  • This was my field work on active faults in Kazakhstan 2015 (pt. II)

    The first part of my report on the field work that I did in Kazakhstan this year focussed on the stuff we had done in the South. Here is part II which is all about the Dzhungarian Fault. You’ve never heard about this fault? That’s easily possible. There are only very few papers that deal with this fault. In the 1960s Soviet geologist V.S. Voytovich published results from extensive field work on this fault (Voytovich, 1965; 1969). 40-50 years later a few studies on geodesy and geodynamics covered the broader study area and Shen et al. (2003) did some work in the Chinese part of the fault, but it took until 2013 before Campbell et al. revisited the Kazakh side and came up with new field data. They focussed on the tectonic geomorphology of this structure and determined a slip rate. Given this little amount of research done one would assume that the fault is not very large and of minor importance, but the opposite is true. The fault is around 300 km long in its Kazakh section and probably twice as long in total! more

  • What’s up? The Friday links (82)

    Today is Friday and here are your links on human-caused earthquakes, induced aseismic slip, typesetting costs, flash flood video footage, and more!

  • This was the Fucino15 meeting – part II

    I blogged about the scientific sessions at the Fucino15 meeting last week, here’s my report about the pre- and post-meeting field trips. The pre-meeting field trip was held in Rome, where we explored the archaeological and historical evidence for earthquake damage in the Eternal City. After the conference we followed the traces of the 1915 Fucino earthquake and then finally visited L’Aquila. This blog covers Rome and the geological field trips, a special on L’Aquila will follow later. more

  • Tectonics from above – RAS discussion meeting

    Last Friday the RAS held a discussion meeting on Tectonics from Above: Recent Advances in the Use of High-resolution Topography and Imagery in London. Almost the entire Cambridge Tectonics Group went there and I absolutely enjoyed the meeting and the discussion with friends and colleagues mainly from the UK and from France. The speakers reported on open-source software for producing high-res DEMs, advances in aerial and satellite imagery, new techniques in remote sensing, and latest developments in fault/offset mapping. The meeting was supported by NERC, COMET+ and LICS. more

  • What’s up? The Friday links (60)

    A long year ago, the last Friday links were published, a section I always liked and waited for during food coma or processing times. Christoph managed to find intriguing bits and pieces from the digital world of geosciences week after week. And now it’s me (and maybe with a little help from my friends), trying not only to follow-up but also to keep you updated and to keep the geoblogosphere interconnected. What a task! I’m already loving it.

  • Deform2015, thematic school about crustal deformation and earthquakes

    The Deform2015 school on Active Deformation, Faults and Earthquakes from Measurements to Models will be held in Southern France from 7-13 February, 2015.
    Over the past years, considerable advances have been made in observing crustal deformation at scales of seconds to thousands of years.
    However, a unified view of the earthquake cycle is still missing. The thematic school aims at bringing together students and scientists
    working on different aspects of active faulting and earthquake processes. This school will provide a state-of-the-art view of the technics used to study active deformation as well as a perspective on the current models integrating the growing corpus of available data.

  • New paleoseismology papers

    Besides the two special issues on tsunamis and paleoearthquakes that I’ve already blogged about, some more interesting papers on paleoseismology have recently been published. They deal with paleoseismology of the North Anatolian Fault, with tectonic geomorphology of S Spain, and with the ESI scale applied on a quake in Kashmir. more

  • What’s up? The Friday links (7)

    Albini made forensic studies on the origin of “fake” earthquakes in historical catalogues and shows  in her new paper how the 1272 earthquake “happens”. I like the paper as it provides some insights in the structure of earthquake catalogues and their interactions. It shows how historical and paleoseismological studies may complement each other.
