  • New papers on paleoseismology, tsunami, and active tectonics (Sep 2016)

    Today’s paper round-up has lots of tsunami papers, including one on the use of DNA to decipher paleo-tsunami deposits. Also, we have some papers about Italy, even from the area of the 24 August Amatrice earthquake. Enjoy reading and please don’t hesitate to tell me which papers I’ve missed.

  • Studying the earthquake geology of the Chilik-Chon Kemin Fault Zone in Kazakhstan

    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…

  • New papers on paleoseismology and active tectonics (August 2016)

    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.

  • Some great photo collections from the PATA Days 2016 in Colorado

    My dear colleagues Neta Wechsler, Stefano Pucci, and Oxana Lunina took some amazing photos during the PATA Days in Crestone, Colorado. Even better, they allowed me to distribute the links to their collections:

    Do you also have some photos that you’d like to share? Please feel free to link to your album in the comments section or drop me a mail.

  • Guest blog by Javier Escartín (IPGP) & Frédérique Leclerc (EOS): Studying coseismic deformation along submarine faults

    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.

  • New papers on paleoseismology, tsunami, and active tectonics (July 2016)

    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.

  • Open position: PostDoc on seismic hazard characterization & mitigation, Aix-en-Provence

    The CEREGE laboratory in Aix-en-Provence (France) look for a PostDoc in the field of seismic hazard and/or earthquake geology. The position is in the framework of the RISKMED OT MED funded project “ Natural risks in the Mediterranean: Hazard, vulnerability, perception and management”.

    Deadline for application is 4 July.

    Tasks:

    • Organisation and implementation of field surveys in Italy and Turkey in collaboration with local colleagues.
    • Review and compile existing data, and acquire new data to better understand the frequency and dynamics of large earthquakes in Central Italy and western Turkey through surface observations and paleoseismological reconstruction over a range of different temporal and spatial scales.
    • Convert all data into an open database.
    • Analyze and interpret all data with respect to existing scaling laws and in terms of seismic hazard.
    • Produce with social scientists engaged in the project (geographers and psychologists) comprehensible scientific information to public and territorial managers as the basis for recommended preparedness and mitigation actions.
    • Participate to a participatory process and to focus groups concerning risk mitigation strategies (science communication, risk communication, public outreach) in targeted areas.

  • Open position: Postdoctoral Research Assistant in Active Tectonics, Univ. Oxford

    The University of Oxford is looking for a PostDoc research assistant under the direction of Professor Richard Walker and Professor Philip England to work on active tectonics in China. The focus is on the Hexi corridor and the Qilian Shan of Gansu. Deadline for application is 15 July 2016.

    Tasks include:

    • Detailed mapping of palaeo-earthquake ruptures
    • Construction of slip distributions from individual earthquakes
    • Selection of sites for long-term slip-rate determination using field investigations, high-resolution satellite imagery and digital topography
    • Planning and carrying out fieldwork to verify remote-sensing observations, to collect samples for dating, and to excavate and interpret palaeo-seismic trenches

  • Those were the PATA Days 2016 in Crestone, CO

     

    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. more

  • New papers on paleoseismology, tsunami, and active tectonics (June 2016)

    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!
