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.
This is the latest list of papers on paleoseismology and related fields. This time we have a lot of new studies on Eastern and Central Asia – very interesting reads! Enjoy reading and let me know if I have missed something.
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).
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!
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!
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!
Another 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/
A Special Issue is now open for submissions in the journal Land. The topic is “Historical Data for Natural Hazard Risk Mitigation and Land Use Planning“. Deadline for manuscript submissions is 30 September 2022. Guest editors: Fabio Luino, Mariano Barriendos Vallvé, Emmanuel Garnier, Fabrizio Terenzio Gizzi, Ruediger Glaser, Christoph Gruetzner, Walter Palmieri, Sabina Porfido, Heather Sangster, and Laura Turconi.
Paleoseismicity.org is a page dedicated to scientists and everyone else interested in paleoseismology, archeoseismology, neotectonics, earthquake archeology, earthquake engineering and related topics. Different authors irregularly write about recent papers, field work, problems, conferences or just interesting things that they come across. We intend to provide a platform for discussion and scientific exchange. Interested in joining as an author? Please contact us!
