Surface faulting is commonly observed after moderate to strong (Mw > 6.0) earthquakes. Beside primary faulting along the seismogenic structure, distributed faulting (DF) may occur in the vicinity of the principal faulting (ANSI/ANS-2.30, 2015). DF may impact wide areas and its forecasting is particularly relevant for the design of critical or distributive infrastructures (e.g., nuclear power plants). DF assessment is currently pursued through probabilistic fault displacement hazard assessment (PFDHA): in this approach, the conditional probability of DF occurrence is computed as a function of magnitude and distance from the primary fault. Empirical regressions were obtained for the different tectonic styles, based on a limited number of case histories (e.g., Youngs et al., 2003 for normal faults). more

A new issue of Quaternary Perspectives, the INQUA newsletter edited by Lyudmila Shumilovskikh, is out now. QP 25(1) includes a great report by Neta Wechsler on the 2017 PATA Days in New Zealand, more info about the 2019 PATA Days to be held in Israel, and a report on the Int’l Field Trip “From 1997 to 2016: three destructive earthquakes along the Central Apennine fault system”, 19 – 22 July 2017, Italy. Allan Ashworth informs in his INQUA president’s report about the changes that lie ahead and the upcoming challenges in re-structuring INQUA. Plus, there are interesting news on other potentially earthquake-related groups and projects such as 1701P (Late Quaternary records of coastal inundation due to earth surface deformation, tsunami, and storms), PALSEA2, HOLSEA, and GEODUST. The current issue of Quaternary Perspectives can be downloaded here (PDF, 2.57 MB) and will soon be archived at the new INQUA website (check it out!).

If you are looking for affordable accommodation for PATA Days 2018, you may want to consider staying at the University campground, one of the two venues of the meeting. Please note that the number of houses available is limited, so it is advisable to book as early as possible. Find all information you need here:

The following email from the organisers of the 6th Colloquium on historical EQs & paleoseismology has some important news for those intending to join the meeting in Han-sur-Lesse in October:

Dear Colleague,

If you intend to participate to the “Sixth International Colloquium on Historical earthquakes & paleoseismology studies: their contribution to the knowledge of the long-term seismic activity and to seismic hazard assessment” that will be held from 24 to 26 October 2018 in Han-sur-Lesse (Belgium), we encourage you to register as soon as possible, because the pre-booked hotel rooms are limited to 40 at the hotel “Grenier des Grottes”, one of the few place to lodge in Han. This reservation is valid up to one month before the meeting, after that, the rooms will be available for tourists!

Please find the registration form, the call for abstracts and general information at the following address:

For additional information, please contact Thierry Camelbeeck: thierry.camelbeeck@oma.be

Best regards

It looks like April/May is high season for publishing – or is it that all those papers you submitted right before Christmas are now making it through review…? Anyway, we have a lot of exciting stuff this month, including a number of studies on the Med, on Central Asia, and on New Zealand. Plus fault physics, subduction zones, glacial seismicity in N Europe, Malawi, and much more.

Enjoy reading and let us know in case we’ve missed something. more

A large landslide occurred in SE Kazakhstan near the town of Saty (Саты), TengriNews.kz reports. The slide is about 900 m wide, 1700 m long, and has an estimated volume of ~50,000,000 m³.   Apparently nobody was harmed, but the now slow-moving landslide mass approaches Kolsai river. The road to Kolsai lake (a landslide lake) is blocked. Images and videos from the area show what may be a thick layer of loess that moved downhill after heavy rain. more

This month’s list of active tectonics papers contains a lot of tsunami and landslide studies, and some great stuff from Asia. Plus, New Zealand is in the focus of a number of papers. I guess it’s just about the right time period after the Kaikōura EQ to have a paper written and through review…

Enjoy reading and happy Easter!

The 1988 Spitak Earthquake with a magnitude of M_S6.8 took the life of thousands of people and caused widespread devastation in Armenia. It also ruptured the surface and is one of the best-studied seismic events in the entire Caucasus region. 30 years after the catastrophe, an conference will be held in Yerevan, Armenia, from 3-7 December: “30 years after Spitak Earthquake: Experience and Perspectives“. The meeting will also include a field trip to the epicentral area. Full conference fee is USD 200. Download the flyer here (pdf, 655 KB). The form for the expression of interest is here (docx, 19 KB). more

A month has passed and plenty of new papers have been published. This time we have a number of contributions on the tectonics of Italy and Asia, news about seismic hazards maps, and some great earthquake physics. Enjoy the latest papers on paleoseismology, tsunami, and active tectonics: more
