Annals of Geophysics, the former Annali di Geofisica, published its latest issue today, dedicated to the 2012 Northern Italy earthquakes: Vol 55, No 4 (2012): The Emilia (northern Italy) seismic sequence of May-June, 2012: preliminary data and results. On 20 May 2012 an earthquake with a magnitude of Mw6.1 hit Finale Emilia, on 29 May an Mw5.8 event followed. The earthquakes caused a number of fatalities and significant damage. Earthquake environmental effects were widely observed, too. more

New papers: paleotsunamis in Oman, Tohoku-oki tsunami 2011 in Japan
2012-09-26 | in Paper, UncategorizedTwo new tsunami papers have been published recently, and I am happy to be co-author of one of them. In Hoffmann et al. 2012 we report on our observations along the NE Omani coast between Fins and Sur. We found a ridge of imbricated boulders parallel to the coast, but in heights of several meters above m.s.l. on top of a cliff and dozens of meters inland. Also, extremely large blocks clearly stemming from the cliff were found. We used LiDAR to determine the mass of very large blocks (up to 40 t) and found this method to result in far lower weights than estimated with the classical method. more

Ancient Geohazards in the Eastern Mediterranean – Call for posters
In the frame of the forthcoming international workshop “Out of Rubble: Interdisciplinary Perspectives on Minoan Earthquakes” (Leuven, Belgium, 29-30 November 2012), we welcome poster proposals on the topic “Ancient Geohazards in the Eastern Mediterranean”. Posters should address any issue related to the definition of ancient geohazards in the Eastern Mediterranean (e.g. tsunamis, earthquakes, volcanic eruptions, extreme climatic events).

New papers on the Sparta Fault, Greece and the Wasatch Fault, Utah
2012-09-13 | in Earthquake, PaperThe Sparta Fault in Greece is marked by one of the most impressive mountain fronts I’ve ever seen. A huge (yes, huge!) fault scarp has developed, traceable for kilometers; the fault itself is more than 60 km long. Ancient Sparta has been devastated by the last known major (M>7) earthquake that happened at this fault in 464 BC. Now, Papanikolaou et al. have published new data on this fault. They examined how paramaters like throw, segmentation, and catchments vary along strike and created a new seismic hazard map, showing a site-specific long-term recurrence interval of ~1.8 ka (+/- 450 a). more

New paper on archeoseismological investigations in Cologne, Germany
2012-09-11 | in Paper | 2 responsesA new paper has been published online first by Hinzen et al. on their archeoseismological study in Cologne, Germany. During recent archeological excavations, a number of damaged structures from Roman to Medieval times have been discovered and described among them a synagoge, the Praetorium, and a Roman well. Since damaging historical earthquakes are documented for the Lower Rhine Embayment, seismic shaking was a good guess to have caused the observed damage. more

New papers: L’Aquila, Balochistan EQ, tectonic geomorphology, geophysics in Mongolia
2012-08-13 | in PaperAfter I came back from one week of holidays I checked the latest papers. Surprisingly, one was by myself! Finally IOP published our work on combined geoscience techniques in the Orkhon Valley, Central Mongolia. We used Georadar, SQUID-gradiometers, capacitive-coupled geoelectrics, octocopter stereoimages, shallow drillings, datings, and archaeological excavations for an geoarchaeological project. Using geophysical, archaeological and geological observations, we assumed a dating in the Turk/Uighur period (6th–9th century AD) and a re-use under Mongolian reign (12th–17th century AD). This would mean that this site is the furthermost walled structure in the peri-urban area of Khar Balgas. more

New papers – Minoan earthquakes, catastrophism, archaeoseismology in Israel, Costa Concordia
2012-08-01 | in PaperCurrently I spend my time working on some papers that deal with tsunamis in the Eastern Mediterranean and earthquakes in Spain. Searching for literature and looking for data on the Minoan catastrophe I came across this new open access publication by Simon Jusseret and Manuel Sintubin:
- All That Rubble Leads to Trouble: Reassessing the Seismological Value of Archaeological Destruction Layers in Minoan Crete and Beyond. Seismological Research Letters, 83, 4, 736-742, doi:10.1785/0220120011.
Our colleagues from IGCP567 – Earthquake Archaeology put a lot of effort into getting rid of catastrophism and into making archeoseismology a more reliable, quantitative science. By the way, don’t miss the next workshop on archeoseismology and active tectonics in Mexico 2012! more

Primary Fault – Science meets fiction, geophysics meet fantasy
2012-07-31 | in Paper | one responseIt’s holiday season, and many avid readers might need an advice on new books. Here’s one for the earthquake community: Primary Fault by Sharon Kae Reamer. The title reminds you of geology? This is no coincidence. The author reminds you of geology? Right! Sharon Kae Reamer is a seismologist, currently working at the seismological observatory of Cologne University. You probably know her work when you are into archaeoseismology, seismicity in Germany, or seismotectonics. Now she has published her first novel, and seismology does play a role. more

Special Issue: Active Faults in Iberia (Journal of Iberian Geology)
2012-07-02 | in PaperThe Journal of Iberian Geology has now published a Special Issue “Active Faults in Iberia“, with J.J. Martínez-Diaz, E. Masana, and M.A. Rodríguez-Pascua as guest editors: J Iber Geol, 38 (1), 201. This volume comprises a great collection of new data on active faults, paleoseismology, intraplate earthquakes, and seismic hazard. One article also introduces the Quaternary Active Faults Database of Iberia. And the best thing is – all articles are open access and available for download! more

Two new paper on the Tohoku Tsunami, Japan, 2011
2012-06-25 | in Japan Earthquake, Paper | one responseTwo new paper have recently been published on the Tohoku Tsunami that devastated the Japanese coast in March, 2011.
In Sedimentary Geology, Chagué-Goff et al. published their results from investigations of chemical markers left by the waves in March, 2011. The authors sampled the tsunamites two, five and seven months after the event and determined the concentrations of chemical markers such as C, Ca, Cl, K, N, S, and Sr. more
