It’s not easy to prepare weekly Friday links when you are abroad, this is what I had to realize in April. However, I will try to post a natural beauty each Wednesday in the future, the Wednesday Centerfaults and Centerfolds.
Today, I start with the Kaparelli Fault in Greece (38.22°N, 23.23°E). This beautiful limestone fault scarp is more than 2.5 km long and up to 5 m high. The fault was activated during the 1981 Corinth earthquakes. more
Some days ago, a great new paper was published on the investigation of soft-sediment deformation in paleoseismology: “Alsop & Marco 2011: Soft-Sediment deformation within seismogenic slumps of the Dead Sea Basin. Journal of Structural Geology 33 (2011) 433-457.” The authors investigated the most beautiful seismites I’ve ever seen and generated different scenarios for their interpretation with respect to paleoseismic events. more
A nice short discussion about the Lorito et al., 2011 paper regarding the seismic gap at the Chilean coast and seismic slip during the 2010 earthquake, can be found at Highly Allochthonous. The discussion highlights the paper findings under the glance of the recent Bio-Bio earthquake from Friday, which took place in this so called Darwin gap.
In its latest issue, EOS reports on the European Science Foundation conference “Submarine Paleoseismology – The Offshore Search of Large Holocene Earthquakes” which was held in Obergurgl, Austria from 11-16 September 2010.

The Accredtionary Wedge #30 blog carnival hosted by Mountain Beltway came up with a tasting idea in January: The Geological Bake Sale. Explore and enjoy thematic food like the moon surface cake, the pillow lava bread and the debris flow vegetables. If you create a sweet fault or a tasty trench, we promise to publish it on paleoseismicity.org. more
The California Geological Survey provides a great online-tool for geoscientist: A fault map of California (Alquist-Priolo-Fault-Zone with all datasets available in PDF and GIS format for free! Start here.
A volunteer panel that assesses earthquake risks in Utah said it examined nearly 130 school buildings in the state and found more than half fail to meet federal earthquake safety guidelines. Bad news from here.

The online science magazine “spektrumdirekt” reports on the archeoseismological and paleoseismological studies in Baelo Claudia, Southern Spain. The article focusses on tsunami hazard in the Mediterranean region and the two earthquakes that devastated the Roman town of Baelo Claudia hundreds of years ago. more
The Bulletin of the Seismological Society of America has published a Special Issue on the 2008 Wenchuan, China, Earthquake. This event, also known as the Sichuan Earthquake, was one of the most devastating natural disasters in the last decade. On 12 May, 2008, an earthquake with a magnitude of Mw7.9 happened on the Beichuan fault, leaving at least 69,000 people dead and millions homeless. It is estimated that some $140 billion will be needed to rebuild the damaged infrastructure and houses. more
Nadine published a paper on Lake Ohrid at Biogeosciences (open access): Evolution of ancient Lake Ohrid: a tectonic perspective. Authors are N. Hoffmann, K. Reicherter, T. Fernández-Steeger and C. Grützner, Biogeosciences, 7, 3377–3386, 2010; www.biogeosciences.net/7/3377/2010/ – doi:10.5194/bg-7-3377-2010. Enjoy reading!
