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”
