“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

I still try to catch up with all the amazing new stories on earthquakes, tsunamis and paleoseismology that made it to the media last week. Here is #2 on a reviewed tsunami database for Australia.  more

A lot of interesting stories on earthquakes, tsunamis and paleoseismology made it to the media last week – no wonder as the EGU2014 and the SSA meeting took place at the same time. I will try to catch up and I start with tsunami hazard in Israel:

What a week. I’ve seen loads and loads of interesting posters and met great people. more

After a very nice Opening Reception yesterday, we today shift from “pure networking” to scientific talks and posters. The Earthquake Cycle session started off with highly interesting research on active tectonics in Central Asia and on the Chi-Chi and New Madrid EQs.

As we are often use geodata and analyse, store them or visualize them using a GIS we depend somehow on the person on the other side to understand how a GIS functions or how to use the GIS. A webmap- like the well know google maps- is therefore an easy way to communicate your data and results. But creating a webmap is not always a funny thing to do as we are more geoscientists than programmers. QGIS2leaf for QGIS is a great plugin for creating a basic webmap. more

The San Andreas Fault Observatory at Depth (SAFOD) was one of the most ambitious (and expensive) experiments in the history of active fault research. A borehole was drilled through the San Andreas Fault, 3.2 km deep and 1.8 km in horizontal direction. The borehole was equipped with a number of instruments in order to get data from right where the earthquakes occur, but most of the instruments failed already in 2008 due to the extreme conditions. While analyses of the drill core resulted in some great scientific achievements and enhanced our understanding of fault zones, almost no one seems to have much interest in the in-situ instruments. Or let’s say, no one can pay the necessary amount for re-equipping the hole, millions of dollars…  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.

Dear friends and colleagues,

We are all looking forward to the 5th PATA Days meeting! Don’t forget to register for this conference in Busan, Korea. The meeting will take place from 21-27 September and all information can be found at http://www.pata-days.org.

The second circular is out now, please download the pdf here (PDF, 800 kb). more

If you can’t find funding for attending the 5th Pata-Days in Busan, Korea, there is still the chance to see and present some good research on earthquake geology in Germany. There will be a session Active Tectonics and Earthquake Geology at the GeoFrankfurt 2014 meeting in late September, so don’t miss the deadline:

Dear colleagues,

Within the frame of the conference GeoFrankfurt 2014 we are organizing a session on Active Tectonics and Earthquake Geology (B13). The conference is held at the Goethe Universität at Frankfurt, 21-24 September 2014.

Conveners: Ioannis Koukouvelas, Kurt Decker and Klaus Reicherter

Deadline for abstract submission: 25 April, 2014 more
