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.

This will be the last paper list of the year, time is flying. We have classical paleoseismological studies, historical earthquake research, a few papers on secondary effects, but also studies looking into more general physics questions of large earthquakes. Enjoy reading!

This 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!

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!
