A couple of interesting papers were published since my last round-up, including work on paleoseismology, tsunamis, measuring offsets, and boulder transport by storms. Enjoy reading! more

We published a new study dealing with paleoseismological work on the Milesi Fault near Athens, Greece. A slip rate was estimated based on GIS work, mapping, and trenching. Four surface-rupturing earthquakes in the last 4-6 ka were found, and we estimate magnitudes of around M6.2. With these input parameters, we developed a seismic hazard scenario that also takes into account site effects. Our results show that the official seismic hazard zonation in Greece, which is based on instrumental and historical records, contradicts geological data. We also show that extension in this region is not only confined to the Southern Evoikos Gulf graben system, but a significant amount of extension is accommodated by active faults closer to Athens. more

Our colleague Carlos Benavente Escóbar from the Instituto Geologico Minero Metalurgico (Peru) brought a book to my attention which was published in 2013: Neotectonics and seismic hazard of the Cusco Region. The book is in Spanish, but you will find it easy to understand what it’s about, because it is full of fascinating images of faults, fault scarps, seismites, liquefaction features, geological maps, and outcrop sketches. Have a look, it’s great! The book can be viewed online for free and is also available for download. more

A few days ago, SRL published a special issue on the Gorkha earthquakes with lots of interesting papers. I especially like the work of Angster et al. with their impressive photos of the earthquake ground effects. Make sure to download the electronic supplement to this article!

Besides this special issue, a good number of other interesting papers have been published recently on paleoseismicity, active tectonics, seismic hazard, and tsunamis. Among them is Andi’s work on the Ejina basin and Serva et al. with a introduction of using the ESI scale for earthquake hazard assessments. Enjoy reading! more

Several new studies have been published recently on old earthquakes and their geological footprint – time to list them and to recommend reading. Additionally, today’s paper digest also lists several articles which are not about paleoseismology, but geoethics. These papers were published in a special volume of GSL. They cover subjects that many paleoseismologists will have dealt with in the past or are likely to deal with in the future  – seismic risk perception, science communication, public outreach, and communicating uncertainties. One paper is dedicated to the L’Aquila trial. I find it very telling that this issue is not open access. Obviously, strengthening “public trust in geosciences” has still a long way to go…

Here are the latest papers:

Summer time is publishing time! Lots of new papers are out, today we have

• archaeoseismology & rotated objects;
• paleoseismology in Korea, China, & Portugal;
• trench photomosaicking and PBRs;
• lots of tectonic geomorphology (i.e., Ximena’s paper on the Carboneras fault where I did my diploma thesis in 2004…);
• news from the Balochistan earthquake; and
• tsunamis.

Enjoy reading and tell us if something is missing!

Here is my latest update on paleoseismology-related literature. Plenty of new hot stuff has been published, today we have: archaeoseismology & liquefaction in Corinth, incredibly good data from the Gorkha earthqukae (Nepal), an earthquake that deviated the Po River, paleotsunamis in Israel and Taiwan, notes about tsunami boulders, and tsunamis in Greece. Enjoy!

Is it just me or is the frequency of papers being published increasing…? Anyway, here’s the literature update with studies on paleoseismology and active tectonics. Today we have: Faulting in the Canyonlands, seismites from the Jurassic, a fake earthquake in Cologne, dynamic triggering, news from the San Jacinto Fault, ground motion variation between repeating earthquakes, metrics to evaluate seismic hazard maps, submarine tectonic geomorphology, the 1897 Great Assam Earthquake, and a collection of papers on geophysical imaging and interpretation of outcrops. Enjoy!

In 2013, a M_W7.7 earthquake struck Balochistan, caused a huge surface offset and triggered a small tsunami in the Arabian Sea. Immediately, the apparently strange fault behaviour caused the attention of scientists world wide and a number of papers were published. The discussion is highly interesting and still ongoing. This an interesting case for paleoseismologists, too, not only because of the cascading earthquake effects, but also because of the surface rupture distribution, from which we might learn some important lessons for our future work. Now my colleague Yu Zhou and his colleagues from Oxford University published a new paper on this event, arguing that it might be not as unusual as it seems. Their research is based on the analysis of Pleiades stereo satellite imagery, which has proven to be a very useful data source already. Yu send me a nice summary of his recent research: more

Lots of paleoseismology and tsunami studies are currently being published… Here’s my update on the latest papers, including: Surface ruptures, seismic swarms, tsunamites, Asian tectonics, slip rates and archaeoseismology. Plus: A very interesting study on the 1911 Chon-Kemin M8.0 earthquake in the Kazakhstan/Kyrgyzstan border region, the source process reconstruced from analogue seismograms. Thanks to Ramon Arrowsmith for pointing me to this one. Enjoy!
