UW Magazine featured the installation of a new @pnsn1.bsky.social seismic station last August at Burley Mountain. It joined more than 700 other stations spanning WA and OR to monitor shaking from earthquakes and volcanic eruptions for the #ShakeAlert early warning system. https://bit.ly/4pidxlh

@agu.org honored five @uofwa.bsky.social faculty and researchers from the @uwess.bsky.social and atmospheric and climate science departments this week at the annual meeting in New Orleans.

For #FieldworkFriday, we want to extend our thoughts to those in Stehekin and throughout Washington who have been impacted by recent flooding. During our installation of DREAM this summer we met so many friendly, welcoming & helpful people in that unique and resilient community.

We are thrilled to celebrate five #UWEnvironment researchers who received awards from @agu.org this year! Clockwise from top left: Michelle Muth, Joshua Krissansen-Totton, Fang-Zhen Teng, Christopher Kenseth and Dale Durran. https://bit.ly/4j7Ilna @uwess.bsky.social @uwnews.uw.edu#UWEnvironment#AGU25

At @uwess.bsky.social, the David A. Johnston Memorial Fellowship Endowment supports grad students in geology and geophysics, honoring the late USGS volcanologist and alum. Friends of Earthquakes backs seismic research and monitoring networks like @pnsn1.bsky.social—crucial back in 1980 and today.

Researchers are testing a way to monitor marine mammals on a large scale, using an existing global network of previously dormant telecommunications cables: https://bit.ly/4oh16p6

Panic is temporary...existential dread is forever

Some false reports are circulating that Mt. Rainier is suddenly showing seismic tremor activity — this is not true. The signal being referenced is actually radio interference, most likely due to rime ice buildup on the antenna of one of our seismic stations.

ESS alumna and Indiana University Bloomington Assistant Prof. Dr. Julia Kelson was awarded the Geological Society of America's prestigious Donath Medal (Young Scientist Award) for pioneering Earth science research. Kelson got her PhD from ESS in 2019, advised by Prof. Kate Huntington.

Still waiting for someone to get me some tsunami awareness jewelry 👀 I guess I will just keep scrolling dnr.wa.gov/tsunamis while I wait

💡UW Bothell researchers are repurposing fiber-optic cables to monitor orcas in Puget Sound. Led by Shima Abadi, with ESS co-PIs Drs. Brad Lipovsky and Marine Denolle, this work could transform global cable networks into tools for marine conservation. 🐋 www.uwb.edu/news/2025/10...

Over 600 years ago, a massive earthquake and tsunami struck the northeastern Caribbean. Flooding scattered coral boulder across the island. The corals died but their skeletons remain. Scientists are learning that these skeletons hold clues about tsunami history. www.washington.edu/news/2025/10...

If you're in #Seattle on Friday and want to get on board a historic tall ship, come visit us at Pier 66! We'll be aboard the Statsraad Lehmkuhl during One Ocean Week Seattle. Come see the boat, learn about ocean science, and say hi to us from #UWEnvironment! Register: https://bit.ly/4o3TKpS

It's time! Where ever you are DROP, COVER, and HOLD ON. Take part with people all over the world in the Great ShakeOut and practice your earthquake safety!

Did you DROP, COVER, and HOLD ON yet today? If not, don't worry - it's never too late to practice earthquake safety! Try doing your own drill at your home, office, or school and take part in the #GreatShakeOut alongside millions of others.

PNSN is back at the ball park for game four of the ALCS! Root for the @mariners and watch our live seismogram streaming from T-Mobile Park. Here: mariners.pnsn.org #SeizeTheMoment

A new study proposes that a tsunami struck the Caribbean island of Anegada between 1381 and 1391, carrying huge coral boulders inland and leaving behind a valuable record of geologic and climatic history. https://bit.ly/4nUN90N @uwess.bsky.social @uwnews.uw.edu

Recent @Mariners games have been shaking things up enough for our seismometers to notice but those waves are all in good fun. It's a great reminder that real quakes can happen anytime. Join us tomorrow (10/16) for @ShakeOut and practice what to do when the ground really moves.

