For the period of June-September, 2017, the Group of Magnetotelluric Sounding conducted the soundings of two cross-sections in the territory of Kyrgyzstan to conduct detailed study the Tian Shan fault zones. On the “Karabook” cross-section, in Orto-Syrt River and At-Bashi River Valleys, the observations were made in 15 sites by MTS method, and on the “Chon-Tuz” cross-section in Kochkor Valley – in 24 sites.

Additionally, in Koch-Kor Valley, in 2 sites of two earlier acquired cross-sections, the synchrony long-term MT soundings had been conducting for 11 days. The aim was to increase the deep of observations. Similar works were also conducted in Issyk-Kul Lake depression, near “Karagai-Bulak” Regime Station, where observations took more than 8 days.
