Today’s post of the Landslide Blog about a rockfall caused by a volcanic earthquake reminds me about something that’s in my mind for years already. Could we use dust deposits as a paleoseismological archive? Dust clouds of all sizes, ranging from tiny to huge, can be associated with seismic shaking, especially in arid and mountainous regions. Here I have collected a few videos I found on YouTube. When large amounts of dust settle they should form a distinctive layer recognizable in the sedimentary record, comparable to volcanic ash deposits. Of course they will be harder to be identified, since the material is the local one. I guess this could be done, similar to turbidites in marine paleoseismology. There are papers that describe changes in the aerosol content in the atmosphere after earthquakes, so why not look for them on earth? more

It’s been a while since the last Friday links, so today’s list is rather long. Of course the Russian meteoroid-meteor-meteorite (yes, in this order!) was an absolutely amazing, though destructive phenomenon. The air blast was registered equivalent to an earthquake of magnitude 2.7. Read Livescience’s article here and read this text to get to know about meteors and seismograms in general. more

After the great reports of Raúl and Pedro from the fieldtrip, I just want to say thank you to the organizers again. I also want to share a few photos. See you all in Aachen, 2013! more

The following two reports are from the fieldtrip to lake Patzcuaro by our friends Pedro Huerta and Raúl Pérez López. This excursion marked the end of the Morelia2012 workshop on Active Tectonics, Paleoseismology and Archaeoseismology. more

Buenos dias! This is an update from the last day of presentations, tomorrow there will be a field excursion to the Patzcuaro area (1858 eq event). Unfortunately Christoph and I cannot join the field trip, because we booked already our flights for Friday. But we will keep you informed. Are you wondering what the title photo is?

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. more

The 3rd INQUA-IGCP 567 Int’l workshop on Earthquake Geology, Paleoseismology and Archaeoseismology has started here in Morelia, Mexico. We are going to cover the sessions whenever we have time to drop a few lines, however, we can not comment all talks and posters.

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! more

The preliminary program of the 3rd INQUA-IGCP 567 Workshop to be held at Morelia (Mexico) from 19 – 23 November 2012 is out now. This program is subject to very minor modifications regarding social events, etc.. The scientific program will be the definitive one, but might be subject to late unforeseen inconveniences.

Please note that some dates like the field trip have changed! more
