We carried out archaeoseismological studies in the Southern Issyk-Kul region (Kyrgyz Tien Shan) and obtained radiocarbon datings of the collected samples. These data suggest that the sources of strong earthquakes have occurred in this territory in the 11th and (probably) 16th centuries. These earthquakes had magnitude M ≥ 7 and seismic intensity of at least I ≥ 9. The sources of these earthquakes were associated with the local adyr (piedmont) faults-components of the Pre-Terskei border fault. Our results demonstrate considerable underestimation of the seismic hazard for the South Issyk-Kul region in the latest Seismic Zoning Map of Kyrgyz Republic (2012), which should be taken into account in the construction of the new seismic zoning map for Kyrgyzstan
