Happy #FieldworkFriday! We retrieved our trail cam from Emerald Ridge (RER) last week which took daily photos from September 2023 to January 2025. This insight shows that our extended solar panel plays a vital role, at times being the only thing above the deep snow.

PNSN’s stations monitor seismic activity in our region, but they also capture signals from earthquakes all around the world. Seismic waves from today’s M6.8 earthquake in Kumamoto, Japan traveled over 5000 miles to our network in WA and OR, arriving just over ten minutes later.

⚒️ 🧪 A M6.8 earthquake struck Kyushu, Japan today. Large quakes in Japan are common and often pass without much notice, but this one is serious - instead of occurring offshore in the subduction zone, it is a shallow, strike-slip event near Kumamoto. Damage and deaths have already been reported.

We’re here in Cal Anderson Park sharing information about earthquake hazards and ShakeAlert earthquake early warning at the 2026 Seattle Disaster Relief Trials, a cargo bike competition and exercise showing how micromobility can contribute to community disaster response.

Happy #FieldworkFriday! Love hiking? Come along with us as we trek to RER, a seismic station at Emerald Ridge on Mount Rainier, and see where fieldwork takes us.

With 569 seismic monitoring stations across WA and OR, the ShakeAlert earthquake warning system installations are now complete! Researchers at @pnsn1.bsky.social are exploring how to expand the system to better detect offshore earthquakes. https://bit.ly/4wNMbre 📷: University of Washington

Our Newest cryptid has really been shaking things up here in Washington. ...What can Jimothy teach us about #earthquake safety?

PNSN Director Harold Tobin spoke to KOMO about the M7.3 earthquake that struck off the Pacific Coast of Mexico today—and what it means for the Pacific Northwest. Watch here: www.youtube.com/watch?v=_Rsp...

Tsunami? The impacts of the string of powerful earthquakes that struck near Mexico and Guatemala

A powerful 7.3 magnitude earthquake struck off Mexico's southern Pacific coast Friday near the Guatemala border, shaking communities across southern Mexico and Central America while prompting tsunami…

Happy #FieldworkFriday! PNSN field crew recently took a helicopter ride to upgrade equipment at seismic station OSD (Snow Dome) on Mount Olympus in Olympic National Park. Ride along to check out the views!

Presentation recordings, slide decks and other resources from CRESCENT's recent Partnerships & Applications Workshop are now available at: https://ow.ly/tvxs50ZoZvh

A M7.3 earthquake struck offshore near the border of Mexico and Guatemala. Offshore southern Mexico and Central America, the Cocos Plate subducts beneath the North American and Caribbean plates, resulting in frequent large earthquakes. Learn more & access event data ➡️ https://loom.ly/qBQlsMY

PNSN staff & our USGS Seattle colleagues are in Portland for the second time in a month! We came in June for a @cascadiaeqs.bsky.social workshop on earthquake/tsunami scenarios; now we're at the 13th National Conference on Earthquake Engineering connecting earthquake science & engineering practice.

We are excited to announce the publication of two foundational articles on CRESCENT in Seismological Research Letters! https://cascadiaquakes.org/2026/07/10/crescent-srl-papers/

Happy #FieldworkFriday! After wrapping up work at station BOW2, our field team spottted two young fawns nearby. Were they curious future field assistants, or just taking a quick break from playing tag with each other?

7 seismometers, 6 soccer matches, and 21 goals! Here's how the seismograms for every World Cup goal scored at Seattle Stadium stack up. Read the Seattle Times story for more about PNSN's sports seismology (and the real earthquake kind): www.seattletimes.com/seattle-news...

UW student journalists at The Daily covered PNSN's experiments with World Cup seismology as tool for public outreach and science education—read the article here: www.dailyuw.com/article/seis...

And with a final goal from Romelu Lukaku at 90+3, it ends in a 4-1 victory for Belgium. That's it for the #2026WorldCup at Seattle Stadium, but keep an eye out for a roundup of all the goals we captured during the six matches hosted here—and stay tuned for more #SportsSeismology experiments to come!

Oooof: Hans Vanaken scores for Belgium, and now it's 3-1. The Belgian fans at Seattle Stadium aren't shaking the building as hard, but they're getting more opportunities to record their goal reactions at station HWK3.

And then de Ketelaere scored for Belgium again just two minutes later. This is the response from the Belgian fans at station HWK3. #SportsSeismology #WorldCup2026 #FIFAWorldCup

Malik Tillman's free kick equalizes for the USA at 31 minutes! The fans made Seattle Stadium shake and we captured this seismogram of their reaction at station HWK3. #SportsSeismology #WorldCup2026 #FIFAWorldCup

Belgium scores first! Goal by Charles de Ketelaere nine minutes into the match—here's the reaction from the Belgian fans recorded by our station HWK3. #SportsSeismology #WorldCup2026 #FIFAWorldCup

Doing a vibe check and making sure everything is ready for the USA vs Belgium match at Seattle Stadium. Vibes are immaculate and everything is ready to rock! Check out all the action on pnsn.org here: buff.ly/BEJqFSa #SportsSeismology #WorldCup2026

Fox Q13 caught up with us while we were doing our stomp test down at station KDK by the Seattle Stadium this morning. Watch the clip here: www.fox13seattle.com/video/fmc-8p... and join us online at pnsn.org at 5 PM PDT for the USA v Belgium match!

Seismic stomp test at Seattle Stadium

The Pacific Northwest Seismic Network is measuring fan energy in and around Seattle Stadium using its Seismic Stomp Tests.

The PNSN team is down here at "Seattle Stadium" to do a live stomp test at seismic station KDK as we prepare for tonight's USA-BEL match! Stop by to join in and get stickers if you're in the area. Find us in Hot Dog Alley (Occidental Ave S) for the next hour or so! #WorldCup2026

Curious about how the soccer fanquakes we’ve been recording at Seattle World Cup matches differ from an actual earthquake? Compare these seismograms from the Freeman goal and the M3.8 earthquake near Oak Harbor last week.

Wondering about that M3.8 earthquake near Oak Harbor last night? PNSN Director and Washington State Seismologist @haroldtobin.bsky.social explains what we recorded and how PNSN is monitoring the seismic activity.

Our seismometers didn't just record soccer fanquakes yesterday—we also had a M3.8 earthquake near Oak Harbor! Here's how that earthquake was recorded by six PNSN seismic stations nearby and a ShakeMap showing the intensity of the shaking.

If you felt that earthquake, please fill out the short DYFI? form linked in our automated post below! Thank you for contributing to citizen science. 🫡
