Workshop report – quaternary dating and hazards at CEREGE, Aix-en-Provence, France

A number of earthquake specialists assembled in Aix-en-Provence for a four-day workshop hosted at CEREGE. The workshop is one of the flagship activities within the framework of the NATO SPS Multi-year project ‘Geo-environmental security from earthquakes in Kazakhstan and Kyrgyzstan’. This project involves a consortium of researchers and specialists from Asia (Kazakhstan and Kyrgyzstan), from the USA, and from Europe (France, Germany, UK). We aim to develop the underpinning geological data that is required for building effective earthquake resilience, and to compile this data in open access formats that are accessible for researchers within the project focus area of central Asia. We combine that aim with the development of capacity through equipment purchases and through the training of early career researchers from both NATO and NATO partner countries.

Video: talk by Ramon Arrowsmith on “Seismotectonics and surface rupture of large intraplate earthquakes: an example from the M7.8 1911 Kebin (Chon Kemin) Earthquake, Northern Tien Shan, Kyrgyzstan”

On 30 May, Ramon Arrowsmith from Arizona State University talked about Seismotectonics and surface rupture of large intraplate earthquakes: an example from the M7.8 1911 Kebin (Chon Kemin) Earthquake, Northern Tien Shan, Kyrgyzstan in the framework of our NATO-funded project SPS G5690 – “Earthquake Hazard and Environmental Security in Kazakhstan and Kyrgyzstan”. In case you missed Ramon’s presentation, here’s the video.

We’re going to have a summer break and commence our webinar series in autumn. Watch this space for future talks, which take place always on the last Monday of every month, and follow us on Twitter for updates: https://twitter.com/QuakesCentAsia.

The Main Kopetdag fault of Turkmenistan: from palaeoseismology to geodynamics

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.

Combining palaeoseismic and archaeological records along the Silk Roads of Uzbekistan

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.

Map of the sites visited during our trip along with active faults from the AFEAD database and historical earthquakes from the EMCA database.

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.
