The Tien Shan takes up about 20 mm/yr of N-S shortening as a result of the India-Eurasia convergence. Recent paleoseismological studies have shown that the shortening is accommodated by a large number of faults, whose slip rates are relatively low. Although the historical earthquake catalogues only reach back a few hundred years, we know that the Tien Shan has seen some of the strongest intracontinetal quakes world-wide with magnitudes exceeding M8. Paleoseismological studies have revealed a large number of surface-rupturing earthquakes, too. But the question is: Do all these known faults rupture in strong earthquakes? In a recent paper, my colleagues and I argue that there is at least one major fault in the Northern Tien Shan that is creeping (Mackenzie et al., 2018). more

On Thursday 28^th June, I had the opportunity, together with over 40 students and Early Career Researchers, to attend the full-day summer school organized during the 9^th PATA Days Congress in Possidi, Greece.

Gotha speakers gave short lectures on a variety of topics; well, it’s quite strange realizing that behind a book cover or a long list of papers you’ve read there’s a real person with a face, 2 hands and 2 eyes… but that’s what happened to me.

Location, location, location

As geoscientists, we all know the importance of a proper location… the Possidi Holiday Resort is just 20 m from the beach! Even the storm Hera did not prevent us to go for a swim.

The summer school

1. The first lecturer was Klaus Reicherter, dealing with tsunamis in the Mediterranean and in Greece and highlighting the inherently multidisciplinary nature of such a research.
2. Tom Rockwell focused on strike-slip fault with worldwide examples – S. Andreas, North Anatolian, Great Sumatra and Dead Sea Faults – and field-based results.
3. Jim McCalpin spoke about the use of paleoseismology in seismic hazard assessment, giving us a bucket of real-life examples, experiences, good (and less good) practices. And I learned that when building a logic tree, a 5% probability is not denied to (almost) everybody.
4. Shmulik Marco showed on- and off-fault archaeoseismological evidences and soft-sediment deformations along the Dead Sea Fault. Plus (in my opinion) the best tip of the day: keep good relations with archaeologists, you never know what they will discover under the dirt.
5. Then, Spyros Pavlides dealt with active faulting in multi-fractured seismic areas, and specifically the Aegean region. Just in case you are wondering if there’s something simple there, ehm… no, you should consider multiple tectonic phases, inherited structures, the presence of normal faulting, subduction zones and volcanic activity all together.
6. We definitely changed perspective with Manuel Sintubin, speaking about earthquake risk communication and the need to move from a risk message model toward a risk dialogue model; this is a super-important topic not always addressed in the proper way, with possible huge consequences.
7. Ioannis Papanikolaou spoke about the seismic landscape, extraction of slip rates and fault specific SHA with tens of examples from Greece and Italy and useful tips on advantages and disadvantages of each methodological approach.
8. Finally, Georgios Syrides gave a lecture on sea level change indicators. Well, I’m very ignorant on this because simply it’s not my bag, so I learned lots of things (bonus: super-cool photos!).

Here’s the PATA team! (yes, I’m quite mad with football and the World Cup was ongoing…)

“He who knows only his own side of the case knows little of that” – John Stuart Mill, On Liberty, 1859

I saw top scientists jump on their seats when other top scientists called “small” a M 6 or “moderate” a M > 7 earthquake. Or when a trench revealing 5 events was called a “short record”. We all have different perspectives, opinions and experiences. And with “we” I mean all of us, from top scientists down to undergraduate students. I think it’s a richness and we should take care of it.

Final remarks: thanks!

The success of the summer school and the whole 9^th PATA Days meeting would not have been possible without the contribution and efforts of the Thessaloniki University staff. A big thank to all of you and see you in the next PATA meeting!

The conference “30 years after the Spitak Earthquake: Experience and Perspectives” will be held in Armenia from 3-7 December, 2018. Abstract deadline is 15 September. The first circular has just been released, download the PDF here. The abstract template in MS Word format is available here.

A lot of interesting papers have been published in the past month, including studies on recent moderate to strong earthquakes, geomorphology, fault physics, and some classic paleoseismology. These are the latest articles on paleoseismology and active tectonics – enjoy! more

NH021: Interdisciplinary Tsunami Science

Session ID: 46945

Tsunamis are one of the most devastating natural disasters, with the potential for inflicting huge damage along wide stretches of coastal areas. Recent tsunami events have demonstrated that the tsunami risk has grown tremendously since the last ocean-wide tsunami of 1964, primarily due to the expansion of coastal development and the maritime communities. Tsunami science has become one of the most inter-disciplinary research areas. Social science, applied mathematics, engineering, and geology are as important to tsunami research as traditional seismology and oceanography. This session provides a broad forum for cross-disciplinary studies and invites contributions from all areas of tsunami science including: fundamental and basic research; forecast and warning procedures for current and future events; investigation of geologic records and hindcasting of past events; response, mitigation, and recovery strategies; tsunami observations; socio-economic impacts; and hazard and risk studies from tsunamis generated by earthquakes, landslides, volcanic eruptions, meteorological phenomena, and meteorite impacts.
