These are the latest papers that deal with earthquakes, tsunami, archaeoseismology, and active tectonics. Quite a number of studies from the Americas this time. Enjoy reading and let me know in case I’ve missed something. Also: If you’d like to write a post about your research, a new paper, a good tectonics field trip or the like, please get in touch!

New papers on paleoseismology, active tectonics, and archaeoseismology (Aug 2024)
2024-08-01 | in PaperThese are the latest papers that I came across last month. This time we have a number of studies on strong historical earthquakes and their geological (and archaeological) record, classical paleoseismology that sometimes worked, sometimes not, tectonic landscapes, and much more. Enjoy reading!

New papers on paleoseismology, active tectonics, and archaeoseismology (July 2024)
2024-07-01 | in PaperQuite a number of articles in this month’s paper list are concerned with what happens or happened offshore in strong earthquakes. But of course there is a also a lot of classical paleoseismology and some new approaches to dating fault slip directly from the fault gouges. Enjoy reading and drop me a note if I have missed something.

New papers on paleoseismology, active tectonics, and archaeoseismology (April 2024)
2024-04-01 | in PaperHere’s the latest list of papers. Geographically, it’s really diverse this time, from Greenland to San Andreas, S Africa, the Caucasus and back. Also in time dimension – perhaps we have the oldest paleoseismicity in our list today? Enjoy reading and let us know if we’ve missed something.

The Paleoseismic EArthquake CHronologies – PEACH – code, a new tool to model paleoseismic dataset correlations
2024-03-19 | in Paper, Software and ApplicationsThis is a guest blog by Octavi Gómez-Novell, Universitat de Barcelona, visiting researcher at Universidad Complutense de Madrid (Spain). Contact: octgomez@ub.edu
Paleoseismic data are punctual and highly localized in defined fault strands, while earthquake surface ruptures cover much larger and complex regions in comparison. This makes the identification of paleoearthquakes in trenches strongly dependent on the slip that those particular events had at each trench site, as well as on the continuity and quality of the stratigraphy for those paleoearthquakes to be dated and well-constrained in time. For this reason, paleoseismologists always seek to increase observations by trenching several sites along fault deformation zones with the premise that more observational data might: 1) complete the paleoearthquake catalogues closer to the real event count that actually occurred, 2) reduce the event age and detection uncertainties and 3) give insight about surface rupture characteristics. While all of these premises are correct and proven successful in several cases, the truth is that in a handful of other cases increasing observations can significantly difficult the correlation of datasets between sites, making such interpretations highly subjective. For instance, in very populated paleoseismic datasets and/or those with large event date uncertainties there will be multiple correlation options; which is the right one? After all, even though based on observations, paleoseismic data are interpretations, hence models that should be treated as such. Thus, can we improve correlation using numerical modelling?

The QUIN project
2024-02-20 | in Paper, Software and ApplicationsThis is a guest post by Simone Bello from the Università degli Studi G. d’Annunzio Chieti e Pescara, Italy.
The QUIN project (QUaternary fault strain INdicators database) stems from the initiative of a group of researchers to make the structural-geological data of the potentially seismogenic faults cropping out along the entire Apennines in Italy available to the scientific community.
Strain and regional stress databases of active deformation patterns are largely available in the literature but are almost exclusively derived from earthquakes and geodetic data. However, in areas such as Italy, where the regional stress field has remained unchanged over the last few million years, the analysis of structural data relevant for seismogenic purposes can be extended at least to the overall Quaternary time interval. QUIN was born with this assumption. It is designed to integrate, unify, and elaborate high-detailed geologic information on potentially seismogenic faults and provides data on the location, attitude, kinematics, and deformation axes of Fault Striation Pairs (FSPs) measured along Quaternary faults.
