New papers on Paleoseismology and Geoethics

Several new studies have been published recently on old earthquakes and their geological footprint – time to list them and to recommend reading. Additionally, today’s paper digest also lists several articles which are not about paleoseismology, but geoethics. These papers were published in a special volume of GSL. They cover subjects that many paleoseismologists will have dealt with in the past or are likely to deal with in the future  – seismic risk perception, science communication, public outreach, and communicating uncertainties. One paper is dedicated to the L’Aquila trial. I find it very telling that this issue is not open access. Obviously, strengthening “public trust in geosciences” has still a long way to go…

Here are the latest papers:

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.

New papers on paleoseismology, active tectonics and tsunami research

Pissia Fault scarp

Several new papers deal with paleoseismology and active tectonics studies. Wiatr et al. used terrestrial LiDAR to analyse limestone bedrock scarps, Hornblow et al. investigated the Darfield earthquake source in NZ. Sarikaya et al. present new data on offset alluvial fans in Central Turkey; Xu et al. present geological data on two historical seismic events in Tibet. Tectonic morphology is used by Barcelona et al. in NW Argentina. Mathew et al. use remote sensing data to analyze coseismic deformation in China. Ed Garrett and colleagues present data on 1000 years of megathrust quakes in Chile, and Bemis et al. have an interesting article on UAVs and paleoseismology.

Call for papers: Special Issue of the International Journal of Earth Science on Eastern Mediterranean Tectonics

The GeoFrankfurt conference took place a few days ago. Due to the large amount of work presented on Eastern Mediterranean Tectonics, a special issue on this topic will be published in the International Journal of Earth Sciences (former Geologische Rundschau). Paris Xypolias allowed me to circulate the call for papers: Continue reading “Call for papers: Special Issue of the International Journal of Earth Science on Eastern Mediterranean Tectonics”

First paper on the earthquake environmental effects of the 2014 Cephalonia (Greece) M6.0 quakes

On 26 January and 3 February, 2014, two strong and shallow strike-slip earthquakes of magnitude 6+ occured beneath the island of Cephalonia in Western Greece. Both events caused intense damage to buildings and infrastructure. A team of Greek geologists mapped earthquake environmental effects (EEE) such as liquefaction, road failures, rock falls, small/medium size landslides and stonewall failures. The results are now published in a paper in Tectonophysics. Continue reading “First paper on the earthquake environmental effects of the 2014 Cephalonia (Greece) M6.0 quakes”

A Mw6.9 earthquake in the Aegean Sea

Today (2014-05-24) on 09:25 UTC an earthquake with magnitude MW6.9 occurred in the NE Aegean Sea. The EMSC reports a depth of 27 km (USGS: 10 km). The quake had a (right-lateral) strike-slip mechanism and was felt as far away as Athens, Istanbul, and Sofia. More than 200 people were injured, most of them only lightly, and moderate damage to dozens of houses has been reported. The earthquake occurred on the (S)Western part of the North Anatolian Fault in the Samos Basin and was among the strongest events that have ever been recorded at that segment.

Crete and mainland Greece Fieldwork, March 2014

Uplifted algal rims at Sougia.

During the month of March 2014, Sascha and I along with Tobi and Lauretta (BSc students from RWTH University) were in Greece for fieldwork. The fieldwork campaign started on the island of Crete; our institute at RWTH Aachen has a joint project with Mainz University to carry out paleotsunami investigations on the island. The western part of Crete was uplifted by approximately 9 m during the 21st July AD 365 earthquake and also hit by the associated tsunami. Due to the strong seismic and highly tsunamigenic activity of the nearby Hellenic Trench, it is suggested that numerous earlier tsunamis have also struck the island.

Invited talk at RWTH Aachen University: Seismic Environmental Effects triggered by the January and February 2014 Cephalonia Earthquakes

Aachen

On Monday, 31 March, our colleague and friend George Papathanassiou from Aristotle University of Thessaloniki will give an invited talk about Seismic Environmental Effects triggered by the January and February 2014 Cephalonia Earthquakes. The presentation will start 2:00 pm at RWTH Aachen University, Lochnerstr. 4-20, 52064 Aachen, room 217. Please download the flyer here, guests are welcome.

Preliminary report on the earthquake environmental effects triggered by the Cephalonia quakes

A team of geologists mapped the earthquake environmental effects (EEEs) of the two M6+ events that occurred at the Greek Island of Cephalonia on 26 January and 3 February, 2014. G. Papathanassiou, A. Ganas, S. Valkaniotis, M. Papanikolaou and S. Pavlides participated in these field campaigns. George Papathanassiou sent me the preliminary report today. The team found widespread evidence for “liquefaction, road-fill failures, rock falls, small landslides and stonewall failures“.
