Now that the abstract submission deadline has passed you might be interested in somehow paleoseismicity-related sessions at the EGU2012. I decided to group the session by topic and my choice is absolutely based on personal interests. Sorry if I don’t mention every earthquake-related session.
Emil Wiechert was born 150 years ago (26 December 1861). He not only invented modern Geophysics and Seismology, but he also had the first chair of Geophysics worldwide (1898 in Göttingen, Germany). Wiechert became famous for his seismograph. Now the Deutsche Post released a special stamp showing Wiechert, his seismograph and the original seismogram of the 1906 San Francisco earthquake as registered in Göttingen, Germany!
Some preliminary results regarding geological, engineering and social aspects from the Van Mw 7.2 earthquake (23 October 2011) in Eastern Turkey from Prof. Lekkas and Prof. Karydis visit to the site. Have a look at the following link:
Update: According to a press release from Bogazici University, intensities reached VIII. They also claim a depth of 5 km only. 138 people died, 350 were wounded and 970 buildings collapsed.
An earthquake with a magnitude of Mw 7.2 (EMSC: Mw 7.3) occured in Eastern Tureky in a depth of 10 – 20 km. The epicentre was situated close to the city of Van. More than 30 houses collapsed according to first reports. Despite only several dozens of people have been confirmed dead until now, the earthquake could have caused hundreds of fatalities. Surprisingly, the quake did neither happen at the North Anatolian Fault Zone nor at the East Anatolian Fault Zone. Those two strike slip systems are considered as the most dangerous faults in Turkey. The Van area lies in a broad zone of convergent movement of the Arabian plate vs. Eurasia, and mapped faults are in concordance with the oblique thrust mechanism observed at the 23 October 2011 event. Convergence rate is in the order of 25 mm/a there. Continue reading “M 7.2 earthquake hits Eastern Turkey, causes intensity VIII”
