This is a guest post by Erin McEwan.

River systems are shaped by both gradual and sudden geological processes, and the influence of active tectonics on river behaviour is a fundamental concept in tectonic and fluvial geomorphology. Despite this, much is still unknown about how earthquake surface deformation can alter flood hazard. This is concerning as human populations are increasingly expanding onto floodplains in seismically active regions. A recent review by McEwan et al (2025) in Earth-Science Reviews addresses this knowledge gap by analysing data from 52 sites where fault deformation is known to have induced an immediate change in river behavior; otherwise referred to as a Coseismic River Response (CRR).

The 2024 PATA Days took place from 6-11 October in Los Andes, Chile. This was the 11th meeting on Paleoseismology, Active Tectonics, and Archaeoseismology. The conference proceedings with all the 4-page abstracts in now available online and for download at https://libros.uchile.cl/1446.

Many thanks to the organisers for a successful conference and for the unforgettable field trips!
PATA Days are usually organised in the framework of INQUA’s TERPRO Commission.

Here are the latest papers on active tectonics and paleoseismology. Happy 2025 everyone! 

The 2025 Hokudan International Symposium on Active Faulting will be held online from 23-25 January, 2025. Abstracts are due December 25th, deadline for registration is January 15th. Please visit the meeting website for the circular and further information: https://home.hiroshima-u.ac.jp/kojiok/hokudan2025.html. The main theme will be “Active fault research for better preparedness for earthquakes”. Another session will commemorate the eminent researchers who contributed a lot for the past Hokudan meetings and who passed away since the 2020 meeting.

Jacek Szczygieł is looking for a Postdoc (2 years) for his project “Enhancing Paleoseismological Records through Multi-Methods Cave Deformation Analysis Tested in Diverse Hellenides Tectonic Regimes.” 

The postdoc will be responsible for coordinating and obtaining input data for the FEM analysis and performing FEM modeling of speleothems.

Application deadline is the 14th of January

In this month’s paper list there are a lot of studies on the US, Greece, and New Zealand, plus interesting stuff from Russia and China and on tsunamis. But don’t miss the methodological papers, for example on underwater photogrammetry. Happy reading!

There is PhD position with the Ngā Ngaru Wakapuke program in “Understanding earthquake sequences using near- and on-fault paleoseismology on the western Marlborough Fault System”. To work with leading paleoseismologists from VUW (J Howarth) & GNS.

These are the latest papers, and this time they really have a huge spatial coverage. Enjoy reading and let us know if we’ve missed something!

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!
