  • Special Issue in Applied Sciences: “The Contribution of Geology and Geomatics to Seismic Hazard and Earthquake Engineering”

    Our colleagues Javier Elez and Jorge L. Giner-Robles invite contributions to a Special Issue in the journal Applied Sciences:

    In recent decades, a prominent body of knowledge related to the geology of the earthquakes has provided new insights into seismic phenomena. The study of geology of present earthquakes allows a better understanding of the whole set of natural processes involved. The study of events from the past allows providing more comprehensive data within the temporal range (recurrence periods) of the seismic cycle and therefore completing the seismic catalogues and incorporating long-term data into seismic hazard assessment. The introduction of geological analysis of earthquakes, mainly based on the application of the Environmental Seismic Intensity Scale (ESI-07), also allows the parameterization of environmental earthquake effects and the emergence of multiple modeling procedures to assess intensity, hazard, risk, emergency scenarios, etc., most of them based on the application of GIS technologies.

    The objective of this Special Issue on “The Contribution of Geology and Geomatics to Seismic Hazard and Earthquake Engineering” is to provide the latest advances, uses, and case studies related to the multiple applications of geological analysis of earthquakes.

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

    A continuous flow of images from the New Zealand earthquake reaches the earthquake geology community, and we’re probably all amazed by the coseismic offsets and other earthquake effects. However, the flow of papers on paleoseismology, tsunami, and active tectonics also does not stop and here is my digest for December. Enjoy reading!

  • Earthquakes in Italy: Field photos by Paolo Galli

    Our colleague Paolo Galli is in the epicentral area of the M6.6 Italy earthquake and he sent us some amazing images. I’ll just reproduce them here without further comment, they speak for themselves. Captions by Paolo. Thanks a lot Paolo, and stay safe! more

  • 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…
    Enjoy!  more

  • 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.

  • 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 in the Tien Shan

    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).
