Earth and Space Sciences’ John Vidale, Paul Bodin, and the University of Washington-based Pacific Northwest Seismic Network team, will soon begin testing the region’s first early warning system for incoming earthquakes. Originally developed for use in California, the system will create an automated alert giving people anywhere from a few seconds to more than a minute’s warning before an earthquake’s S waves begin to shake the ground.

Earth and Space Sciences’ Frank Gonzalez, John Vidale, and Arthur Frankel, along with other scientists from across the University of Washington, are teaming up to better prepare our region for the next massive megaquake off the Pacific Northwest coast. Their efforts include designing the first tsunami evacuation structure in the United States, development of a campus-wide research project on major earthquakes, and the upcoming rollout of early earthquake alerts.

Snow is not as white as it looks. Mixed in with the reflective flakes are tiny, dark particles of pollution. University of Washington scientists recently published the first large-scale survey of impurities in North American snow, to see whether they might absorb enough sunlight to speed melt rates and influence climate. The results, published in the Journal of Geophysical Research, show that North American snow away from cities is similar to Arctic snow in many places, with more pollution in the U.S.

The Research Vessel Thomas G. Thompson —UW’s 274-foot-ship capable of accessing the world’s oceans—provided a platform for research and a home to several oceanography students as they wrapped up their quarter’s research in mid-December. Sending scientific instruments overboard to capture and record all sorts of ocean data, the students blogged about their adventures along the west coast of Canada and shared what they learned.

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water. Researchers found that water off the coast of Washington is gradually warming at a depth of 500 meters, about a third of a mile down.
