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

Europe’s biggest geoscience conference, the EGU General Assembly 2014, is approaching! Held in Vienna, Austria since about ten years by the European Geoscience Union, it brings together loads and loads of scientists from even more scientific fields. It’s great to present your work to your scientific community (because it’s likely they are there) but it might be even more suitable to meet new people, who give you helpful or even challenging input for your work! more

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. more

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

The 2nd European Conference on Earthquake Engineering and Seismology (2ECEES) will take place from 24-29 August, 2014 in Istanbul, Turkey. The meeting is a a joint event of the European Association of Earthquake Engineering (EAEE) and the European Seismological Commission (ESC). There will be a session on Paleoseismology: more
