Intraplate earthquakes are those that occur far away from plate boundaries in what is often also referred to as slowly deforming regions or stable continental regions (SCR). Seismicity there is comparably low and earthquake recurrence intervals can easily exceed thousands of years for individual faults. However, intraplate quakes do account for a significant number of earthquake fatalities and killed more people than those that happened at plate boundaries during the last 100 years (England & Jackson , 2011). A new book has been published a few days ago, dedicated to summarizing our knowledge of these seismic events. more
It’s not been long since I’ve listed some recent paleoseismology papers, but it seems like it’s publishing season. So here is more stuff to read during the holidays… more
A new book on paleoseismology, archaeoseismology and earthquakes on the Iranian Plateau has been published in the Developments in Earth Surface Processes series. Volume 17 is dedicated to Earthquakes and Coseismic Surface Faulting on the Iranian Plateau A Historical, Social and Physical Approach, and it is authored by Manuel Berberian. The book not only covers physical processes related to earthquakes in Iran like coseismic offsets, archaeoseismological effects, and geomorphological evidence, but its first part is all about Earthquake Hazard Warning in Oral Tradition and Literature on the Iranian Plateau. The volume comes with a foreword by Robert Yeats and Roger Bilham. Table of contents:

The latest issue of BSSA features a good number of studies on paleoseismology and earthquake geology, and some more papers have recently been published elsewhere which will be interesting for people working on old earthquakes and tectonics.
Here’s my digest, enjoy reading! more
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. more
An interesting new project aims on a better understanding of ancient earthquakes in Europe. ArMedEa – Archaeology of the Medieval Earthquakes in Europe (1000-1550 AD) is dedicated to increase our knowledge of medieval seismic events. The 2-years project based at Durham University will focus on archaeological information on quakes, tsunamis and earthquake-induced mass movements. ArMedEa is run by Paolo Forlin (supervised by Chris Gerrard and Dave Petley). The project has just started and already has its own blog. more
“Doggerland” refers to a drowned landscape located where the North Sea stretches today. Fishermen have found numerous archaeological artifacts when fishing between the coasts of UK and Denmark/Germany (more or less), which led to the idea that an ancient culture lived in this area when the sea level was lower some thousands of years ago. Archaeological studies and modelling confirmed this hypothesis (e.g., see Coles, 2000 or see this paper with a really cool title: White, 2006). Slowly rising sea levels and/or land subsidence forced our ancestors to move to higher grounds and to finally give up Doggerland at all around 8 ka ago. Jon Hill and his co-authors now added some more spice to this story. At the EGU they presented modelling data which imply that the Storegga tsunami over-ran the remaining islands, and that the end of Doggerland was sudden. more
Vanja Kastelic and Michele M. C. Carafa (INGV, L’Aquila, Italy) recently published an article in the Bollettino di Geofisica Teorica e Applicata (an international journal of Earth sciences) entitled “Earthquake rates inferred from active faults and geodynamics: the case of the External Dinarides.” This article covers the area affected by the earthquake of Ml 4.7 (Mw 4.6) occurred on April 22, 2014.
The same authors also wrote a brief seismotectonic report dealing with such an earthquake. They share the report with us under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

I added a couple of new papers to my literature collection last week. The studies deal with trenching in Iran and in China, tsunami research in Japan, Malta and Thailand, with archaeoseismology in Italy, and with seismic hazard of old oceanic lithosphere. Enjoy reading! more
At the end of last year, NHESS published a Special Issue on marine and lake paleoseismology. The volume 154 is an outcome of the ESF meeting Submarine Paleoseismology: The Offshore Search of Large Holocene Earthquakes that was held in
Austria in September, 2010. Guest editors are D. Pantosti, E. Gràcia, G. Lamarche, and H. Nelson. The Special Issue is open access and contains 16 research papers on all kinds of research on paleoseismology offshore. Some of the papers have been published as early as 2012, but others came out few weeks ago. more
