More 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!

Geomorphic 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.

This month’s paper list has an usually large number of studies on active tectonics of the Balkans and southern Europe. Is this a sampling bias? Perhaps. Don’t hesitate to send recommendations if you publish something cool that you’d like to see included. Enjoy reading!

I’m a bit late this month, so the list is a bit longer. This time we have lots of coastal and offshore studies, even a seafloor earthquake rupture! Enjoy reading.

For many geologists the field season is up ahead or has already started, but perhaps you will find some time to read through the latest literature? Or you can use the winter season in the southern hemisphere to enjoy a good read? It would be a pity to miss some of these really interesting studies. Enjoy!

This month’s list of papers includes the first few studies on the devastating earthquakes in Türkiye in February, 2023. Apart from that, we also have important work in archaeoseismology and great studies from New Zealand, an interesting shallow earthquake in the Tarim Basin, updates on surface displacement hazard and strain rate estimations, and papers on the Med and East Africa. Enjoy reading!

A new paper has been recently published in Quaternary International, summarizing the “New developments in onshore paleoseismic methods, and their impact on Quaternary tectonic studies”.

The paper is the result of a cooperative effort (12 authors from 6 different countries and 3 continents) led by Jim McCalpin. Sorry for the paywall, feel free to contact me or the other authors – we will be more than happy to share our work!

The first papers related to the 6 Feb, 2023, Türkiye Earthquakes are already published, but this month’s list has also interesting studies on Asian tectonics, the Med, and the Americas. Enjoy reading!

A new special issue has been published in Quaternary International. Earthquake Geology and Seismic Hazards: From Earthquake Mapping of Historical and Prehistoric Earthquakes to Paleoseismology contains contributions from the PATA Days in Greece, 2018, and the INQUA Congress in Dublin in 2019. The SI collects an editorial and six research papers:

This is the longest list of papers we had since ages. We start with a brand new review article on recent developments in onshore paleoseismology by Jim McCalpin et al. Also in the list are plenty of papers on  classical paleoseismology and earthquake geology, a few cool tsunami studies, some fault physics, SHA, and new methods. Enjoy reading!
