In 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.

Call for papers: Special Issue on “Earthquakes and active tectonics in regions of slow lithospheric deformation: towards a re-evaluation of Stable Continental Regions (SCRs)”
2023-12-05 | in Meeting | one responseDear Colleagues,
We are aiming to organize a special issue titled: Earthquakes and active tectonics in regions of slow lithospheric deformation: towards a re-evaluation of Stable Continental Regions (SCRs). This special issue will complement a session on Intraplate Tectonics and Seismicity at the 37th International Geological Congress to be held in Busan, Korea in September 2024. The abstract for the IGC session is below, followed by our solicitation for contributions to the special issue. If you are interested in submitting an article to the special issue, please let us know a tentative title your list of authors by the 15th of December 2023.
We hope that you will join us in Busan and consider submitting your intraplate research to our special issue.
Sincerely,
The editors: Klaus Reicherter, Beau Whitney, Sambit Naik, Pierre Arroucau, Christoph Grützner, Stéphane Baize, Jim McCalpin

New papers on paleoseismology, active tectonics, and archaeoseismology (Nov 2023)
2023-11-01 | in PaperThis has become a long list again, and I partly blame the New Zealanders who are currently publishing a lot of studies related to their new hazard model. Really cool work! But of course the inclined readers will also find other gems for their taste. As always – please send me paleoseismology studies that I have missed. Enjoy reading!

Save the date: 12th INQUA PATA Days will be held in Los Andes, Chile, 6-11 October, 2024
2023-10-30 | in PATA days | 7 responsesThe 12th international PATA Days will be held in Los Andes, Chile, 6-11 October, 2024. PATA stands for Paleoseismology, Active Tectonics, Archaeoseismology and it is the main activity of the paleoseismology community within INQUA’s TERPRO commission.

New papers on paleoseismology, active tectonics, and archaeoseismology (Oct 2023)
2023-10-07 | in PaperMore and more papers emerge on the February, 2023 earthquakes in Turkey and the East Anatolian Fault System. Additionally, we have a database of paleoseismology studies in New Zealand (spoiler: it’s a lot!) and many more papers on paleoseismology and tectonic geomorphology. Enjoy reading!

New paper: Why geomorphic indices often fail in active tectonics studies
2023-09-17 | in Paper | one responseGeomorphic indices can tell us about the tectonic activity of an area. The idea is that the landscape records the signal of active tectonics, for example in its river network, in its erosion pattern, or in its roughness. Geomorphic indices allow us to quantify this, that is, we can use standard algorithms to calculate numbers from a DEM that say ‘active’ or ‘inactive’. This is very attractive because essentially, all that is needed is a DEM and a GIS (and perhaps MATLAB). The number of papers on geomorphic indices is currently exploding, and I guess the fact that the method is so cheap and easy to apply plays a major role in that. No expensive field work, still meaningful results. But is this always true? In a new open access paper, we argue that without ground checking, probably not, at least in many cases.

AGU Session S014 – Field observations, instrumental and high-resolution satellite imaging: A vision of improved active tectonics/paleoseismology hazard assessment.
2023-07-24 | in MeetingAGU has lots of interesting sessions to offer for paleoseismologists. Our colleague Pia Victor invites contributions to her session with Shreya Arora, Laurence Audin, Christie D Rowe, Alba Mar Rodriguez Padilla: Field observations, instrumental and high-resolution satellite imaging: A vision of improved active tectonics/paleoseismology hazard assessment.
