evidence: Seismotectonic study of the Fergana Region (Southern Kyrgyzstan): distribution and kinematics of local seismicity [...] The Fergana basin is an east-west-trending intermontane basin filled with up to 8 km of Cenozoic sediments situated in the southwestern part of the Tien Shan (Bazhenov 1993; Thomas et al. 1993; Cobbold et al. 1996). The Tien Shan mountain belts stretch east-west for more than 2,000 km, with elevation exceeding 7,000 m in places (Nelson et al. 1987). The maximum topographic relief between the Fergana Valley floor with an altitude of roughly 450 m and the surrounding mountain peaks is about 4,500 m.
