Today’s paper round-up is rather short. Maybe this is due to the start of the field work season and many editors being involved in field research, maybe it’s just holiday season. Maybe I’ve missed some papers because I have been in the field, too. However, there are some very interesting studies, especially concerning tsunamis. Enjoy reading and please tell me what I’ve missed in the comments.
It’s June and it’s time for a new paper round-up, isn’t it? When I compiled the list during the past weeks I already realized that there’s a lot of new literature out there, and I guess this month’s post is probably the longest list we’ve ever had – 21 articles! So here are the latest papers on paleoseismology, tsunamis (maaaany tsunami papers this time), and active tectonics. As always: Any suggestions are highly appreciated. Enjoy reading!
Some weeks ago we published a new study on the classification of earthquake-induced landslide event sizes based on seismotectonic, topographic, climatic and geologic factors. Our idea was that this classification could be used to help improve seismic hazard assessment by contributing to a better prediction of landslide hazards induced by an earthquake when the geologic, topographic and climatic context is well defined. Possible applications could be the short-term prediction right after an earthquake or scenario modeling, e.g. for critical infrastructure. Since earthquake triggered landslide event sizes are also an important proxy for the estimation of magnitude and intensity of past earthquakes, I thought our study might be interesting for the paleoseismicity community as well, and so I put together a brief summary.
Today’s paper round-up covers a very wide spectrum of earthquake related studies. We have work on tsunamis, turbidites, and lake paleoseismology, paleoseismological data from Asia, Archaeoseismology, mud volcanoes, the ESI-2007 scale, and an explanation on what the rise of the Andes is driven by.

On 16 April an earthquake of magnitude Mw7.0 hit the district of Kumamoto, Kyushu Island, Japan. The quake was preceeded by a Mw6.1 foreshock one day before. It occurred on the ENE striking, right lateral Futagawa-Hinagu fault zone. Our colleague Koji Okumura from Hiroshima University has prepared a short report on this surface-rupturing event. Download the report here (PDF, 612 kb). The report will be continuously revised and corrected, so check for regular updates. Thanks Koji for providing this summary!
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

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
Tsunamis are a very real threat in the Indian Ocean. Most people will immediately think of the 2004 tsunami and the Sumatra subduction zone, but the Arabian Sea has seen strong tsunamis in the past, too. In 1945, a major earthquake at the Makran Subduction Zone caused a large tsunami (Hoffmann et al., 2013a). In 2013, the on-shore Balochistan earthquake caused a submarine slide which in turn triggered a tsunami that reached the coast of Oman (Heidarzadeh & Satake, 2014; Hoffmann et al., 2014a). There is also evidence for paleotsunamis along Oman’s coast (Hoffmann et al., 2013b; Hoffmann et al., 2014b). Now a team of scientists from RWTH Aachen University (Germany) and GUtech (Muscat, Oman) have published a tsunami inundation scenario for Muscat (Schneider et al., 2016). This is lead author Bastian Schneider’s guest blog on this research: 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
