The new open access journal Frontiers in Earth Sciences recently appeared. Its first published article in the Structural Geology and Tectonics section is an overview piece by Chief Editor Agust Gudmundsson about Great challenges in structural geology and tectonics. The article provides a nice round-up of some basic questions in tectonics that are still not well enough understood and which definitely need to be addressed in the (near) future. It starts from questions which sound easy to be answered (How many tectonic plates are there?), but actually aren’t. more
Elsevier has put together a number of papers that were published in its various journals on the Wenchuan 2008 earthquake and made a “Virtual Special Issue” out of that. So, the good news is not about new papers on that quake (some work was already published in 2011), but rather that this selection of papers is free until 14 February 2014 via this link: http://www.journals.elsevier.com/tectonophysics/virtual-special-issues/virtual-special-issue-on-the-2008-wenchuan-earthquake/
That’s not open access as we like it, but at least a step in the right direction.
Researchers have discovered the remains of a royal wine cellar at the Tel Kabri archaeological site in Northern Israel. They found ~40 crushed jars, which equals about 3,000 bottles, and they were able to analyse the chemistry of the organic traces from the jars. It’s clear that they contained red and white wine, which was spiced with “honey, mint, cinnamon bark, juniper berries and resins” as it was common 1,700 BC. The fact that all jars contained wine with the same chemical fingerprint led the researchers to conclude that the wine had a high quality and was, therefore, likely part of the Canaan palace’ reserve. This is already a pretty good story, but the New York Times also mentiones that “the cellar was destroyed 3,600 years ago in some violent event, perhaps an earthquake“. Yee-haw, archeoseismology! Here we go! But wait – what do we actually know about the earthquake? more
The new issue of Seismological Research Letters has been published now and it contains a lot of articles for those liking old earthquakes. Some topics might sound familiar to you when you attended the PATA days conference as the authors presented parts of their work.
I have selected a few papers that are especially interesting to the paleoseismology community. They are about the use of Google StreetView for assessing macroseismic damage (Hinzen, 2013), archeoseismology in the Levant (Alfonsi et al. 2013), Earthquake rotated objects caused by the Emilia Romana earthquake – a fascinating EAE! (Cucci and Tertoulliani, 2013), a strong historical earthquake in Italy that likely did not happen at all (Camassi and Castelli, 2013) and new data on historical earthquakes in the Himalayan (Rajendran et al, 2013). Also, I added a paper on archaeoseismological investigations in northern Sicily that was published recently in Quaternary International (Bottari et al, 2013). Spend the rainy autumn evenings with a good read!

Dear colleagues and friends,
thank you very much for making the PATA Days 2013 such a great event! I hope you all had a safe trip back home or some more nice days with better weather. The abstract volume of the PATA Days is now available online. Currently, you can only download the entire volume, we will upload the single files into a sub-directory later.

Recent archaeoseismological studies have provided us with spectacular examples of skeletons as earthquake archaeological effects. Cases include the Neolithic skeletons of Tell es-Sultan, ancient Jericho (one of them beheaded by a fracture crossing the site!) published by Alfonsi et al. in SRL (2012) and the skeletons smashed by building collapse reported by Berberian et al. in JAS (2012).
To this list should now be added the case of Lajia (Guanting Basin, central China), where a team of Chinese researchers uncovered a series of skeletons buried under a thick layer of clay interpreted as the result of an enormous, earthquake-related mudflow c. 3950 cal BP. more
A new article on archaeoseismology appeared yesterday in Geoarchaeology’s Early View section. In this paper, Karabacak and colleagues present archaeoseismological evidence in the Roman stadium of ancient Kibyra (southwest Turkey). Earthquake archaeological damage includes surface faulting, systematically collapsed columns, dilated and collapsed walls, as well as rotated and displaced blocks. Their study suggests that a previously unknown seismic event (Io = VIII-IX) may have struck this region of Turkey around the 10-11 th century AD. more
A new paper by Esposito et al. has been published in Springer’s Landslide Science and Practice that will help to better constrain intensities on the ESI scale. Landslides induced by twelve moderate to strong earthquakes events during the last 300 yrs have been analyzed. The authors calculated distance vs. magnitude and distance vs. ESI epicentral intensity relationships, similar to the famous correlations by Keefer (1984). more
The latest issue of the Seismological Research Letters (SRL) has at least three papers dealing with topics interesting for paleoseismologists.
Hinzen et al. studied the rotation of objects (e.g., monuments) during the L’Aquila earthquake of 2009. They scanned the rotated objects with a high-res laser scanner, built discrete-element-models from the data and simulated the shaking necessary to cause the deformation. The results help to better estimate earthquake parameters from earthquake archaeological effects (EAEs).

A new paper in Tectonophysics deals with the use of terrestrial LiDAR for identifying the slip vectors on fault planes. Thomas Wiatr, Klaus Reicherter, Ioannis Papanikolaou, Tomás Fernandez-Steeger and Jack Mason collected and processed data from Crete island (Greece), where they scanned the scarp of the Spili Fault. They imaged numerous kinematic (slip direction) indicators like slickensides with this relatively new technique. The t-LiDAR data were then compared to traditional compass measurements in order to get an idea about the derivation betwen old-school measurements and high-tech methods. more
