Experts discuss 25th anniversary of WA's Nisqually quake We're three days away from the 25th anniversary of the Nisqually Earthquake.

25 years ago this weekend, western Washington was shaken up by the Nisqually earthquake. Experts from PNSN and UW explain what we’ve learned since—and what we need to do to get ready for the next one:

25 years after Nisqually quake, expert warns 'it will happen again' The City of Seattle marked the anniversary of the 6.8 magnitude earthquake on Thursday by discussing ongoing contingency plans for another powerful quake.

Today is Nisqually Earthquake Awareness Day! “Prepare, don’t despair”—that’s our message on the 25th anniversary of the 2001 M6.8 earthquake. Learn more in this clip: www.king5.com/article/news...

Before the next earthquake hits WA, we need to fix our bricks | Op-Ed An earthquake like the 2001 Nisqually quake will strike again, and it could be more damaging. What is certain is that we can make structures safer.

“If Washington has the will, we certainly have the means to make our state safer and better before the next time an earthquake strikes.” Read this op-ed from PNSN director @haroldtobin@bsky.social in today’s Seattle Times about how we can #FixtheBricks: www.seattletimes.com/opinion/befo...

Happy throwback #FieldworkFriday! Fieldwork isn't just maintaining our stations - sometimes we must record the effects that earthquakes have on landscapes and built environments.

Here are some images collected by PNSN and fellow researchers after the Nisqually EQ 25 years ago.

25 years ago this week, the Nisqually earthquake shook up the Pacific Northwest—including the UW Engineering Library! Join us tomorrow evening for a panel and Q&A with earthquake experts about what we’ve learned since 2001, and how to prepare for the next big one: www.eventbrite.com/e/25-years-s...

PNSN will be participating in the Pacific Science Center’s Engineering Day tomorrow afternoon—come check out our interactive Make-A-Quake seismometer demo, real seismic instruments, and live earthquake displays showing ground motion as it happens! pacificsciencecenter.org/events/engin...

25 years ago, PNSN seismologists rolled into action to respond to the M6.8 Nisqually earthquake. Join us on Feb 24, 6:30-8 PM for a discussion and Q&A with earthquake experts on what we’ve learned since—and what we need to do to get ready for the next one: www.eventbrite.com/e/25-years-s...

A green pasture is filled with a flock of white geese, with many more flying overhead.

A plump green frog sits on a metal ledge inside of the station's enclosure.

A deer stands in a pasture, looking towards the camera.

The station sits in a meadow, with its solar panels resting on a metal frame and facing towards the sun, which hangs in a slightly cloudy sky.

Happy #FieldworkFriday! Frogs, deer, and geese, oh my! PNSN field staff found many animals this week at site HILL, where they replaced the solar charge controller. The frogs at the station are still seismologists-in-training, but we're "hopping" they can help next week, too!

It takes place at the Kelly Ethnic Cultural Theater, at 3930 Brooklyn Ave NE in Seattle, on Feb 24th at 6:30pm. Admission is free. There is a QR code on the right side linking to a registration page.

It's been 25 years since the Nisqually earthquake—are we ready for the next one? Join us at UW next week (Tuesday, Feb 24) for a conversation and Q&A with local experts about earthquake science, policy, & preparedness in the PNW. Register here to attend: www.eventbrite.com/e/25-years-s...

Seismic site GORGE sits on a grassy hill overlooking the Columbia River valley. It is a slightly cloudy, sunny day.

Happy #FieldworkFriday! Our station GORGE is now powered up! After upgrading from 2 to 4 solar panels, & adding a wind generator, we had to adjust for all the extra power. The recent “false-spring” weather here in the PNW has this station looking GORGEous & getting lots of juice!

What Steve Raible called "the loudest, most dedicated, most feared fans" in the NFL packed Lumen Field & Seattle streets this morning for the Seahawks ceremony and #SuperBowl victory parade! Check out the noise at seismic station KDK compared to an average morning nine days ago!

Like Marshawn Lynch, we're with you, Seattle! NFL on Prime shared this clip of Beast Mode's visit to PNSN to commemorate the #Beastquake—check out the video to reminisce with us: www.facebook.com/nflonprime/v...

The seven largest seismograms from plays during the NFC Championship game between the Seattle Seahawks and the LA Rams.

The 12s shook the stadium during yesterday's NFC Championship game between the Seattle Seahawks and the LA Rams, but which plays created the most seismic activity? Here are how the top 7 seismic moments from last night's game compare to each other:

Retrofitting buildings in preparation for our region’s next big earthquake will save lives! 🧱 Retrofitting URMs is not just about preparing for the next earthquake; it's also about supporting… Fix The Bricks! Building Safety is Earthquake Safety

Today marks the anniversary of the 1700 Magnitude 9 Cascadia Subduction Zone earthquake, reminding us to be prepared for strong shaking in the PNW. URMs are particularly vulnerable, but retrofitting can mitigate the risk. #FixTheBricks www.youtube.com/watch?v=C5wa...
