For most of us the summer break is over and teaching, field work, and office work is starting again or has already started. Time to catch up with the latest papers I suppose! This time we have quite a lot of “classical” paleoseismology in our list, but also plenty of interesting remote sensing and tsunami stuff. Enjoy reading!

New paper by Zebari et al.: Late Pleistocene – Holocene slip rates in the NW Zagros
2021-08-26 | in PaperIn a recently published open access paper in TECTONICS, Zebari et al. report for the first time fault slip rates from Iraqi Kurdistan in the NW Zagros Fold-Thrust Belt. This area is challenging when it comes to narrowing down the distribution of S-N shortening and the associated fault slip rates, because in general, faults don’t reach the surface there. For this reason, we used a proxy: we dated uplifted river terraces with stimulated luminescence and used kinematic modelling of the Zagros fold belt. With this approach we can show that slip rate of the Mountain Front Fault is about 1.5 mm/a. Detachment folds take up another ~1.6 mm/a.

New papers on paleoseismology, earthquakes, and active tectonics (Aug 2021)
2021-08-02 | in PaperToday’s paper list contains a lot of interesting studies on Asian tectonics, a few articles on the Ridgecrest Earthquake, and a number of papers that I was involved in (sorry for the shameless self-promotion). Enjoy reading and let me know if I have missed something.

UPDATE 2021-08-03: Yes, I missed something. I added the last three papers by Rimando & Peace, Kempf & Moernaut, Amey et al., DePaolis et al., & Wils et al. -
Large-amplitude changes in water-levels facilitate earthquake-triggered mass failures in the Dead Sea Basin
2021-07-22 | in Paper | 2 responsesA recent study investigated seismogenic mass failure deposits that were preserved in a 457-m deep ICDP drilling (220-0 ka) from the Dead Sea depocenter. The study conducted a critical assessment and testing of the links between the occurrence of seismogenic mass failure, changes in water-level, and sedimentation rate driven by a changing climate.
1. Key Points:
more
• At the orbital- and millennial-scale, variable sedimentation rates are not a preconditioning factor for earthquake-triggered mass failures
• At the centennial- to decadal-scale, earthquake-triggered mass failures are not statistically correlated with lake-level state
• At the orbital- and millennial-scale, the mass failures are more frequent during lake-level high-stands with large-amplitude fluctuations -
New paper: Active faults in the Bolivian Amazon
2021-07-12 | in PaperThe Bolivian Amazon is a vast plain with almost zero topography. It hosts a huge and dynamic river system on the east side of the Andes. So far, little was known about the active tectonics of the area. In a new paper, Umberto Lombardo and I show that there are active faults parallel to the Andes, and also perpendicular to the mountain front. We used the TanDEM-X DEM and geomorphological analyses of the fluvial system to investigate the faults and their impact on river dynamics. We show that in such a low-relief setting, dip-slip earthquakes can catastrophically change river courses. If you don’t have the time to read the full paper, here’s a short summary.

New papers on paleoseismology, earthquakes, and active tectonics (Apr 2021)
2021-04-01 | in PaperJust as last month we have a veeeery long list today. Quite a number of papers deal with new data from Central Asia and S America, but of course there’s also something on the menu for connoisseurs of archaeoseismology, European, N American & African tectonics, and physics-based fault studies. Enjoy reading, stay safe and let me know if I’ve overlooked something.
