  • 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!

  • Special Issue in Annals of Geophysics on the Amatrice earthquakes

    Annals of Geophysics has just published a special issue on the devastating Amatrice Earthquake series in Central Italy: Vol 59, Fast Track 5 (2016): The Amatrice seismic sequence: preliminary data and results.

    The special issue, edited by Marco Anzidei and Silvia Pondrelli, contains lots of field reports, first assessments, and plenty of primary data. Plus, it’s all OPEN ACCESS! more

  • Preliminary Map of Co-Seismic Landslides for the M 7.8 Kaikoura, New Zealand Earthquake

    The M7.8 Kaikoura Earthquake in New Zealand produced one of the most complex ruptures ever observed, involving many different faults. Earthquake environmental effects include up to 10 m offset at the Kekerengu Fault, secondary ruptures, a tsunami, coseismic uplift, landslides and rockfalls, liquefaction, and maybe even earthquake lights. Lots of blogs and websites provide coverage on this earthquake, e.g. Geonet, the Landslide Blog, and The Trembling Earth. Our colleagues from the Research Group on Earthquake Geology in Greece worked on the landslides that happened during the earthquake. George Papathanassiou sent me the link to their Preliminary Map of Co-Seismic Landslides for the M 7.8 Kaikoura, New Zealand Earthquake. more

  • 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

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

    A lot of new papers have been published on paleoseismology, earthquake geology, active tectonics and tsunamis last month. We have research on slowly deforming regions, on the active tectonics of Mexico, New Zealand, Armenia, and Iran, new data from the Kumamoto earthquake, plus some marine/coastal paleoseismology and tsunami studies. Enjoy reading!

  • Report on the coseismic effects of the 24 August 2016 Amatrice Earthquake

    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.

    Please cite the report as follows:

    • EMERGEO Working Group (2016). The 24 August 2016 Amatrice Earthquake: Coseismic Effects. doi: 10.5281/zenodo.61568

    The EMERGEO Working Group consists of Pucci S., De Martini P.M., Nappi R., Pantosti D., Civico R., Ricci T., Moro M., Cinti F., Brunori C.A., Di Naccio D., Sapia V., De Ritis R., Gori S., Falcucci E., Caciagli M., Pinzi S., Villani F., Gaudiosi G., Burrato P., Vannoli P., Kastelic V., Montone P., Carafa M., Patera A., Vallone R. (all INGV) and Saroli M., Lo Sardo L., Lancia M. (University of Cassino and southern Lazio).

    Thanks to Francesca Cinti for pointing me to this!

     

  • Video: Special Session on the Amatrice Earthquake at the 88º Congresso della Società Geologica Italiana, Naples, 7 September 2016

    A special session on the Amatrice Earthquake of 24 August in Italy was held at the Congress of the Geological Society of Italy (Naples, 7 September, 2016). A video of the entire session is now available online. Although the talks are in Italian, it is easy to understand and the slides tell the story.

  • 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.
