environmental work with the Peace Corps. My goals were modest: not saving the world, just doing a little good. Finding a little purpose. [..]
The reality was that paleoclimatology is a topic that makes eyes glaze over after the second syllable, one that people, sometimes including myself, consider academic in the dullest sense of the word. Worse yet could be using the phrase “climate scientist,” which risked derailing conversations and silencing formerly friendly checkout ladies. I found myself envying my doctor friends: how much more unassailable of a purpose can you have than healing others?
Interview with Dan Spencer:
Growing up in the West and working as a geologist, I have always been interested in environmental issues. In 1978, I went to Central America to work on a volcano, and found myself immersed in human rights issues instead. Throughout the 1980s, I worked on human rights and social justice issues in Central America and it was impossible not to notice how the poor were the most vulnerable to environmental degradation and “natural” disasters, from earthquakes to hurricanes to drought to pesticide exposure. Hurricane Mitch in 1998 left over 11,000 people dead in Nicaragua and Honduras, nearly all of them poor. It was as much a social as an environmental disaster, and it exposed the vulnerability of the poor to both social and environmental problems.
Two Yellowstone River oil spills have reshaped national pipeline safety laws signed Wednesday by President Barack Obama.
The PIPES Act sets pipeline law and reauthorizes the Pipeline and Hazardous Materials Safety Administration. The law addresses two of Montana’s worst oil spills: the July 1, 2011, Silvertip Pipeline spill into the Yellowstone River near Laurel and the Jan. 17, 2015, oil spill into the Yellowstone River upstream from Glendive. [...]
“There are some incremental improvements. There are clarifications, like the ice section and calling the Great Lakes a high-consequence area,” said Rebecca Craven, of Pipeline Safety Trust, government watchdog based in Puget Sound.
