I was once a little pain the ass, gym rat, point guard at Chico High in Chico, CA. I found this article while visiting home and it brought those memories flooding back 🏀

Snuck in a little CPAL fieldwork while the @cascadiaeqs.bsky.social Cores to Code undergrads were busy modeling with @diegosismologo.bsky.social. Just a little light work mapping 1700 CE tsunami sand at Lagoon Creek, CA 🌊🌊

The @cascadiaeqs.bsky.social Cores to Code students have been busy in the lab processing sediment cores, compiling site stratigraphy, running loss on ignition, and conducting foram and diatom analysis! They’ve been star researchers, remaining engaged and enthusiastic throughout the process!

Grundens day. Dare I say these were even more comfortable than the Carhartt overalls? And you can sit in the mud and not get wet. Where have these been all my paleoseismology life? 🌊🌊

Great first few days in the field with the @cascadiaeqs.bsky.social Cores to Code undergraduate research program. The students are already expert paleoseismologists! We took cores, described stratigraphy, and they found their first earthquake evidence! All in a good few days work in Humboldt Bay 🌊🌊

Fun drive from Coos Bay to Arcata today. It was foggy/sunny/windy just like it should be. Here I am freezing my booty off at Cape Blanco, doing my important job of warding off that 1000 foot mega tsunami*!
*Mega tsunamis are not a thing and we don’t expect anything larger than 100 feet at Cascadia 😎

Great first day of the @cascadiaeqs.bsky.social Cores to Code undergrad research program! We’re road tripping down the Oregon coast on our way to NorCal. We discussed Siletzia, wave cut terraces, and relative sea-level change at Cascadia. It was a solid day with a great group! 🌊🌊 @vt_geosciences

I’ve been on vacation but I got some news alerts that our earthquake-driven subsidence paper was being cited in some mega tsunami warnings 😳 A friend of mine then sent me this reel from @geopetalfabric.bsky.social debunking the news articles, complete with the f-bombs that I was saying in my head!

It’s been a crazy week professionally with the release of our paper and the media frenzy around it! The headlines started out reasonable, then fully left containment. A fascinating journey through our current media landscape🙃. Here’s the paper behind the headlines ICYMI!

🌊 But if a big earthquake happens in 2100, the combined effects of subsidence + sea-level rise could triple today’s flood exposure—expanding floodplains by 370 km² (145 mi²)! 🚨 (6/🧵)

🌡️ Key Finding 2: Climate change compounds the problem. Even if no earthquake happens, sea levels are rising—projected to rise 1.3–2.9 ft (0.4–0.9 m) by 2100. This alone would expand coastal floodplains by 100 km² (40 mi²). (5/🧵)

⏳ And it’s not just temporary—post-earthquake land recovery could take decades to centuries. That means long-term changes in how we think about flood risk and coastal planning. (4/🧵)

📍 24 major estuaries studied—new flood exposure depends on how much the land drops:
🟡 Low subsidence: +90 km² (35 mi²)
🟠 Medium subsidence: +160 km² (60 mi²)
🔴 High subsidence: +300 km² (115 mi²)
More people, roads, and buildings will be in the flood zone. (3/🧵)

🔍 Key Finding 1: Earthquakes lower the land—for decades to centuries after an earthquake. If a Cascadia earthquake happened today, coastal land from Washington to California could drop by 0.76–8.76 ft (0.23–2.67 m). This instantly expands floodplains, leaving communities more exposed. (2/🧵)

This week I got an article accepted for publication in PNAS, and I made a diorama with my 7yo son. One took significantly more effort and patience than the other, and it wasn’t the high-impact scientific study. Allow me to humblebrag about our epic Wright brothers Montessori potato project diorama 😂

Huge congratulations to @dbruceite who successfully defended his PhD this week! He’s a rock star and crushed his defense and we’re all so proud of him. Hopefully he’ll start his Mendenhall soon. In the meantime he’ll be postdocing with us 🌊. Great job, Dave! 🚀🚀🚀#coastalhazardslab #allgasnobrakes

We are about a month out from the Feb 15th due date for the @cascadiaeqs.bsky.social Cores to Code undergraduate summer research experience. Come and join us in the field and in the lab at Cal Poly Humboldt for some paleoseismology fun! Program runs June7-28 🌊 cascadiaquakes.org/geoscience-e...

Had a great time at the at the USGS Subduction Zone Science meeting in Seattle. I presented our earthquake subsidence and sea-level rise work, Bering presented her CRESCENT affiliated project, and Dave presented his Coquille River downcore subsidence work. A subduction zone science extravaganza! 🌊
