Earthquake rates inferred from active faults and geodynamics

Vanja Kastelic and Michele M. C. Carafa (INGV, L’Aquila, Italy) recently published an article in the Bollettino di Geofisica Teorica e Applicata (an international journal of Earth sciences) entitled “Earthquake rates inferred from active faults and geodynamics: the case of the External Dinarides.” This article covers the area affected by the earthquake of Ml 4.7 (Mw 4.6) occurred on April 22, 2014.

The same authors also wrote a brief seismotectonic report dealing with such an earthquake. They share the report with us under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

Session on “Seismic hazard modeling”: 86th National Congress of the Società Geologica Italiana, 18-20 September 2012

The Italian Geological Society (Societą Geologica Italiana), founded in 1881, organizes its 86th meeting in Calabria, Southern Italy (18-20 September 2012). The meeting is entitled

THE MEDITERRANEAN: A GEOLOGICAL ARCHIVE FROM PAST TO THE PRESENT

Within this meeting, we will held a session on Seismic Hazard Modelling.

We invite those of you interested to consider participating to the meeting and presenting an abstract (in ours or any other session).

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.

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.
