What happened, where and when?
On 7 August 2023, around 17:00 local time, mudflows occurred in the villages of Ken-Suu, Bayzak, Taldy-Suu, Korumdu, and Koochu in the Tup district of the Issyk-Kul region due to short-term rains. The Ministry of Emergency Situations (MoES) and local authorities formed a joint commission to have thorough and transparent assessment of damages. According to the MoES and local authorities, 200 households were directly impacted by the disaster, however, preliminarily, 60 per cent of the total population (13,000 people) of the five affected villages were identified as in need of assistance of various degrees.
Traditionally, the western part of the Issyk-Kul lake had monthly average of only 115 mm of precipitation, while on the eastern shore about 600 mm. However, due to changing climate, the amount of precipitation has increased in recent years in this part of the country.
The table below shows maximum temperature and average monthly precipitation data for Tyup district for 1991 – 2021:
Months June July August September
Maximum temperature (°C) 20.2 22.1 21.9 18.1
Volume of precipitation (mm) 143 149 137 99
During 1 - 10 August 2023, high temperature ranging +29 - 31 °C took place in Tyup district while the average maximum was +22 °C, with particularly high precipitation volume during the same period, which increased from normative 15 mm/day to 27.1 mm/day as a result of rapid rains. This resulted in increased volume of water during a short period of time, leading to river overflows and floods.
Due to sudden and increased level of precipitation as well as mountainous location, the increased volumes of water flowed down the hill towards affected villages, resulting in mudflows and spillover of rivers going near and through villages. The disaster ruined and blocked main roads going to and out of villages, damaged residential and non-residential buildings, power outage due to polls being torn and electricity lines disrupted, and with cemeteries and animal burials flooded, there is increased likelihood of disease outbreaks
