We investigated homogeneous muds, turbidites, and debrites that were preserved in a 457-m deep ICDP drilling (220-0 ka) from the Dead Sea depocenter. Based on previous flash flood measuring, surface plume monitoring, and sediment traps monitoring in the lake center, we link homogeneous muds in the deep core to overflows, and link turbidites and debrites to underflows. The study bridges the gap between our understanding of modern sediment density flow processes and deposits preserved in a long-term geological record in the Dead Sea, a tectonically active subaqueous environment (Dead Sea rift zone).
moreThis time I found a lot of studies on tsunamis, including a whole book on tsunamis that affected the Iberian Peninsula. Then there’s classical paleoseismology of course and tectonic geomorphology, but also some discussion on science communication and news about earthquakes in the European Alps. Enjoy reading!

Below are some highlights on sessions centered on earthquakes, active faulting and tectonic stuff, but remember to check the full list – 209 proposed sessions!
Keep on reading!As Francesca has reported in her latest post, a lot of trenching is currently going on all around the world. Here you can read about previous trenching results that have now made it through review. Enjoy reading and have a great field season!
moreFollowing an un-systematic post-dinner doomscrolling I’m happy to declare May 2022 as the trenchiest month ever. Here’s some exhibits:
Safety first; if cozy and comfy it’s better.
The award goes to Stéphane Baize (@Stef_EQ_Geology) and their trenches along the Cévennes fault: look at the details in the photo… like “paleo” engraved in the wooden frame to prevent collapse of the trench wall. And what about the tent? 10/10 professional style.

Sorry if I missed someone, I wish you all a safe and fruitful field season!
Our paper list is full of classic paleoseismic trenching studies from all over the world – fascinating to see how quickly the number of trenches is rising. We also have papers on tools & methodology, and on earthquake proxies that open new possibilities to study past large events. Don’t miss Ferrario et al. who compiled 15 years of research on earthquake environmental effects!
moreAnother month has passed, new studies on earthquakes and active tectonics have been published. Enjoy reading!
By the way: Registration for the PATA Days in France is now open, but you’ll have to hurry: https://patadays-2022.sciencesconf.org/
Hungary plans to build a new nuclear power plant (NPP) at the banks of the Danube near Paks, where another NPP is already running for several decades. An interesting story is currently unfolding around the geological site conditions, and this story includes paleoseismology. In short, the Austrians and external experts argue the planned NPP Paks II will sit on a capable fault, while the Hungarians say there is a fault, but it can’t rupture the surface. Actually, it’s a bit more complicated…
