PRELIM Earthquake: M3.8, 21.5 km NNE from Port Townsend, WA at 2026/07/01 23:35 PDT http://www.pnsn.org/event/714040221 Did You Feel It?: https://zpr.io/Ykx3uAUHQ9X5

An explanatory article from @evanbush.bsky.social at NBC News about the Venezuela earthquake(s). www.nbcnews.com/science/eart... ⚒️

NEW: Yesterday, a rare catastrophe struck Venezuela when a magnitude 7.2 and a magnitude 7.5 quake hit the same region *within less than a minute*. For the @nytimes.com, I asked scientists how this happened, why they were so devastating, and what might happen next. www.nytimes.com/2026/06/25/s...

So many newly-minted Geo-Doctors from University of Washington ESS Department for 2026! There are at least 2 more not in the pic. This is a really talented and fun bunch who are going on to great things. I’m going to miss them!! ⚒️

The NYTimes article about NSF dismantling the OOI system wasn't clear about what is actually happening. Yes, it's a really bad move for oceanography, but the part of OOI that monitors the Cascadia subduction zone is NOT being descoped. I went on KING5 News to discuss. youtu.be/NkTk60rxHVs?...

The 'bright spot' of ocean observatory cuts is earthquake monitoring remains in place

A massive rupture on the Seattle fault, which runs right under the Seattle metro area, could threaten millions and cause billions of dollars of damage. But it’s not just the biggest quakes scientists are concerned about. 🧪 eos.org/articles/on-...

On the Seattle Fault, the Biggest Quakes Aren’t the Most Likely - Eos

Smaller quakes from secondary faults—which are not included in national seismic hazard modeling—occur more frequently than previously thought.

Since around midnight PDT, there's been quite an active swarm of earthquakes at the Juan de Fuca Ridge, about 250 miles offshore WA. With 18 detected so far, up to M4.2, locations show that these are NOT at the Axial Seamount Volcano. They do not pose a hazard to the PNW onshore. ⚒️

Excellent article today in the NYTimes about the need for tsunami evacuation structures in the PNW.

Much of the West Coast and Hawaii faces some degree of tsunami risk. But if communities lack high ground to flee to before the waves hit, they really have one option: build up. Tsunami shelters are ubiquitous in tsunami-prone Japan, but the US has only a handful. 🎁🔗 www.nytimes.com/2026/04/11/r...

Finally a convincing explanation for the existence of blueschist and eclogite belts. ⚒️

Magnitude 6.3 thrust earthquake in the Atacama area of central Chile this morning. This is in the area of a 1922 M8.4. Most subduction quakes are not foreshocks, but chances of a larger event in the short term are now a bit higher, statistically speaking. 👀 ⚒️ earthquake.usgs.gov/earthquakes/...

15 years ago right about this time of day, the Tohoku-oki earthquake was unleashed, with as much as 100 meters of fault slip documented at the Japan Trench. The resulting tsunami rocked Japan and the world, claiming ~18,000 lives. It was one of only 5 M9 quakes ever recorded. ⚒️

Ok, journals don't really appear as bound paper magazines anymore, but it's still pretty cool to get the cover image! Anna Ledeczi's paper on our newly identified paleo-megathrust in the heart of Olympic National Park is now formally out. Read it here: ⚒️ pubs.geoscienceworld.org/gsa/gsabulle...

Did you know that the Feb. 28, 2001 Nisqually earthquake was the costliest quake in the past 30 years of US history? On its 25th anniversary, the Puget Sound region isn't prepared for the inevitable next one. Here's my take for the @seattletimes-rss.bsky.social www.seattletimes.com/opinion/befo...

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.

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...

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...

We're ready for you, 12s! The PNSN's field staff revisited Lumen Field this week to ensure our stations were functioning correctly so we can monitor all of the fan generated energy from today's Seahawks game vs the Rams. Make sure to follow our live seismogram during the game at seahawks.pnsn.org!

Rashid Shaheed got things started right away with an opening kickoff return touchdown, the 12s rocked the house, and the Seahawks never looked back! SEAHAWKS WIN 41-6 and move onto the NFC Championship Game! @seahawks @nfl

Follow along with ground motions at Lumen Field as the Pacific NW Seismic Network @pnsn1.bsky.social livestreams our seismometers in and next to Lumen Field! Seahawks up 17-6 late in 2nd qtr. Stream: seahawks.pnsn.org

TOUCHDOWN SEAHAWKS! Rashid Shaheed returns the opening kickoff for a touchdown! Great start, 12s! @seahawks @nfl @nflonfox

It looks like northern Japan coastal ports have seen tsunami waves arriving already, but so far just 30-70 cm high. Later-arriving peaks could be higher, but that is good news that the ultimate size will be moderate. I hope so! Damage reports sketchy so far, but also some reason for optimism.

I love this. @pnsn1.bsky.social

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.

NOAA cut funding for critical parts of the tsunami and earthquake detection system in Alaska, primarily in the Aleutians. I spoke to Wash Post about negative impacts. But, hey, what are the chances of a deadly tsunami being triggered in Alaska? (Gift article, not behind paywall) ⚒️ wapo.st/4qKvavQ

This lab is key for tracking deadly waves. Its sensors are about to go offline.

After NOAA cut funding to the lab that’s been monitoring seismic activity for more than 25 years, nine stations tracking tsunami-causing earthquakes for the agency will go offline by the end of the mo...

This visualization of Japan’s M6.8 yesterday is phenomenal. Offshore S-net detected it and issued earthquake alert before any land station detection. Numbered circles show JMA intensity (not same as MMI). Offshore is where we need to be in Cascadia as well.

The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku. Reposting unofficial visualization by x.com/kotoho76/sta...

Today's Japan M6.8 is in an interesting spot: the zone of "missing" slip just north of the very large shallow rupture in the 2011 M9.

⚒️ 🧪 A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude. What do we know? What might happen next?

Quoted supporting our counterparts and friends at the Alaska Earthquake Center. The cost of the U.S. tsunami warning and mitigation effort is really a pittance. None of it has ever been adequately funded in any administration, and now things are worse. ⚒️ www.nbcnews.com/science/tsun...

U.S. tsunami warning system, reeling from funding and staffing cuts, is dealt another blow

Seismic monitoring stations in Alaska are closing after a denied federal grant, risking delayed tsunami warnings for people living on the West Coast.
