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.

Journey to the Roof of the World: how fast does the Pamir Frontal Thrust move?

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 Pamir and Tien Shan are colliding along the Alai valley as part of the wider India-Eurasia continental collision. The Pamir are moving northwards along the Pamir Frontal Thrust (PFT), closing the valley. The rate of shortening across the PFT is contested, with short-term geodetic rates from GPS giving faster rates from those measured from palaeoseismology.

New paper: Slip-Rate of the Main Kopeh Dagh Fault and active tectonics of the South Caspian

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:
