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…

The Wednesday Centerfault (8) – Virginia M5.8 Earthquake
2011-08-24 | in Centerfault | one responseYesterday, 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

What’s up? The Friday links (18)
2011-08-05 | in The Friday LinksEarthquake 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

What’s up? The Friday links (17)
2011-07-22 | in Teaching, The Friday LinksThis 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.

Public version of the EEE Catalogue online!
2011-07-21 | in paleoseismicity.org, TeachingThe 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

What’s up? The Friday links (16)
2011-07-15 | in The Friday LinksCyprus 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.

The Wednesday Centerfault (7)
2011-07-13 | in CenterfaultThis week’s centerfault is a very prominent one that you will know for sure – the Dead Sea Fault. The sinistral strike-slip fault marks the boundary between the Arabian plate and the Sinai. The entire system is more than 600 km long and has accommodated ~107 km of slip since Miocene. Magnitude 7 is no problem for this structure and the recurrence intervalls are short. more

English report on the Mw5.1 Lorca earthquake out now
2011-07-07 | in PaperThe preliminary report on the Lorca Mw5.1 earthquake from 11 May 2011 is now also available in English! The quake caused a lot of damages to building despite the relatively low magnitude. One building collapsed and nine people died. The report summarized the geological background, environmental earthquake effects and damaged infrastructure. more

The Wednesday Centerfault (6)
2011-07-06 | in CenterfaultThis day’s Centerfault is one of the longest and best investigated faults in Spain, the sinistral Carboneras Fault Zone (CFZ) in Andalusia (36.85°N, 2.25°W). In the north, the CFZ is bounded by the Palomares fault, its southern tip reaches the Gulf of Almería. The NE-SW striking fault zone stretches over 50 km onshore and additional 100 km offshore (Gràcia et al., 2006) and is, therefore, capable of earthquakes with magnitudes > 7. It is one of the three major strike-slip faults in the Betics (Bell et al., 1997). more
