  • Earthquake Geology sessions at the 16 World Conference on Earthquake Engineering, Chile, 2017

    The 16 World Conference on Earthquake Engineering will be held from 9-13 January, 2017, in Santiago de Chile. Note that the deadline for short abstracts submission is 23 November, 2015! Abstracts can be submitted via this link.

    This meeting comes with a number of sessions which are interesting for earthquake geologists, paleoseismologists and those of us who deal with seismic hazard assessments. Among them: more

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

    I’ve spent several weeks in Eastern Kazakhstan this summer for paleoseismological field work. During the first part of this trip we looked at some thrust and strike-slip faults in the Ili Basin and the Saty area. The second part was almost entirely devoted to study the Dzhungarian Fault. I’ll blog about this second part later. Eleanor, David, Austin and me were the UK representatives in our team. We were so lucky to have Kanatbek from Kyrgyzstan and Aydin from Kazakhstan with us. They did not only lead us to all the interesting places and helped us to understand the geology and the tectonics, but they also did a fanatastic job organizing the field trip and dealing with the local surprises, which as you know happen in basically every field trip.

    Our first study site was located at the northern boundary of the Ili Basin, where we did some work last year already. more

  • 14th International Conference of the Geological Society of Greece – deadline 30 Sept.

    Greece is a Disneyland for neotectonics and active faulting research. Some of the most important findings in earthquake science have been achieved in Greece, its historical catalogue is one of the longest on Earth, and paleoseismology, archaeoseismology & tsunami studies are abundant. These are many good reasons to consider registration for the 14th Int’l Conference of the Geological Society of Greece (Thessaloniki, May 25-27, 2016), especially since the programme is full of earthquake science stuff. The deadline for submitting papers is September 30.

  • ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue”

    Earthquake Environmental Effects (EEE) have proven to be valuable for describing past earthquakes and their geological imprints. The ESI2007 is a relatively new intensity scale dedicated to such effects, but also integrating traditional macroseismic scales. Examples of ESI2007 intensities assigned to large earthquakes are being collected in the EEE web catalogue hosted by the ISPRA and ESI2007-related work is conducted in the framework of INQUA.

    Another milestone now has been achieved with the ISPRA volume “Earthquake Environmental Effect for seismic hazard assessment: the ESI intensity scale and the EEE Catalogue”. This book is now available online here. It contains updates on the ESI2007, examples of applications, documentation of the EEE Android App, a huge reference list and, most importantly, the ESI2007 description in ten languages: more

  • This was the Fucino15 meeting – part I

    Phew, this was an intense week and a great one too! The Fucino15 meeting on paleoseismology, active tectonics and archaeoseismology is over and hopefully everyone safely arrived back home. Here’s a brief report on some of the science that happened at the meeting. Since we had ~50 oral presentations, only an overview is possible here. In the following days I’ll add more details about the field trips. A big thank you to the Italian organizing team who did an amazing job – grazie mille! more

  • New paleoseismology papers

    It’s been a while since the last update on paleoseismology literature. BSSA’s latest issue has some interesting studies that you should check, and there’s even more to discover. Also, there is some new work on (paleo-)tsunamis and historic large earthquakes. If you feel that important new papers are missing, drop us a mail! more

  • Paleoseismology at EGU2015

    The EGU2015 will be held from 12 – 17 April in Vienna, but the abstract deadline is much closer: Day after tomorrow, 7 January! So if you haven’t already done so, it’s time to have a look at paleoseismology-related sessions at EGU: more

  • New report on the Napa Earthquake available, update on amount of afterslip

    Our colleague Tim Dawson from the California Geological Survey (CGS) pointed me to this website, where reports and data on the Napa Earthquake of 24 August, 2014, are collected. There is a new document available for download, the EERI report at the top of the page, which adds some previously unpublished information, especially on the observed afterslip. Tim writes that “afterslip along the central 6-7 km of the rupture is about 35 cm (whereas it was initially only about 20 cm the day of the earthquake).” The afterslip seems to be still ongoing and is monitored with InSAR. more

  • 1st circular out now for the 6th INQUA paleoseismology workshop in Fucino, Italy, 19-24 April 2015

    The 6th INQUA workshop on Active Tectonics, Paleoseismology and Archaeoseismology will be held from 19-24 April, 2015, in Pescina, Fucino Basin, Italy.

    We will remember the centenary of the 1915 M7 Fucino earthquake, that was one of the largest and most devastating earthquakes ever occurred in Central Italy.

  • 3He dating of rockfalls helps to distinguish between proximal and distal paleo-earthquakes in Christchurch, NZ

    The 2011 Christchurch earthquake series had severe consequences and surprised scientists for many reasons. Ground motions were extremely strong despite the relative moderate magnitudes of the quakes (MW 5.3-7.1). The events happened on a system of hitherto unknown faults, some of which are located directly below Christchurch. Earthquake environmental effects (EEE), especially liquefaction, were intense and widespread. It turned out that subsequent quakes reactivated the same feeder dikes of sand blows, showing that saturated sediments are susceptible of liquefaction no matter if they had been liquefied recently (also see the paper of Quigley et al. (2013) on the liquefaction effects). Another stunning lesson was the occurrence of intense rockfall in the vicinity of Christchurch. In a recently published study, Mackey and Quigley (2014) dated rockfall boulders with 3He and show that they allow to estimate the recurrence intervall of local seismic events like the 2011 series. This works is a very interesting way to use EEE for paleo-earthquake studies. more
