Pacific Northwest Seismic Network@pnsn1.bsky.social · 2mo ago“And the building shakes in Seattle!” PNSN’s seismic stations captured the crowd response to both Alex Freeman’s goal and the VAR decision overturning the offside call. It’s #USMNT 2 to Australia 0 at half-time. #WorldCup2026 #FIFAWorldCup #SportsSeismology

MBARI@mbarinews.bsky.social · 7mo agoNew research led by @chillocean.bsky.social and the USGS Pacific Coastal and Marine Science Center used MBARI’s technology to map the distribution of deposits left on the seafloor after an earthquake, revealing the seismic history of the Pacific Northwest.

ICYMI: Our #USGS #scicomm put together a great video about our research into #earthquake records in the Cascadia subduction zone. 🧪⚒️🌊 You can read our new paper in Science Advances here: www.science.org/doi/10.1126/...
Our new paper on earthquake records in the Cascadia Subduction Zone is out today! The goal of our work is to reduce uncertainty in the timing and frequency of large earthquakes by investigating how and where subduction earthquake-triggered deposits are formed. 🧪⚒️🌊 www.science.org/doi/10.1126/...
Widespread abyssal turbidites record megathrust earthquake-triggered landslides and coseismic deformation in the Cascadia subduction zone
Lower slope failures produce abyssal turbidites that record shaking and coseismic deformation during megathrust earthquakes.

New seafloor mapping offshore Alaska in the Alaska-Aleutian subduction zone! #USGS #NOAA #MarineGeohazards 🧪⚒️🌊
New seafloor mapping offshore Kodiak Island, Alaska, reveals extensive submarine landslides
In summer 2025, a research team led by the USGS worked with the NOAA ship Rainier to map a large swath of seafloor offshore of Kodiak Island, Alaska, along the Alaska-Aleutian Trench.

the California Geological Survey has prepared a survey to gather your observations from the M8.8 Kamchatka, Russia Tsunami If you have been able to make any observations of the tsunami or of the evidence left behind by tsunami, we want your information: survey123.arcgis.com/share/76979d...
An important reminder from the US National Weather service regarding the US west coast tsunami advisories following today’s M8.8 Kamchatka quake:
The Ecosystems Mission area is a major component of the USGS Alaska Science Center, along with Earthquake, Landslide and Volcano Hazards, Energy & Minerals - these folks are hard working scientists who do great work. 🧪⚒️
Kevin Berry 🇺🇦@kevinberryecon.bsky.social · last yr.The Ecosystems Office at USGS Alaska does important work for responsible resource development in Alaska & more people should know about their role in supporting our economy. Their mission is worthy of continued federal funding www.usgs.gov/centers/alas...
The USGS is the only non-regulatory federal agency with a mission to conduct science in the public interest. The President’s FY26 budget aims to zero out the Ecosystems Mission Area. The quote from the NPR story below shocked me. See what they do: geonarrative.usgs.gov/ecosystemsmi... 🧪⚒️

Another curious specimen from marine sediment cores - anyone have thoughts on what these copper brown coils might be? Could be terrestrial (from ice age) or marine. 👽, 🐌, 💩 have all been suggested… This sample is from the Bering Shelf in about 40m of water. 🧪⚒️🌊
Check out this nice study about the cascading hazards in the Cascadia subduction zone 🧪⚒️🌊
Tina Dura@diatomdura.bsky.social · last yr.🚨New Study Alert!🚨 Our new PNAS study shows how earthquake-driven land subsidence + rising seas = major flood hazards along the Cascadia subduction zone. 🌊🌎 @cascadiaeqs.bsky.social (1/🧵) www.pnas.org/doi/epdf/10....

I just heard some excellent news regarding one of these datasets - the IMLGS (Index to Marine & Lacustrine Geologic Samples) - SESAR2 (www.geosamples.org) has agreed to host it going forward! 🧪⚒️🌊 This is a super valuable dataset - thanks so much to these colleagues for stepping up.

Do you like submarine canyons? Check out this nice pilot study we did in Astoria Canyon, offshore Washington and Oregon - led by graduate student Evan Lahr - that shows a dynamic sedimentary environment. 🤓 🧪⚒️ Just published in Marine Geology: authors.elsevier.com/c/1kqiT5mVe1...
Did someone say World Glacier Day? I still love this shot of our boat from field work in Prince William Sound, Alaska last summer. We were up there up there studying submarine landslides and will hopefully be back this summer. 🧪⚒️

Jan. 26, 2025, marks 325 years since the last great earthquake on the Cascadia subduction zone. We still have work to do to understand when the next great quake will occur & how to best respond when the shaking starts. The M7 Dec 2024 offshore quake & tsunami alert highlighted these shortcomings. 🧪⚒️

Faculty and staff at Sonoma State University were just notified of the closing of the Geology Department - they are organizing an email letter writing campaign for Monday 1/27 to rally support - see below🧪⚒️ It’s awful to see the closing of another Geology department and big loss for the community.
Just wrapped up a great 2 days of science 🧪 ⚒️ discussions at the #USGS Subduction Zone Science workshop with offshore and onshore observations in subduction zones to increase understanding of processes driving geohazards and communicating science to bolster societal resilience.
