This month’s list has everything: classic paleoseismology, tsunami studies, archaeology and historical seismology, lake turbidites from the Alps, deformed soft sediments, folds and faults, tidal notches and geodesy, etc.. Enjoy reading and drop me an email in case I have missed something.
moreHere’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.

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 PATA Days are the meeting on Paleoseismology, Active Tectonics, and Archaeoseismology, organised within the framework of INQUA‘s TERPRO commission. The official website has been launched, containing all infos on the programme, field trips, grant applications, the venue, the abstract template, and the deadlines. Check it out: https://www.patadayschile.cl.
Abstract submission will open 4 March and the deadline for the 4-page abstracts is 29 March. No short abstracts this time.
See you all in Chile in October!

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!
