Geoelectrical section on a line West-East
along highway Sevastopol-Yalta (Foros area, Crimea).
The landslide's body (piquets 300-500) is combined by
terrigene rocks and has resistivity more than 20 Ohmm.
Underlying trias-jurassic argillite rocks have resistivity
less than 5 Ohmm. The volume of the slide's body is 200*400*40
cubic metres. Researches were carried out with 25m *25m antennas.

| TEM-FAST 48 complex has been applied for a slide
object research in Baku (Azerbaidjan, April 2000). 50 soundings with
antenna of 25m*25m size has been used when memorial complex and
the slide body investigation and 18 soundings of 50m*50m along
regional profile: Botanic garden-Memorial complex-landslide-prospect
Neftyanikov. The results of interpretation presented as geoelectrical
sections along two profiles (regional and West-East) crossing the
landslide shown in the figures 1,2. The blocks of rock in the
sections indexed by value of specific electrical resistivity
(Ohm-m) are marked with a colour: from red - for low resistance, up
to dark blue - for high.
Assumed tectonic disturbances are shown with subvertical lines.
The body of a landslide has average resistivity 24-36 Ohm-m
and submitted by friable sand-clay formations with residual blocks of
destroyed limestone rocks.
The first slide surface coincides with a roof of clay
rocks and has resistivity from 8 up to 10 Ohm-m. The low resistivity
testifies to presence of water solutions in rocks.
Second and third slide's surface coincided with the layers of dense
clay having the resistivity 5-6 Ohm-m lay below to depth ~ 0.3 Îì-m.
In the top part of the memorial increase of the rock's resistivity up
to 100 Ohm-m which corresponds to the undefeated screening the
limestone layer open by a borehole No 1 (area of the television
center) is observed.
Bedding of the landstones is subhorizontal, while clay bottom rock
have rather steep inclination to east.
