Today’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 Basin2021-07-22 | in Paper | 2 responses
A 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

The 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.more

The Boletín de la Sociedad Geológica Mexicana has published a Special Issue “From the active fault to the seismic hazard in Latin America and the Caribbean“, edited by Laura Perucca and Franck Audemard. The issue includes studies on paleoseismology, earthquake geology, geophysics on active faults, geodesy, landscape evolution, and much more from all across S America and the Caribbean. All articles are open access! Check it out here: http://boletinsgm.igeolcu.unam.mx/bsgm/index.php/siguiente-numero-next-issue

Just 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.more
The Bulletin of the Geological Society of Greece (BGSG) is inviting papers for a Special Issue on the 2021 Northern Thessaly, Greece, Earthquake Sequence. This sequence included a M6.3 mainshock on March 3, followed 32 hours later by a M6.0 event and a M5.6 event on March 12, and thousands of smaller aftershocks. This was the most significant earthquake sequence in northern Thessaly in 80 years, and the first large events in this area of Greece since the major upgrades of the seismological, strong motion and geodetic networks. Remote-sensing imagery is available from a number of satellites and other platforms. The sequence raises numerous questions related to fault interactions, blind faulting, near- and far-field ground motions, damage distribution, earthquake triggering, liquefaction phenomena and seismic hazard and seismotectonics of the Northern Thessaly.more

A recent study investigated disturbances that preserved in the upper 260 m of a 723-m deep core drilled on the crest of a thrust-cored anticline in the western Qaidam Basin, NE Tibet.
1. Key Points:more
• We interpret micro-faults, soft-sediment deformation, slumps, and detachment surfaces as paleoearthquake/tectonic indicators
• The core records five seismite clusters between 3.6 and 2.7 Ma, revealing episodic thrusting in relation to intense regional deformation
• During the clusters, regional deformation was concentrated more in the fold-and-thrust system than along regional major strike-slip faults
