We have a new paper out in QSR! Paleoseismic evidence for the 1730 Mw ≥9 Chile earthquake in a former coastal lagoon: an infrequent, shallow, tsunamigenic rupture with plausible near-term recurrence www.sciencedirect.com/science/arti... Led by Dr. Marco Cisternas from the PUCV in Chile

Paleoseismic evidence for the 1730 Mw ≥9 Chile earthquake in a former coastal lagoon: an infrequent, shallow, tsunamigenic rupture with plausible near-term recurrence

We report the first paleoseismic evidence jointly documenting coseismic subsidence and tsunami inundation from the 1730 Chile earthquake (Mw ≥ 9) and …

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. 🎙️ Listen here →https://podcasts.apple.com/us/podcast/cascading-risks-and-a-cascadia-mega-quake-with-dr-tina-dura/id1825669405?i=1000719788046

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/...

An opinion piece by Diego Melgar on the recent Russia earthquake and early warning systems was featured on MSNBC today. Check it out here: www.msnbc.com/opinion/msnb...

Opinion | The Pacific tsunami response is a warning about federal funding for science

The better the warning systems perform, the less visible their value becomes — until those systems fail.

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. 🧪⚒️

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. www.pnas.org/doi/10.1073/... www.nature.com/articles/s41...

Changes in earthquakes due to glacier loss and other factors affected by climate change (e.g. monsoon rains) tend to be fairly small and mostly effect smaller magnitude earthquakes. They make no practical difference on large subduction zone earthquakes like yesterday's.

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. 🧪⚒️

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 🏀

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!
