Deepest scientific ocean drilling effort sheds light on Japan’s next ‘big one’
A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.

New UW Photonic Sensing Facility will use fiber-optic cables for seismic sensing, glaciology and more
A University of Washington pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, a nonprofit based in Vancouver, Washington, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.

New study calculates retreat of glacier edges in Alaska’s Kenai Fjords National Park
As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.

Farms following soil-friendly practices grow healthier food, study suggests
An experiment conducted on 10 farms across the U.S. suggests that crops from farms following soil-friendly practices for at least five years have a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Researchers believe soil microbes and fungi boost certain beneficial minerals, vitamins and phytochemicals in the crops.

Glaciers are squishy, holding slightly more ice than thought
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.

Simulations show how earthquake early warning might be improved for magnitude-9 earthquakes
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.

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere
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.

Edge of Pine Island Glacier’s ice shelf is ripping apart, causing key Antarctic glacier to gain speed
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.

Deep earthquakes within the Juan de Fuca plate produce few aftershocks
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.

Warming temperatures tripled Arctic lightning strikes over the past decade
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.