Analysis of data from the Cassini space probe has identified organic compounds within jets of water ice erupting from Saturn’s moon Enceladus. Some of the compounds have never before been identified on another world beyond Earth. More: www.washington.edu/news/2025/10...

New Cassini data reveal organic compounds, some never before identified on a world beyond Earth, in jets of water ice from Saturn’s moon Enceladus — findings by UW postdoc Fabian Klenner and colleagues strengthen the case that Enceladus could support life. 🔬🪐 @uwenvironment.bsky.social

A tiny site in rural Pierce County is one of ~650 seismic stations operated by @pnsn1.bsky.social to detect and monitor #earthquakes in the #pnw. It was key to detecting a swarm of small earthquakes at @altmtrainier.com#earthquakes#pnwast summer. https://bit.ly/3IQrckf

Ocean oxygenation was a gradual process. Shallow areas near the shore were oxygenated first, and inhabited by breathing species. As oxygen permeated deeper and deeper, ocean-dwellers followed, leading to a rapid expansion of jawed vertebrates. @uwess.bsky.social

For years, researchers have hypothesized that westerly winds were ferrying warm water toward the West Antarctic Ice Sheet, accelerating ice melt. A new @uwess.bsky.social study flips the existing narrative on its head, pointing toward winds from the north instead. www.washington.edu/news/2025/09...

ESS Assoc. Professor Marine Denolle and PhD student Yiyu Ni are featured in this first episode!

🐟 ESS PhD student Kunmanee Bubphamanee co-authored new research showing the deep ocean only became oxygenated about 390M years ago due to the spread of land plants. This shift made the deep sea habitable to animals like early jawed fish, the ancestor to modern vertebrates. Read the full story 👇

@uwenvironment.bsky.social will expand its work related to climate solutions thanks to a grant announced today from Fund for Science and Technology, a new foundation within the Paul G. Allen philanthropic ecosystem.

@uwess.bsky.social Assistant Research Professor TJ Fudge talks about the status of glaciers in the Pacific Northwest and the dangers of shrinking glaciers. www.king5.com/video/tech/s... #UWEnvironment

“Our whole Earth system depends, in part, on these ice sheets,” said Dominik Gräff. “It’s a fragile system, and if you disturb it even just a little bit, it could collapse. We need to understand the turning points. This requires deep, process-based knowledge of glacial mass loss."

Great job opportunity with the California Geological Survey. @uwess.bsky.social @pnsn1.bsky.social

On clear days, when Mt. Rainier is visible from Seattle and Tacoma, locals say "The mountain is out." But lately, melting #glaciers have made that iconic view look rockier and less snowy, @knkx.org reports. https://bit.ly/4mSxCxF @uwess.bsky.social#glaciers

UW ESS scientists deployed a fiber-optic cable across a Greenland fjord to capture how calving ice triggers hidden waves that pull warm water up, speeding melting. This key process accelerating glacial mass loss threatens ice sheet stability, ocean currents, and ecosystems. #UWESS #UWEnvironment

Happy FieldworkFriday! We strapped a GoPro to the skids of a helicopter for a recon flyover of St. Andrews Rock (STAR). The station is hard to spot on the ridge that the helicopter circles. Flying above Mt Rainier really puts into perspective how big this volcano actually is! youtu.be/PJ242pHcBGU

Director Harold Tobin with @SeattleTimes about the ongoing EQ swarm at Mt Rainier:  www.seattletimes.com/seattle-news... It’s the biggest swarm since 2009, we’re closely monitoring the EQ activity, but we don’t see anything to elevate the level of concern about volcanic activity at this time.

Position opening at the Pacific Northwest Seismic Network. For more information and to apply please visit bit.ly/4lHmP8M

The mountain is out! ⛰️ @uwess.bsky.social researchers went to Mt. Rainier last weekend to place 240 small seismometers around the park. The seismometers will capture tiny ground vibrations such as earthquakes & glacier quakes with the goal of better understanding surface hazards like avalanches.

Deadline for the GeoFutures program has been extended to 07-11-25. The program provides travel & mentoring support for geoscience undergrads attending the 2025 SACNAS conference. @accessiblegeo.bsky.social @agu.org @official-bweems.bsky.social @sacnas.bsky.social environment.uw.edu/about/inclus...
