9:00 The second day started with a great keynote, Chris Scholz talked about earthquake triggering and fault synchronization with examples from California and Iceland.
09:45 Next great keynote: Clark Burchfiel on the Wenchuan EQ!

After the very successful 1st Workshop on Earthquake Archaeology and Paleoseismology held in the ancient roman site of Baelo Claudia (Spain, 2009), the INQUA Focus Group on Paleoseismology and Active Tectonics decided to elaborate a bi-annual calendar to support this joint initiative with the IGCP-567 “Earthquake Archaeology”. This second joint meeting moved to the eastern Mediterranean, a tectonically active setting within the Africa-Eurasia collision zone and located in the origins of the pioneer’s works on archaeoseismology. However, for the coming year 2012, at least a part of us will move also to the New World, where the 3rd INQUA-IGCP 567 international workshop will take place in Morelia, Mexico in November 2012. It is planned to proceed with the meeting, so we are thinking of Aachen, Germany, to be the host in 2013, possibly together with Louvain, Belgium.
A new paper published in Natural Hazards today discusses post-depositional changes of tsunamites. At sites in Thailand covered by sediments of the 2004 Sumatra tsunami, Szczuciński (2011) has documented significant changes in the deposits over the last seven years. Not only were the tsunamites altered, eroded or re-deposited by animals and seasonal rain, but also vanished in certain cases.
A new book with focus on paleoseismology has been published by GSA. Special Paper 479 – “Geological Criteria for Evaluating Seismicity Revisited: Forty Years of Paleoseismic Investigations and the Natural Record of Past Earthquakes” is edited by Franck A. Audemard M., Alessandro Maria Michetti and James P. McCalpin. Again, a lot of interesting reading stuff for your flight to Corinth…
Yesterday, a magnitude 5.8 earthquake happened near Mineral, Virginia in a depth of 6 km only (37.936°N, 77.933°W) with a thrust faulting mechanism. Media report that the quake was felt as far as Boston and even Canada to the north, but significantly less far away in southern direction. The US East Coast quakes are normally felt in a wide range, since the crust there is old, cold and dense which makes it easy for the seismic waves to propagate. Some damage occurred at the epicentral area, but apparently there were no fatalities. From the earthquake effects (Chimneys collapsed, walls cracked, some springs showed changes) and instrumental measurements an epicentral intensity of VII can be determined. more
Earthquake prediction again: The former president of India, Abdul Kalam, said earthquake prediction will be possible within 10 years. It would be great if he was right, but he isn’t. Why do people continue to say that? There are so many that “predict” earthquakes, and so many people relying on them. What a pity… more
Our new paper on lake Ohrid was published in the ZDGG: Reicherter, K., Hoffmann, N., Lindhorst, K., Krastel, S., Fernandez-Steeger, T.M., Grützner, C., Wiatr, T. 2011. Active basins and neotectonics: morphotectonics of the Lake Ohrid Basin (FYROM and Albania). Z. dt. Ges. Geowiss 162 (2), 217 -234. more
This week’s Friday links are almost entirely earthquake related.
On James’ Empty Blog you can find some scary but interesting videos from the Japan tsunami area.
The 3rd INQUA-IGCP567 international workshop on paleoseismology and archeoseismology will take place in Mexico in November 2012. It’s the 100th anniversary of the Acambay Earthquake.
The public version of the EEE Catalogue, a global catalogue of environmental effects induced by modern, historical and paleoearthquakes, is available at http://www.eeecatalog.sinanet.apat.it/terremoti/index.php. This public version has been developed on Google Earth and aims at providing basic information at earthquake, locality and site level, including the rupture zones (when available) and the local description of environmental effects, integrated by some imagery (photographs, stratigraphic logs, etc.). more
Cyprus explosion caused an M3.0 earthquake: On 11 July, a catastrophe took place in southern Cyprus. 2,000 tons of amunition confiscated from an Iranian ship on its way to Syria exploded. 13 people were killed and the military base and a neighbouring power plant were destroyed. Seismographs have registered the shock as an earthquake with magnitude ML3.0.
