Last October I was given the chance to attend the “iRALL school on field data collection, monitoring, and modeling of large landslides” in Chengdu, China. During the school, we spent one week in the epicentral area of the Ms=8.0 2008 Wenchuan earthquake, where I was able to take some interesting pictures of earthquake damage and coseismic landslides. Then other things happened, like the earthquakes in Italy and New Zealand, with exciting sights from the field shared here, and I never ended up sharing my Wenchuan pics, which I want to do now.

Now that the new dates for the 8th PATA Days 2017 in New Zealand are fixed, it is time to bring to your attention an exceptional paper that was already published in 2016. I planned to write a review long time ago, but I just managed to do so now. The paper by Quigley et al. is not only likely to become your favourite read during the long flight to New Zealand, but it will also serve as an extremely valuable contribution to the study of earthquake environmental effects (EEEs) in general. The authors report on, and summarise, the effects that the 2010-2011 Canterbury earthquake sequence had on the environment. The paper is special in many ways: Continue reading “Paper: The Canterbury earthquake sequence and earthquake environmental effects”
Our friend and colleague Alessandro Michetti pointed me to this impressive video. It shows the surface ruptures of the 30 October earthquake from a helicopter: Continue reading “Italy earthquake: aerial view of the surface ruptures”
The EMERGEO Working Group has conducted extensive field work after the 24 August 2016 Amatrice Earthquake in Italy and put together a report on the coseismic effects. The report is in English and can be downloaded from the INGV earthquake Blog here: PDF (6.1 mb)
The report includes data on environmental earthquake effects like surface ruptures, fractures, landslides, and rockfalls. More than 2400 data points have been collected.

The Chilik-Chon Kemin Fault Zone is a major left-lateral strike-slip fault zone in Kazakhstan and Kyrgyzstan, just a few tens of kilometres east of Almaty and north of Lake Issyk Kul. It has seen one of the largest continental earthquakes ever recorded in 1889, with an estimated magnitude of ~M8.3. In July and August I had the chance to visit this fault zone for two weeks together with Angela Landgraf from Potsdam and Aidyn Mukambaev from the National Data Centre, thanks to a travel grant from COMET (thanks so much, COMET!) and with support from the EwF Project. We wanted to find out more details about the tectonic geomorphology of this fault zone and we wanted to study the slip rate and earthquake recurrence intervals. So we took our drone, shovels and picks and set off for a field trip into the mountainous wilderness. Since I will leave for another field trip to Kazakhstan (Dzhungarian Fault) tomorrow, I will leave you with some impressions from our field work and provide more information once the paper is published…
Enjoy! Continue reading “Studying the earthquake geology of the Chilik-Chon Kemin Fault Zone in Kazakhstan”
We would like to bring your attention to a workshop we are organizing on the topic of Fault Displacement Hazard Analysis (FDHA). The Workshop will be held December 8-9th at the U.S. Geological Survey Campus in Menlo Park, CA, and is timed to be the Thursday and Friday before the 2016 AGU Fall meeting so that international participants can plan to attend both the Workshop and AGU the following week.
Workshop themes will include: Continue reading “Fault Displacement Hazards Workshop, Dec 8-9th, 2016 (and AGU Fall meeting session)”
The geometry, length, and displacement of fault ruptures that breach the surface provide critical information on the behavior of faults during seismic events (coseismic deformation), and on their long-term behavior. The study of coseismic fault ruptures has concentrated almost exclusively along continental faults, while submarine studies have been scarce, and only a few provided quantitative constraints in parameters such as fault displacement (e.g., Tohoku Earthquake). In addition to represent more than two thirds of the Earth’s seismicity, submarine faults can also be associated with tsunamis, potentially increasing the seismic hazard that these structures pose.

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!
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… Continue reading “A Holocene surface rupture in Germany”
