As a result of SGDM-A mapping, different structural zones were indicated on the polygon “Buchankii” during the period 1993-2001. Repetitive surveying in 2001 approved location of anomalies, but their intensity changed. It is expected the value of d (ratio of sum anomaly criterion K1 and K2 calculated for different years) would to relect the change dynamic of geologic media. Increasing of d connected with increasing of azimuthal conductivity anomaly level in the upper part of geological medium and vice versa. It is concluded that direction of upper geological medium azimuthal conductivity (evaluated by d) marks areas of current erosional geological processes (gullies, landslides, etc.). Areas with higher levels of d indicate with high probability areas of dangerous processes development. So SGDM-A should to direct use for localization these areas with measure step one third from minimal length of potential active sliding body. Another predicative feature of active zone is polyvectors figure of anomaly diagrams of SGDM-A where ratio of the longest vector to the shortest one will seek to minimize.
