The 16 World Conference on Earthquake Engineering will be held from 9-13 January, 2017, in Santiago de Chile. Note that the deadline for short abstracts submission is 23 November, 2015! Abstracts can be submitted via this link.
This meeting comes with a number of sessions which are interesting for earthquake geologists, paleoseismologists and those of us who deal with seismic hazard assessments. Among them: Continue reading “Earthquake Geology sessions at the 16 World Conference on Earthquake Engineering, Chile, 2017”
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!

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
Enjoy reading and tell us if something is missing!

In 2013, a MW7.7 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: Continue reading “Guest blog by Yu Zhou (Oxford): The 2013 Mw 7.7 Balochistan earthquake in Pakistan: NOT SO UNUSUAL”
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!

A few weeks ago I spent ten days of field work in the Suusamyr Valley in Kyrgyzstan. In the framework of the EwF Project and COMET a team from Oxford (Eleanor Ainscoe, Austin Elliott, Richard Walker) and Kyrgyzstan (Kanatbek Abdrakhmatov, Azat Moldobaev) re-visited the epicentral area of the 1992 MS7.3 Suusamyr earthquake. This thrust earthquake is quite special for it produced intense and widespread secondary earthquake environmental effects (landslides, rockfalls, secondary ruptures, mud eruptions, etc.), but remarkably short primary surface ruptures only. Actually, surface ruptures of several metres height were found near the Suusamyr river, but limited to few hundreds of metres in length. Some 25 km to the west, another set of surface ruptures appeared, which were only about 1 m in height and less than 3 km long. Here are some impressions from our field work.

Earthquake Environmental Effects (EEE) have proven to be valuable for describing past earthquakes and their geological imprints. The ESI2007 is a relatively new intensity scale dedicated to such effects, but also integrating traditional macroseismic scales. Examples of ESI2007 intensities assigned to large earthquakes are being collected in the EEE web catalogue hosted by the ISPRA and ESI2007-related work is conducted in the framework of INQUA.
Another milestone now has been achieved with the ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue”. This book is now available online here. It contains updates on the ESI2007, examples of applications, documentation of the EEE Android App, a huge reference list and, most importantly, the ESI2007 description in ten languages: Continue reading “ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue””
In the last two posts I have reported on the scientific sessions of the Fucino15 conference and on the first of the field trips. This post is about the L’Aquila field trip. I haven’t been to this city before and I was curious to see the place that sadly became so famous in earthquake science. I was surprised by how many heavily damaged buildings were still standing and by the overwhelming amount of historical buildings that await their reconstruction. We were given a great tour through the Palazzo Ardinghelli which is currently being rebuilt, then we had a look at the worst-affected parts of the city. Here’s a report in images.

Phew, this was an intense week and a great one too! The Fucino15 meeting on paleoseismology, active tectonics and archaeoseismology is over and hopefully everyone safely arrived back home. Here’s a brief report on some of the science that happened at the meeting. Since we had ~50 oral presentations, only an overview is possible here. In the following days I’ll add more details about the field trips. A big thank you to the Italian organizing team who did an amazing job – grazie mille!

It’s been a while since the last update on paleoseismology literature. BSSA’s latest issue has some interesting studies that you should check, and there’s even more to discover. Also, there is some new work on (paleo-)tsunamis and historic large earthquakes. If you feel that important new papers are missing, drop us a mail! Continue reading “New paleoseismology papers”
