Three-dimensional model of fractures in the region of Kuril-Kamchatka and Aleutian island arcs connection was created on basis of geological, geophysical and geomorphological data analysis. In the virtual space the seismic focal zone and fault planes of 52 fractures were simulated. Each fracture has got a unique number. The model is represented as a geographic information system of ArcGIS 10.0 combining the map of fractures on the terrain surface,three-dimensional model of fractures and layers-sections at the depths of 10, 20, 30, 40, 50 and 70 km. In separate and attributive tables of geodata base there is information about specific features of fractures location, their belonging to a definite system, characteristic of morphological-kinetic features and ranks, azimuth and incidence angle of a fault plane, depth and activity. The information of geological, geomorphological and geophysical explanation of fractures locationis also given. The tables and layers characterizing fractures are connected and form a relational structure. It gives the possibility to form SQL-queries by MS Access or ArcGIS to obtain different data combinations.
