Though usually though of as a solid, glaciers are also slightly compressible, or squishy. This compression over the huge expanse of an ice sheet — like Antarctica or Greenland — makes the overall ice sheet more dense and lowers the surface by tens of feet compared to what would otherwise be expected.
Seismologists used 30 detailed simulations of magnitude-9 slips on the Cascadia Subduction Zone to evaluate how the ShakeAlert earthquake early warning system would perform in these events. Results show the alerts generally work well, but suggest that lower alert thresholds provide more timely warnings over the full area that will feel the shaking.

The new Cascadia Coastlines and Peoples Hazards Research Hub, led by Oregon State University and the University of Washington, will study coastal hazards and community resilience. The National Science Foundation awarded $18.9 million for the hub over five years.
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.
This week, a few members of our UW News team joined glaciologists from the UW Department of Earth & Space Sciences on a trip to Mt. Baker. Students that came along got to chat with their professor on the hike up, and we learned about how the recent heat wave impacted the snow melt on the ice.
Satellite images show that from 2017 to 2020, Pine Island Glacier’s ice shelf lost about one-fifth of its area, mostly in three dramatic breaks. This caused the glacier to speed up by 12%, hastening its downward motion and boosting its contribution to rising seas.
University of Washington glaciologists are co-authors on two papers that analyzed Antarctic ice cores to understand the continent’s air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition.
The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network, and state emergency managers on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state. This completes the rollout of ShakeAlert, an automated system that gives people living in Washington, Oregon and California advance warning of incoming earthquakes.
Leveraging the tectonic laboratory of the Cascadia subduction zone, the University of Washington today announced a new effort to best understand how to study and live with the threats of earthquakes, tsunamis, volcanos, landslides and other seismic hazards. Dubbed the GeoHazards Initiative, the interdisciplinary work aims to develop and promote the adoption of early detection systems both on land and at sea to help prevent the loss of human life and property.
In the Cascadia subduction zone, medium- and large-sized “intraslab” earthquakes, in which the slip happens within the oceanic plate and below the continental plate, will likely produce only a few detectable aftershocks, according to a new study from the University of Washington and the U.S. Geological Survey.
Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes.
After years in development, an earthquake early warning system known as ShakeAlert is on the cusp of being released in Oregon and Washington. Harold Tobin, director of the Pacific Northwest Seismic Network, answers questions about the coming rollout.
Human-caused warming is responsible for increasing the risk of a glacial outburst flood from Peru’s Lake Palcacocha, threatening the city below. This study is the first to directly link climate change with the risk of flooding from glacial lakes, which are growing in number and size worldwide.
Antarctica’s next deep ice core, a 1.5-mile core reaching back to 130,000-year-old ice, will be carried out by a multi-institutional U.S. team led by UW’s Eric Steig. The site hundreds of miles from today’s coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.

A new study combines ice cores, geologic records and computer models to understand the past, present and future of the Greenland Ice Sheet. The results show that emissions this century have a big influence on how much ice will be lost from Greenland.
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…
Seven scientists and engineers at the University of Washington have been elected to the Washington State Academy of Sciences, according to an announcement July 15 by the academy.
Evidence from rocks billions of years old suggest that volcanoes played a key role in the rise of oxygen in the atmosphere of the early Earth.
