Happy #FieldworkFriday! We're showing off our red white and blue this week: Red Mountain (REDMT), White Pass (WPEQ), and Old Blue Mountain (OLBLUE). Have a safe and happy 4th of July weekend! 🇺🇸 🎆

On 7/8/25, the USGS & PNSN detected a swarm of earthquakes at Mount Rainier starting at 1:29AM PDT. Currently, there is no indication that the level of activity is cause for concern, alert level and color code for Mount Rainier remain at GREEN/NORMAL. volcanoes.usgs.gov/hans-public/no…

Director Harold Tobin with @SeattleTimes about the ongoing EQ swarm at Mt Rainier:  seattletimes.com/seattle-news/e… 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.

Happy #FieldWorkFriday! Two new seismic stations are now online: CRESC and CHUTE. UO College of Arts and Sciences students Karlee and Charlie installed the seismometers! The PNSN fosters undergrads' professional development by hiring summer field technicians at both our University of Oregon and @uofwa offices.

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

Happy #FieldworkFriday! Oh deer! The team ran into a handful of deer while installing new site ODEER on the Olympic Peninsula. It is extremely important to respect our wildlife and keep interactions to a minimum, but that doesn’t stop curious critters from checking us out!

Did you hear today's story about OHAZ on KLCC? KLCC joined the HBO seismic site upgrade last week! Learn from University of Oregon undergrads why they like working at OHAZ and how @pnsn1 seismic monitoring stations and USGS ShakeAlert improve resilience. klcc.org/disasters-acci…

Happy FieldworkFriday! We 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 line that the helicopter circles. Flying above Mt Rainier really puts into perspective just how big this volcano actually is!

Happy #FieldworkFriday! Station PRO, near Prosser, WA, was swept over by a brushfire this week! Thanks to smart vegetation management the site was totally spared from damage. It's a strong reminder of how proactive fire safety measures can prevent loss when the worst occurs.
