    See you all in Southern France!

  • Likelihood of primary surface faulting – spoiler of a PATA Days poster

    The Aix-en-Provence PATA Days are fast approaching and the meeting programme looks super-exciting! Unfortunately, I’ll not attend the congress, but my soul will be there in poster form – presenting author is 1st year PhD student Marco Pizza and the topic is the likelihood of primary surface faulting.

    Some earthquakes produce surface faulting, others do not. Several factors affect the outcome of this dichotomous variable (faulting YES/NO), including magnitude, depth, earthquake kinematic and local lithology. The probability of having surface rupture for a given magnitude is a key ingredient in Fault Displacement Hazard Assessment (FDHA). This probability is derived from empirical datasets and the state of the art is summarized in Figure 1, taken from the recently published IAEA Tecdoc on probabilistic FDHA.

  • Insights into sediment flow processes can help to better understand the feasibility of turbidite as an earthquake indicator in a specific subaqueous environment

    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).

  • New papers on paleoseismology, active tectonics, and archaeoseismology (July 2022)

    This 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!

  • New papers on paleoseismology, active tectonics, and archaeoseismology (June 2022)

    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!

  • Trenching season is ongoing!

    Following 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.

  • New papers on paleoseismology, active tectonics, and archaeoseismology (May 2022)

    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!
