Now that the abstract submission deadline has passed you might be interested in somehow paleoseismicity-related sessions at the EGU2012. I decided to group the session by topic and my choice is absolutely based on personal interests. Sorry if I don’t mention every earthquake-related session.
The Geosciences Center at the National Autonomous University of Mexico invites applications for Assistant Professor/Researcher Position with expertise in Paleoseismology and Neotectonics. Applicants are required to have a PhD, basic knowledge of Spanish (no fluency is needed), and expertise in field-based Paleoseismology or closely related fields. Applicants with some experience in Landslides effects and evaluation are particularly encouraged.
Recently, scientists from Switzerland came up with the news that fractured bedrock might amplify earthquake shaking. The say they observed an increase by factor 10, which seems huge. I knew amplifying by sediment basins, but this is new to me.
100 years ago on 6 January, Alfred Wegener presented his continental drift theory for the first time. The Blogosphere was full with articles, among them: more
Dear colleagues,
We would like to bring your attention to a special session at the 2012 Annual Meeting of the Seismological Society of America (17-19 April, 2012, San Diego, California): “Macroseismic Effects in Recent and Ancient Earthquakes and their Relationship to Ground Motion Parameters”. more
Let’s start with some good news: The first two Galileo satellites (Natalia and Thijs) will be launched today from Kourou. It’s a little behind the schedule (6 years) and the entire project has become a little more expensive than previously thought (1,600,000,000 €), but who cares? It will provide 1 m GPS resolution! 1 m!!!
There is one more Archaeopteryx! Really! Soemone who does not want his name to be told handed out the fossil to scientists. After a thoroughly investigation of that great piece of Solnhofen Plattenkalk, the anonymous collector will get back his bird. No, his dinosaur I mean. Ehm, his Archaeopteryx.
Dave Petley reported on a giant landslide in Iceland. It’s expected to have ~1,000,000 m³. See the amazing images, just great.
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

Paleoseismicity.org is a page dedicated to scientists and everyone else interested in paleoseismology, archeoseismology, neotectonics, earthquake archeology, earthquake engineering and related topics. Different authors irregularly write about recent papers, field work, problems, conferences or just interesting things that they come across. We intend to provide a platform for discussion and scientific exchange. Interested in joining as an author? Please contact us!
paleoseismicity.org is edited by Christoph Grützner and administrated by Martin Schmidt, Koblenz/Germany
