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: more

On 24 September, 2013, a magnitude 7.7 earthquake occurred in Balochistan, Pakistan. The quake caused intense ground motions and had dramatic consequences – hundreds of people died, and more than 100,000 lost their homes. A secondary effect which caught much attention in the international media was the birth of an island off the Pakistani coast – Zalzala Jazeera or Earthquake Island. Another effect which went almost completely unnoticed was a small tsunami in the Arabian Sea. The tsunami reached wave heights of around 1 m at the Omani coast. In a paper which was recently published in Geology, my colleagues and me document the tsunami effects in Oman. We conclude on a submarine slide off Pakistan as the likely trigger mechanism.

A good number of interesting papers has been published during the last months, related to active tectonics, paleoseismology and tsunami research. Study sites include Oman, Italy, New Zealand, California, Cascadia, Scotia Sea, and Central Asia. Enjoy reading and tell me, if you miss some publications here!

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
