The Main Kopetdag fault (MKDF) of Turkmenistan is a key tectonic feature within the active tectonics of the Arabia-Eurasia continental collision and the geodynamics of the South Caspian basin. The fault runs along the edge of the Kopetdag (or Kopeh Dagh) mountains, which form the northern margin of the Arabia-Eurasia collision zone. The tectonics are complicated by proximity to the South Caspian Basin, which is an enigmatic ‘block’, filled with up to 20 km of Cenozoic sediment, and possibly floored by oceanic crust of Mesozoic age. The South Caspian is moving relative to its surroundings, with a roughly northwest motion relative to Eurasia that introduces oblique right-lateral and shortening components across the western Kopetdag. The lateral component decreases eastwards as the influence of the Caspian diminishes, and the Kopetdag instead accommodates Arabia-Eurasia shortening.
In the framework of our NATO-funded project SPS G5690 – “Earthquake Hazard and Environmental Security in Kazakhstan and Kyrgyzstan” we will run an ~1 hr online webinar. Ramon Arrowsmith from Arizona State University will talk about Seismotectonics and surface rupture of large intraplate earthquakes: an example from the M7.8 1911 Kebin (Chon Kemin) Earthquake, Northern Tien Shan, Kyrgyzstan.
The webinar is open for everyone interested and will be held via zoom (https://uni-jena-de.zoom.us/j/8941887790 Meeting-ID: 894 188 7790; Password: EQAsia).
Date: 30 May, 2022
Time: 3 pm UK time (3 pm London; 4 pm Berlin & Paris; 10 pm Beijing; 7 am San Francisco)
On 26 April, 2022, Jean-Francois Ritz from Géosciences Montpellier talked about Unprecedented surface rupture and shallow fault reactivation during the 2019 Mw 4.9 Le Teil earthquake, France: What does paleoseismology reveal? in the framework of our NATO-funded project SPS G5690 – “Earthquake Hazard and Environmental Security in Kazakhstan and Kyrgyzstan”. In case you missed Jeff’s presentation, here’s the video.

In March 2022 we spent a week in Uzbekistan discussing projects and undertaking field investigations in collaboration with the Institute of Seismology, National Academy of Sciences.
Uzbekistan is sited at the westernmost margin of the Tien Shan ranges, with environments ranging from high mountains along the borders with Kyrgyzstan and Tajikistan through to desert in the west. There is a proven widespread earthquake hazard, with examples of destructive earthquakes including an event in 1966 that caused widespread destruction in the capital city of Tashkent.
On 28 March, 2022, Kathryn Fitzsimmons from the University of Tübingen gave a talk about What goes on between the mountains and the deserts? A sedimentary view of past environments along the Tien Shan piedmont in the framework of our NATO-funded project SPS G5690 – “Earthquake Hazard and Environmental Security in Kazakhstan and Kyrgyzstan”.
