Morelia2012 workshop – Wed, 21 November

Good morning y ¡buenos días! from Mexico. The second day with scientific sessions is about to start, and after a fuerte breakfast with beans, tortillas, fruits and Mexican coffee we will move to the Centro Cultural Universitario to listen to the talks. The first morning session will focus on Seismic Hazard: Applications, Engineering and Critical Facilities. The second session is dedicated to Archaeoseismology. In the afternoon, an excursion to the historic city center of Morelia will deal with anti-seismic structures in buildings. Continue reading “Morelia2012 workshop – Wed, 21 November”

What’s up? The Friday links (48)

On Thursday, a new seismometer station was inaugurated in the Cathedral of Aachen, Germany. The station is part of the regional network of the state’s geological survey. During recent reconstruction works, we discovered damages in the cathedral that date back to around AD 800. Cracked walls and repaired floors clearly pointed to earthquake damage. Check out these two papers for more info. Then, the idea came up to install a seismometer directly in the cellar of the Cathedral to monitor seismicity and we are quite happy that its ready now!

New paper on the archaeoseismology of Athens

A new paper on the archaeoseismology of Athens, Greece, was published in the Bulletin of Earthquake Engineering by AMraseys and Psycharis. The authors investigated two classical columns at the Akropolis which survived since classical times and modelled the behaviour of the structures under dynamic (seismic) load. They explain observed damages at the columns and also estimate maximum ground movement that would have toppled the columns. It looks like Old Athens has been relatively lucky in terms of earthquakes in the past, despite it is surrounded by active faults… Continue reading “New paper on the archaeoseismology of Athens”

New paper on archeoseismological investigations in Cologne, Germany

A 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.

What’s up? The Friday links (41)

Although I already recommended some papers earlier this week, I have two more to mention: Supawit Yawsangratt and colleagues published new data on “Evidence of probable paleotsunami deposits on Kho Khao Island, Phang Nga Province, Thailand”. Nat Hazards, 63,151-163, DOI 10.1007/s11069-011-9729-4 in a special issue dedicated to tsunami research. Ran et al. presented work on the Wenchuan EQ epicentral area: “Paleoseismic events and recurrence interval along the Beichuan -Yingxiu fault of Longmenshan fault zone, Yingxiu, Sichuan, China.” Tectonophysics (2012), doi: 10.1016/j.tecto.2012.07.013.

New papers – Minoan earthquakes, catastrophism, archaeoseismology in Israel, Costa Concordia

Currently 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:

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!
