The Regional Seismic Network for Washington and Oregon. We operate almost 700 seismic stations and are the authoritative source for information about earthquakes in both states.
Happy #FieldworkFriday! The mountains around here are finally getting some snow! So when a critical relay station for Mt. St. Helens needed work, we had to bring out the big toys. It took a UTV with snow tracks (and a little bit of snow shoeing) to get to REDMT.

Happy #FieldworkFriday! Site DREAM is, well... exactly that, a dream. Stehekin although hard to get to, only accessible by ferry, is beautiful no matter the season. With less than a day to work we went into the dark of night & made a final check in the morning after a fresh snow.
A year ago, Washington got its first ShakeAlert warning for a M4.5 beneath Orcas Island. Thousands of people received an earthquake early warning alert—and over ten thousand reported feeling shaking! The alert system is working and ready for the next one: www.washington.edu/research-mak...
The 25th Anniversary Special on the Nisqually Earthquake aired this weekend on @KING5Seattle, featuring an interview with PNSN Director Harold Tobin. Revisit the 2001 quake and look ahead at how experts and community leaders are preparing for the next major quake.

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:

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...
“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...
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'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...
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...
Happy #FieldworkFriday! Some days our commute is a little more complicated than others.
4:30am - Leave Seattle
8:00am - Arrive at Mt St Helens staging area
8:30am - Helicopter leaves landing zone
8:40am - Helicopter lands at East Dome
8:45am - PNSN Field Crew begins maintenance on station EDM
Congratulations to the Seahawks on their NFC Championship! Check out this episode of The Sound of the Seahawks featuring a few short clips of PNSN at the stadium explaining the installs or monitoring process as well as highlights and recaps of both playoff games.

Happy FieldworkFriday! While visiting Browns Point Fire Department (BRPT) for maintenance this week we snapped this beautiful picture of Commencement Bay, Port of Tacoma, and Mt. Rainier.

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:
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...
SEAHAWKS ARE GOING TO SUPER BOWL LX!!!! Seattle Seahawks beat the LA Rams, 31 - 27!
Hopefully you got to follow along and catch each incredible play of this nail-biting game in real time, but if not then find the whole-game archive at: pnsn.org/data-researc...
Cooper Kupp completes a 13-yd TD pass from Sam Darnold! @Seahawks Touchdown!!
Steve Raible on the call, again.
Seattle is keeping the pressure against LA, with a 13-yd touchdown pass to Cooper Kupp!! The 12s aren't backing down either, keeping things loud as the score reaches 31-20.
AAAAAND THAT'S #3!!! The Hawks just can't be stopped! Jake Bobo scores with a 17 yard TD pass following a muffed punt by the Rams recovered by the Seahawks, and the score is now 24 - 13.
Are you watching our seismogram live? Don't forget to tune in to pnsn.org/seahawks!
ANOTHER TD FOR THE HAWKS!! Jaxon Smith-Njigba completes a 14 yrd pass, and the score is 17-13 while headed into halftime.
