Alexander Strom and Kanatbek Abdrakhmatov will run their famous summer school again after it had to be cancelled due to Covid-19. The summer school is designed for students and will take place from 14-29 August, 2023, in Kyrgyzstan. The topics include mass movements, neotectonics, and geomorphology in the epicentral area of the M7.2 1992 Suusamyr Earthquake. Find all the details in the announcement below.
moreThis is the last paper round-up in 2022. We have a lot of research on historical earthquakes and Asian tectonics. Don’t miss the new paper by Nurminen et al. on the updated surface rupture database. Enjoy reading!
(UPDATE 2022-12-02: I’ve added the new Alsop et al. paper because the free-to-read link expires in 50 days…)
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.
Continue readingThis 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!
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.
