🚨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/🧵)

The tsunami may last hours.
But the subsidence?
Dr. Tina Dura joins the Risky Science Podcast to explain why flood maps and risk models aren’t ready.

First day of school! Year 7 at Virginia Tech. The year I was hit with the readers 😆🤓🌊 Let’s go, HOKIES! 🦃

It's also annoying because that paper is about sudden land subsidence and not tsunamis or quake probabilities as such. They do note established quake models and that if you are suddenly two metres lower than you were before your tsunami risk just increased a lot. www.pnas.org/doi/10.1073/...

New documentary short just dropped!

@pbs.org updated their video about a Cascadia subduction (not seduction) zone earthquake and tsunami with new research from @diatomdura.bsky.social and team!

How many likes to get you to stop? 😆 I joke, it’s interesting to follow. Also terrifying this is all in your brain.

Just to illustrate how long waves from a #tsunami can keep going, this is a tide gauge record from Crescent City CA (known for its sensitivity to tsunami waves due to bathymetric and resonance effects) showing significant wave activity still continues 24+ hours after their first arrival. 🧪⚒️

We've shown this in a few recent studies—one showing how sea-level rise will make distant tsunamis from Alaska more impactful in southern California, and another showing how earthquake-driven coastal subsidence will flood far more land in places like Oregon and Washington as the century progresses.
diatomdura.bsky.social
As sea level rises, coastal communities are starting out closer to the water—before any earthquake or tsunami occurs. So when a tsunami does hit, it doesn’t need to be as big to cause flooding. And when an earthquake causes coastal subsidence, future sea-level rise will amplify flood exposure.

Totally agree. Climate change isn’t causing big subduction earthquakes. But it is raising baseline sea levels along our coasts, and that makes the impacts of those earthquakes and tsunamis worse when they do happen.

Another quick comparison of the 1952 #Kamchatka #earthquake from MacInnes et al. (2010) with today’s M8.8 event. The aftershock areas are similar, as well as one region of foreshocks. The updated USGS rupture model has a max slip of 10m versus 12m for 1952, with SW rupture direction. 🧪⚒️

We are delighted to announce the release of the CRESCENT Cascadia Paleoseismology (CPAL) Viewer, a web-based platform for mapping, cataloging, and visualizing paleoseismic datasets associated with past earthquake evidence along the Cascadia Subduction Zone. ⬇️
