1.Scheme of location of earthquake epicenters (at depths of 100 to 200 km) on the territory of Tajikistan and Afghanistan. Compiled by Yu.I. Nuiskov, V.N. Maksimov, V.M. Perekopsky in 1993-1995. There are used the seismic events for the period since 1990 to 1992. The lower boundary of sym.(?) classes is 9.0. The following is added by L.P.Papyrin: 1- axes of deep structures or seismic seams; 2- boundaries of deep structures or seismic seams; 3- location of epicenters of strong earthquakes in this region, within which the epicenter of Usoi earthquake of 1911 is located; area of formation of enormous landslides.


2.Scheme of development of ancient slide dams on Pamir. Compiled by L.P. Papyrin in 1989 by the data of S.M.Vinnichenko and V.V.Lim.

9.The lowered weakened zone in the northern part of Usoi Dam. Here overflow of water from the lake will happen after collapse of the Right-Bank Lake and a hole will appear in the slide dam body. Photo of Leonid Papyrin, 1977.


10.Landslide with a size of 0.9 km3 in the lower still waters of the dam.


11.Beneath is Vahsh. On the opposite left-hand shore is a mountain. At a depth of 350-400 m in it there are the basic constructions of Rogun HEP. Photo of Leonid Papyrin, 2006.
