Tidal tugs on Teflon faults drive slow-slipping earthquakes

Unknown to most people, the Pacific Northwest experiences a magnitude-6.6 earthquake about once a year. The reason nobody notices is that the movement happens slowly and deep underground, in a part of the fault whose behavior, known as slow-slip, was only recently discovered. A University of Washington seismologist who studies slow-slip quakes has looked at how they respond to tidal forces from celestial bodies and used the result to make a first direct calculation of friction deep on the fault.

A year later, UW geologist reflects on Oso and the need for better application of landslide science

View of Oso landslide from the air

Earth and Space Sciences’ David Montgomery is one of many University of Washington researchers who have been working to develop and analyze critical data in the aftermath of last year’s landslide in Oso. March 22, 2015 marked one year since the largest recorded landslide in U.S. history decimated a western Washington community and killed 43 people. In the wake of that disaster, Montgomery has some thoughts about how to make landslides less deadly.

UW scientist leads multinational study on the future of Arctic marine mammals

Aquatic and Fishery Sciences’ Kristin Laidre and a team from across the globe just published their findings on what the future looks like for Arctic marine mammals, whose fragile habitats are shifting as a result of sea ice loss and warming temperatures. Their recent study, published in Conservation Biology, found that reductions in sea ice cover are “profound” and that the Arctic’s traditionally short, cool summers are growing longer in most regions by five to 10 weeks.

Kill two birds with one dead tree? Beetle-killed pines could fuel machines instead of fires

beetle-killed forest in CO

Across western North America you can see them: hills blanketed with swaths of red and gray trees. These dead and dying stands of pine, aspen, and fir, totaling around 42 million acres—roughly the size of the state of Washington—are victims of bark beetles. And the dry, decaying trees that the beetles leave in their wake are not just eyesores; they also fuel hotter and larger wildfires.

UW's Friday Harbor Labs prove to be a prime spot to study ocean acidification

For more than a century, scientists at UW have utilized Friday Harbor Laboratories’ unique location on the shores of the Puget Sound to study a variety of marine species. With the debut of the Ocean Acidification Environmental Laboratory in 2011, research at Friday Harbor Labs expanded into monitoring the water’s pH and dissolved oxygen levels, total alkalinity, effects of ocean acidification, and strategies for adaptation.
