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.

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!

Here is the 2nd circular for the PATA Days in Southern France, September 2022.
First important deadline: 30 April for submitting the short abstract (300 words).
For more information visit http://patadays-2022.sciencesconf.org

Here we are with the latest list of papers on paleoseismology and active tectonics, and we start with a surprise: A published paper on the 8 January 2022 Ms 6.9 Menyuan earthquake! A mere three weeks after the event, Yang et al. have already managed to get their rapid report accepted. Spoiler: It includes an offset animal footprint trace in snow! But there’s a lot of other interesting stuff in the list, too – check it out!

Frontiers in Earth Sciences plans to publish a new Special Issue (Research Topic as they call it) on “Seismically deforming active plates above active subduction zones: geological, paleoseismological and geodetic perspectives”. Deadline for abstract submission 31 March, 2022. Guest editors of this SI are Alessandro M. Michetti, James McCalpin, Jenni Robertson, Silvia Brizzi, Jorien van Der Wal, and Marco Meschis.

Which journals do we normally chose for a neotectonics or paleoseismology paper? Sounds like a simple question, but the answer is not straight forward. Often, local journals are a great place, such as The New Zealand Journal of Geology and Geophysics, or society journals such as SRL, BSSA, and Quaternary International. Then there are the usual suspects: JGR, GJI, Tectonics, Tectonophysics, Geomorphology. If the story is a bit bigger we often go for EPSL or even the 4-page journals. Recently, several new players have appeared such as Frontiers or Scientific Reports, and I am also closely following the new diamond open access initiatives We Are Seismica and We Are Tektonika. In 1986, Wiley made an attempt to collect these kinds of studies in one place and launched NEOTECTONICS. Sadly, the journal only saw one single issue and was then discontinued. Today, you don’t find a trace of this journal any more, and searching for the single papers of the issue does not yield any results. Alan Nelson made me aware of the existence of this journal and somehow a copy found its way onto my desk. Here’s the list of papers that was published in the most exclusive of all neotectonics journals:

Happy New Year everyone! May 2022 bring you health and joy, and may you always encounter nice reviewers and great outcrops. Enjoy reading our latest selection of active tectonics & paleoseismology papers.

Soft-sediment deformation structures are often used as evidence for paleo-earthquakes. When several deformed horizons are present, one has to ask whether repeated slope failure at the sediment surface has built-up the stratigraphic record. Another option would be that a single failure event could have concurrently created surficial and sub-surface deformed horizons at different stratigraphic levels. The implications of these differing models are important for the timing of palaeo-earthquakes. In a new paper, Alsop et al. used the late Pleistocene Lisan Formation from the Dead Sea Basin to catalogue and establish key criteria that help distinguish surface versus sub-surface intrastratal deformation of soft-sediments. The paper is available for free for 50 days!

A new special issue has been published in Frontiers. While most of paleoseismological studies deal with onshore faults for obvious reasons, this collection of 15 studies is all about offshore faults. The papers are of course full of wonderful high-resolution bathymetry data and shallow seismic profiles, but they also deal with the important question of how to implement these data into seismic hazard assessments and how to deal with the patchy fault information. The study areas cover marine settings and lacustrine environments.

This months we have a lot of studies on Mediterranean tectonics, first of all from Italy, and many papers on China and the US. Besides, there are some interesting methodological studies and research from areas that had recent seismic crises such as Puerto Rico and Thessaly. Enjoy reading!
