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”
It’s a busy summer for me with lots of field work going on, but there’s still time to read the latest papers on paleoseismology and earthquake geology. Here’s my latest paper round-up. No tsunami papers this time, I am sorry. Enjoy reading and as always, please don’t hesitate to tell me which papers I have missed.

The 7th International INQUA Workshop on Paleoseismology, Active Tectonics and Archaeoseismology (PATA Days) took place last week in Crestone, CO. The meeting was organised by Jim McCalpin who did an amazing job – thanks Jim for inviting us to Crestone and for this wonderful conference. Prior to the meeting a six-day road trip to the Faults of the Wild West lead a group of ~20 people to the legendary sites of western US faults: Borah Peak, the Tetons, Wasatch, etc. On 29 May most participants gathered in Denver where the icebreaker took place. Early in the morning next day we started with a pre-meeting field trip to Crestone, driving into the Rocky Mountains, passing South Park, and arriving at Crestone just on time for lunch.

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!

Between 1885 and 1938, the northern Tien Shan at the border between present Kyrgyzstan and Kazakhstan experienced a remarkable series of five major earthquakes, exceeding M6.9 and reaching up to M ~ 8 (1885 Belovodskoe M6.9, 1887 Verny M7.3, 1889 Chilik M~8, 1911 Chon Kemin M8, and 1938 Kemino Chu M6.9). Combined, the seismic moments add up to almost moment magnitude 9, which is a significant amount of strain released in roughly 50 years and across an E-W stretch of less than 500 kilometers. Even more intriguing is the fact that the ruptured region is located more than thousand km north of the nearest plate boundary and associated India-Eurasia collision zone. The macroseismic areas of these earthquakes include the present-day capital of Kyrgyzstan, Bishkek (Frunze) and the former capital and still largest city of Kazakhstan, Almaty (earlier names Alma Ata and Verny).

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! Continue reading “New papers on paleoseismology, tsunami, and active tectonics (Apr 2016)”
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!

[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: Continue reading “Guest blog by Sascha Schneiderwind (RWTH Aachen University): Multiparametric trenching investigations”
