    50 simulations show how a 9.0 Cascadia earthquake could play out

    One of the worst nightmares for many Pacific Northwest residents is a huge earthquake along the offshore Cascadia Subduction Zone, which would unleash damaging and likely deadly shaking in coastal Washington, Oregon, British Columbia and northern California.

    The last time this happened was in 1700, before seismic instruments were around to record the event. So what will happen when it ruptures next is largely unknown.

    A University of Washington research project simulates 50 different ways that a magnitude-9.0 earthquake on the Cascadia subduction zone could unfold.

    “There had been just a handful of detailed simulations of a magnitude-9 Cascadia earthquake, and it was hard to know if they were showing the full range,” said Erin Wirth, who led the project as a UW postdoctoral researcher in Earth and space sciences. “With just a few simulations you didn’t know if you were seeing a best-case, a worst-case or an average scenario. This project has really allowed us to be more confident in saying that we’re seeing the full range of possibilities.”

    How will a 9.0 Cascadia earthquake affect Seattle?

    We know the "really big one" is coming. But what exactly is going to happen in cities along the coast? One University of Washington scientist created 50 simulations to show how strong the shaking will be. Here are two scenarios for Seattle — a "strong shaking" scenario and a "better case" scenario.

    Mountain glaciers shrinking across the West

    David Shean uses another technique, UW’s terrestrial laser scanner, to measure surface elevation at the South Cascade Glacier. Detailed measurements using this technique complement the satellite observations.

    Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each year since 1957 at South Cascade Glacier in Washington state; or tracking glacier area using photographs from airplanes and satellites.

    We now have a third, much more powerful tool. While he was a doctoral student in University of Washington’s Department of Earth and Space Sciences, David Shean devised new ways to use high-resolution satellite images to track elevation changes for massive ice sheets in Antarctica and Greenland.

    In 2012, he asked for satellite time to turn digital eyes on glaciers in the continental U.S., and has since collected enough data to analyze mass loss for Mount Rainier and almost all the glaciers in the lower 48 states. He will present results from these efforts Oct. 22 at the Geological Society of America’s annual meeting in Seattle.

    “I’m interested in the broad picture: What is the state of all of the glaciers, and how has that changed over the last 50 years? How has that changed over the last 10 years? And at this point, how are they changing every year?” said Shean, who is now a research associate with the UW’s Applied Physics Laboratory.

    Study points to win-win for spotted owls and forest management

    Remote sensing technology has detected what could be a win for both spotted owls and forestry management, according to a study led by the University of California, Davis, the USDA Forest Service Pacific Southwest Research Station and the University of Washington.

    For 25 years, many forests in the western United States have been managed to protect habitat for endangered and threatened spotted owls. A central tenet of that management has been to promote and retain more than 70 percent of the forest canopy cover. However, dense levels of canopy cover leave forests prone to wildfires and can lead to large tree mortality during droughts.

    In the study, published in the journal Forest Ecology and Management, scientists found that cover in tall trees is the key habitat requirement for spotted owl — not total canopy cover. It indicated that spotted owls largely avoid cover created by stands of shorter trees.

    Research on West Coast fisheries and human nutrition receives pilot grant from UW Population Health Initiative

    Can tapping into West Coast fisheries support human health and nutrition? With an inaugural pilot grant from UW’s Population Health Initiative, a multidisciplinary research team is studying how the fish we catch could support healthier diets for low-income communities. Dr. Edward Allison, School of Marine and Environmental Affairs, and PhD student Zach Koehn, School of Aquatic and Fisheries Sciences, are leading the work in partnership with Jen Otten, School of Public Health, and Ray Hilborn and Chris Anderson, also from the School of Aquatic and Fishery Sciences.

    Nutritious oily fishes, such as mackerel, herring and sardines, contain high levels of heart-healthy Omega-3 fatty acids that are unique to marine species. Right now, Allison explains, West Coast fisheries do not target most of these small “fishy flavored” species because of consumer taste preferences and economic incentives to catch a few popular species, like halibut and rockfish. When they are caught, these fish are sold for animal and aquaculture feed or discarded as bycatch. However, the West Coast is home to many peoples from traditional maritime cultures who would welcome the inexpensive fish into their diets.

    Allison’s team, comprised of fisheries, public health and policy scientists, sees an opportunity to connect low-income communities with these healthy, more affordable fish.

    “Good quality, nutritious food can be inexpensive,” Allison says. “Our work is part of a movement to democratize local food movements and make them more accessible to more people.”

    Allison hopes that his team’s research will: determine West Coast fisheries’ potential to support population health in local coastal communities; name current barriers that prevent nutritious, underused fish from reaching people who need them; and explore possible pathways to connect fisheries with communities — like having small community-supported fisheries deliver their bycatch to schools and meal programs. If the team identifies fishing policy and practice changes that could increase the supply of nutritious fish, those pathways could create new opportunities for organizations like SeaShare, a nonprofit that currently partners with fishermen to donate unsold fish to food banks.

    Managing fisheries for nutrition could also have positive environmental impacts.

    “Right now, we target a very specific number of species and thus take large chunks out of the ecosystem,” says Allison. “We have a huge diversity of fishes on the West Coast. There are a lot of edible things out there. It’s possible that by fishing for more species or more ages of fish overall, we could take smaller amounts of each kind from the ocean, which would have a less dramatic impact than removing, say, just the larger fish in the marine system.”

    The Population Health Initiative pilot research grant encourages new interdisciplinary collaborations among investigators for projects that address critical components of the grand challenges the UW seeks to address in population health. This year’s five awardees were selected by a panel of judges from a pool of 60 applications from faculty investigators representing the UW Bothell and UW Tacoma campuses as well as every school and college on the UW Seattle Campus.

    UW Environment is pleased to announce that Dan Brown will be joining the University of Washington as the new director of the School of Environmental and Forest Sciences, effective January 1, 2018. As director, Dan will play a vital role in guiding the School’s academic growth and developing new initiatives, providing leadership and management of its programs, centers, and research grants, allocating its revenues in a manner that supports its mission, and enhancing its sizable and growing endowment. In addition, the SEFS director also sits on the Natural Resources Board of Washington State, which oversees the management of state lands.

    “Dan is extremely well poised to take on this position. Throughout his career Dan has pursued research and teaching that cuts across the ecological and human dimensions of natural resources, and has engaged with the challenges inherent in multidisciplinary collaborations,” Lisa Graumlich, dean and Mary Laird Wood Professor at the College of the Environment said. “Through leadership positions, Dan has developed the skills necessary to identify and articulate how multiple disciplines and approaches can work together to address environmental questions and challenges.”

    Dan recently served as interim dean for the School of Natural Resources and Environment (renamed the School for Environment and Sustainability effective July 1, 2017) at the University of Michigan, where he is also a professor in the fields of conservation ecology and environmental informatics. His specific research interests focus on land use change and its effects on ecosystems and human vulnerability. His work connects a computer-based simulation of land-use-change processes with GIS and remote sensing based data on historical patterns of landscape change and social surveys. Join us in welcoming Dan to the School of Environmental and Forest Sciences, the College of the Environment and the University of Washington.

    The College also wishes to thank Liz Van Volkenburgh for her service as the interim director.

    “Liz has been a passionate advocate for the School and its community,” Graumlich said. “I am appreciative of her work to make the School, the College and the UW a more diverse, inclusive place, her commitment to learning as much as she could about the SEFS community so that she could better articulate its strengths and address its weaknesses, and her calm wisdom as she led the School through this transition.”
