To celebrate the launch, we are sharing a sneak-peek video that highlights the new front-page design. Thank you for being part of our community and for continuing to rely on the PNSN for trusted earthquake information.

The new site includes all the features you are familiar with, including real-time EQ info, event pages, station details, and research resources. And the most important under the hood improvements allow for better stability, faster loading, and a platform ready for future growth.

Chosen by Town & Country as one of the most anticipated books of the year, GAY LIKE ME by author Richie Jackson, is a cultural manifesto that will stand the test of time. To listen now, order your audiobook of GAY LIKE ME today!

We’re excited to share that the newly redesigned https://t.co/V9p7Uqr6K6 will officially go live on Thursday, December 11th. Our team has been working behind the scenes to modernize the site while keeping the tools and resources our community relies on.

Happy #FieldworkFriday! It can be challenging to work in the snow, and also a whole lot of fun! We left our mark in view of the White Pass Ski Area High Camp webcam this week after a trip to WPEQ. The lettering looks even better in night vision with Mt Rainier in the background.

Happy #FieldworkFriday and belated Thanksgiving! The PNSN would like to share our gratitude for our site hosts, partners, staff, and dedicated field team from UO, UW, and USGS. With cooperation we're able to maintain a reliable network of 700+ stations across the PNW.

PRELIM Earthquake: M3.5, 12.6 km S from Penticton, BC at 2025/11/27 23:19 PST https://t.co/GbkkVA7IfT Did You Feel It?: https://t.co/1iRgiljMQP

This alert is false. It was the waveforms from the M6.0 in Alaska. https://t.co/pKl7ilEoCh There was not earthquake in WA.

STAR is also the highest elevation seismic station in the contiguous US. (3365 m), about 300 meters above Camp Muir! For more information, check out our blog post:

Happy #FieldworkFriday! Mt. Rainier’s highest, most rugged station, STAR, made headlines this week after its signals were misinterpreted as unusual activity. In reality, the data reflect cold and icy conditions at 11,000' of elevation, not volcanic unrest.

Science time: Results have been obtained in definite contrast to the expectations of the neo-Darwinian theory.

There is no indication of increased seismic activity at Mt. Rainier in recent days. Other stations on the mountain are functioning normally and show normal background activity.

This older, low-power system is more susceptible to weather-related interference than our newer, higher-powered digital stations.

That station, STAR, is one of the last remaining old analog sites on the mountain and uses very low-power radio transmission to send data down to the receive site in Graham.

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.

Happy #FieldworkFriday! At OTR, on the Olympic Peninsula, our comms tower was wiggling when we climbed it, so we swapped all the bolts and really wrenched them down. This will ensure a stable tower and a safe worksite for years to come. It's the little details that matter!

Happy #FieldworkFriday! As we trudge through fall and approach winter the field team finds themselves fighting against the sunset. Add in the 1hr loss of light from Daylight Savings Time last weekend and we know we’re not the only folks working in the twilight hours.
