In a 20 mins interview with Space Race, Richard Walker talks about our work on large earthquakes and active faults in Central Asia, tectonic geomorphology, our use of satellite data, DEMs, and much more.

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.
Ben Johnson, a PhD student from the University of Oxford, describes his experiences from fieldwork over the summer of 2021. Read on to find out more about the Alai valley, glacial histories, and shortening across the northern margin of the Pamir.
The South Caspian Basin (SCB) is an aseismic block that moves independently to its surroundings. Together with the Arabia-Eurasia collision, it controls the active tectonics of Turkmenistan. The directions, rates, and rotation poles of the SCB relative to Iran and Eurasia are not well resolved. In a new paper recently published in TECTONICS, we constrain the motion of the SCB by measuring the slip rate of the Main Kopeh Dagh Fault (MKDF) in Turkmenistan. Here’s what we found:
In November 2021 two of us (Ian Pierce and Richard Walker) were able to travel to Baku to begin a collaborative project between the Azerbaijan National Academy of Sciences and the University of Oxford addressing regional tectonics, active faulting, and earthquake hazard. The project was due to begin in early 2020 but was postponed due to travel restrictions.
The COMET Central Asia Fault Database integrates decades of fault mapping and field-studies by researchers from the UK NERC Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET), and global collaborators.
Central Asia is home to one of the world’s great mountain ranges–the Tien Shan–which is formed by vigorous crustal convergence across a multitude of tectonic faults. Here we describe the motivation to assemble the database and the choices that we have made in its structure, which are based on utility, necessity, and limitations in available information. We are working towards a full public release of the dataset, so keep an eye out!
