Here’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?

New Paper: Holocene earthquakes near Cusco, Peru
2023-12-08 | in PaperIn a new study, Rosell et al. look into the earthquake history of the Tambomachay Fault near Cusco in Peru. Cusco has been hit by damaging earthquakes in 1650, 1950, and 1986, and there is also some evidence for another earthquake during Inca times between AD 1418–1471. Very little is known about the causative faults. There is also very limited information on older events. The closest fault to the city is a 20 km-long normal fault at the northern margin of the Cusco Basin, the Tambomachay Fault. Here we constrained the fault’s Holocene slip rate by dating offset lateral moraines, and we identified three Holocene surface ruptures in a paleoseismological trench. The study was recently published open access in τeκτoniκa.
