Paleoseismological papers in the BSSA April 2013 issue

BSSA’s most recent issue is full of paleoseismological work. The April 2013 issue contains a number of papers dealing with old earthquakes in Turkey, California, Argentina, and Jamaica. Also, there’s info on earthquake catalogues in South America and China. A study on seismic sources in the Lower Rhine Embayment, (W Germany, Belgium, The Netherlands) is especially interesting for me, because it’s right in my backyard. Plus, there are some basic studies on the reliability of paleoseismological investigation and problems in earthquake geology.

Earthquakes and Late Bronze Age collapse: the end of an old myth?

The collapse of Bronze Age civilizations c.1200 BC remains a persistent riddle in Eastern Mediterranean archaeology. Earthquakes, attacks of the Sea Peoples, climatic deterioration, and socio-political unrest are among the most frequently suggested causes for this phenomenon. In the last issue of Seismological Research Letters (January/February 2013), Manuel Sintubin and myself attempt to retrace the origins of the idea according to which earthquakes may have caused the demise of Late Bronze Age Eastern Mediterranean societies. The article features reproductions of unpublished archival documents held by the Cyprus American Archaeological Research Institute (Nicosia). The free-access version of the paper can be found here. Happy reading!

 

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”
