This is the April edition of my paper round-up. Today I recommend papers on high-resolution topography data, fault mechanics, earthquake environmental/archaeological effects (liquefaction, rotated objects, landslides), Quaternary dating, a fault database for Asia, and tectonics of New Zealand and Martinique. Enjoy! more

It’s only one month since my last paper update and yet I have nineteen interesting new studies for you. Today’s round-up includes tsunamis, tectonic geomorphology, environmental earthquake effects and soft sediment deformation, new techniques/technology, and some classic paleoseismology. Enjoy! more
Guest blog by Sascha Schneiderwind (RWTH Aachen University): Multiparametric trenching investigations
[Update 15 February 2017: Since Sascha is an author here now, the post was attributed to him.]
Greece is one of the main targets of RWTH Aachen’s Neotectonics & Geohazards group. They worked on paleo-tsunamis, active faults on the Peloponnese, in Attica, and on Crete, and on the application of terrestrial LiDAR and shallow geophysics for active tectonics research. In their latest paper, Sascha Schneiderwind et al. developed a methodology to aid paleoseismic trenching studies. They use t-LiDAR and georadar to better and more objectively characterise lithological units. His paper includes nice examples from Crete and from the famous Kaparelli Fault. Here is his guest blog: more
I am quite happy that our new paper has finally been published in GJI. We worked on a fault between Aachen and Cologne in Germany and found that there has been a surface rupturing earthquake less than 9000 years ago, and possibly not much older than 2500 years BP. The area is of interest also because in 1755/56 a series of damaging earthquakes hit Düren and its surroundings – these are the strongest historical events in Germany that we know of. The quakes were felt as far away as Berlin, Strasbourg, and London, yet there were no primary ruptures. “Our” quake must have been much stronger… more

Here’s the February edition of my paper recommendations. This time we have:
- Paleoseismology in Germany and Nepal (the latter with a focus on charcoal dating techniques),
- Tsunamis in Greece, Portugal, Israel and Alaska,
- Turbidites in Portugal,
- New insights into the geodynamics of Mozambique,
- Fault rheology in Iran,
- Rupture jumps on strike‐slip faults, and
- A MATLAB tool for seismic hazard calculations.
Paleoseismology & active tectonics sessions at the IASPEI-LACSC meeting 20-22 June, 2016, San Jose, Costa RicaJanuary 24, 2016 | in Meeting
From 20-22 June, 2016, the IASPEI – Regional Assembly of the Latin-American and Caribbean Seismological Commission – LACSC will be held in San Jose, Costa Rica. There will be some very interesting sessions on active tectonics, paleoseismology, seismic hazard, and intraplate faults: more

Plenty of paleoseismology papers have been published in late 2015 and early 2016 already! Especially those on the Gorkha earthquake made it to the news (Science and NatureGeoscience), but there is much more to discover. Check them out and – as always – tell us what we’ve missed. more
Dear friends and colleagues,
The 7th International Workshop on Paleoseismology, Active Tectonics, and Archaeoseismology (PATA Days) will be held in the USA from 30 May – 03 June, 2016. The workshop is sponsored by the INQUA-TERPRO Commission and mainly organized by James McCalpin. The workshop includes several excursions and we welcome presentations on a broad list of topics related to seismic hazards and active tectonics: more
A few weeks ago, Nadine Reitman (USGS) published an interesting paper about the use of Photogrammetry for Paleoseismic Trenching in BSSA. In this guest blog she shares her key findings and explains how to minimise errors without spending too much time measuring control points. Thanks Nadine!
Structure-from-motion (SfM) is now routinely used to construct orthophotos and high-resolution, 3D topographic models of geologic field sites. Here, we turn SfM on its side and use it to construct photomosaics and 3D models of paleoseismic trench exposures. Our results include a workflow for the semi-automated creation of seamless, high resolution photomosaics designed for rapid implementation in a field setting and a new error analysis of SfM models. more

This is this year’s last issue of my paper round-up, and it includes some pretty interesting stuff. Our Greek colleagues published a report on the liquefaction caused by the 2014 Lefkada earthquakes, just in time with the recent earthquake that hit more or less the same area again (Papathanassiou et al., and see earlier posts here). Long et al. published a paper on iceberg-induced tsunamis, found in the sedimentary record – that’s a great story, isn’t it? Jacobson’s PhD on the Lake Heron Fault (NZ) is an interesting read, and Iván Sunyol’s paper on paleoseismological trenches in Mexico is especially interesting for those who attended the 2012 Morelia meeting. Zhou et al. come up with a great dataset of Pléiades imagery from the El Mayor-Cucapah Quake, Calais et al. have a close look on the northeastern Caribbean, and finally, Kufner et al.’s paper is about the collision between India and Asia deep below the Pamir and Hindu Kush.
Enjoy reading and Merry Christmas!
