UW oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring “Pythia’s Oasis.” Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

UW’s Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development; to offer virtual “dry run” experiences; and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.

Researchers at the University of Washington, Portland State University and the University of Oregon have shown that deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes. The open-access paper was published Sept. 16 in Science Advances. “Geomorphologists have long understood the importance of rainfall in triggering landslides, and our study is simply driving home just how important it is,” said first author Sean LaHusen, who did the work as part of…

Thousands of photos of glaciers, volcanoes, rivers and other natural phenomena are now easily viewed by the public through the University of Washington Libraries. UW Libraries’ Special Collections this fall released a new Glacier and Landforms Photograph Collection. The collection is designed to provide online access to photos of glaciers, geology and related subjects. At launch, the collection includes material from three photographers, and more will be added over time. Don Easterbrook, professor emeritus of geology at Bellingham’s Western Washington…

The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere. The results, published online May 9 in Nature Geoscience, reverse the commonly accepted idea that the early Earth had a thicker atmosphere to compensate for weaker sunlight. The finding also has implications for which gases…

The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. Since then it’s been revealed that this area has experienced major slides before, but it’s not known how long ago they occurred. University of Washington geologists analyzed woody debris buried in earlier slides and used radiocarbon dating to map the history of activity at the site. The findings, published online Dec. 22 in the journal Geology, show that a massive…

A new book by University of Washington geologist David Montgomery weaves history, science and personal challenges into an exploration of humanity’s tangled relationship with microbes, perhaps the least loved and most misunderstood creatures on Earth — and in you. “The Hidden Half of Nature: The Microbial Roots of Life and Health” comes out Nov. 16 from W.W. Norton & Co. Montgomery, a UW professor of Earth and space sciences, co-wrote the book with his wife, Anne Biklé, a biologist and…
