Proceedings of the Royal Society of London get free online access

The Royal Society of London ‘for Improving Natural Knowledge’, the world’s oldest scientific publisher, made its journal archive permanently free to access online. The first edition of Philosophical Transactions of the Royal Society appeared in 1665. Now, the archive contains more than 60000 papers. Here are the links to the press news and to the searchable archive.

Among the many papers of potential interest, I found the following two: “Observations on the parallel roads of Glen Roy, and other parts of Lochaber in Scotland, with an attempt to prove that they are of marine origin“, by a rather young Charles Darwin (1839) and “On the small vertical movements of a stone laid on the surface of the ground” (1901), where 2 mm/y “subsidence” was found through a smart and accurate mechanical approach (at least till when the stone disappeared). I stop here to not ruin your curiosity, but you can read more.

What’s up? The Friday links (20)

The Turkey M7.2 earthquake turned out to be a really desastrous event. More than 500 people died, more than 2,000 houses were destroyed. Currently, international aid is reaching the epicentral area. Chris Rowan has a good article on the geological background (an earlier one here), History of Geology discusses the paleoseismicity of that region. The German Aerospace Agency (DLR) prepared some quick response maps for the Van and Ercis areas. Nice work!

M 7.2 earthquake hits Eastern Turkey, causes intensity VIII

Update: According to a press release from Bogazici University, intensities reached VIII. They also claim a depth of 5 km only. 138 people died, 350 were wounded and 970 buildings collapsed.

An earthquake with a magnitude of Mw 7.2 (EMSC: Mw 7.3) occured in Eastern Tureky in a depth of 10 – 20 km. The epicentre was situated close to the city of Van. More than 30 houses collapsed according to first reports. Despite only several dozens of people have been confirmed dead until now, the earthquake could have caused hundreds of fatalities. Surprisingly, the quake did neither happen at the North Anatolian Fault Zone nor at the East Anatolian Fault Zone. Those two strike slip systems are considered as the most dangerous faults in Turkey. The Van area lies in a broad zone of convergent movement of the Arabian plate vs. Eurasia, and mapped faults are in concordance with the oblique thrust mechanism observed at the 23 October 2011 event. Convergence rate is in the order of 25 mm/a there. Continue reading “M 7.2 earthquake hits Eastern Turkey, causes intensity VIII”

What’s up? The Friday links (19)

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.

New paper on L’Aquila earthquake

Based on a new inversion of InSAR data, De Natale et al. predicted that the Avezzano and Sulmona tectonic domains, in Central Italy, may anticipate by 15-20 yr the next large earthquake, as a result of stress transfer. Avezzano and Sulmona were razed by a large earthquake in 1915 and 1706, respectively.
