Fault-block structures of the Altay-Sayan folded area (ASFA) southeastern Siberia of Russia were used as the basis for creating a 3-D model. The surface structures were projected to depths by previous correlations between long and deep faults, with all layers and deformation factors defined. The mean deformation factor (Ds) is 0.12 unit/km3 in the upper layer, 0.012 unit/km3 in the intermediate layer, and 0.007 unit/km3 in the lower layer of the 3-D ASFA neotectonic model. Ds allows correlation of the three distinguished layers with rheological bodies that differ in their potential for accumulating elastic energy. 3-D modeling can be used as a methodological approach to projections in seismic prone areas such as the Krasnoyarsk region, for earthquake-hazard monitoring.
