Archeoseismological investigation of the Kurmenty medieval settlement site, northeastern Issyk-Kul region, Kyrgyzstan

Archeoseismological studies of the Kurmenty settlement have proved the seismogenic origin of the deformation in the walls at this site. The radiocarbon age of the first seismic event damaged the walls of the settlement is 7th century AD. The second seismic event occurred a few centuries later, probably in the late Middle Ages. The strongest seismic events of North Tien Shan occurred in the late 19th–early 20th century as the Chilik (1889, M = 8.4) and Kebin (1911, M = 7.9) also damaged the walls of the Kurmenty settlement. The local shaking intensity during these seismic events was I ≥ VII on MSK-64 scale.
