The problem of construction of earthquake zones possible with the use of new information technologies in the mapping system MapInfo. Produced detailed seismic hazard assessment based on the analysis of seismic activity zones of articulation of the main structural elements in the allocated time scale and correlating geological preconditions to earthquakes of varying strength with active tectonic structures. Shows the activity of the main tectonic structures of the study area based on estimates of the dynamic parameters in the form of average speed is calculated via the displacement amplitude at a fixed period of geologic time, the direction of displacement and movement kinematics. Set of possible alternate zones of earthquakes in east-west direction with estimates of the maximum possible earthquake magnitude for each zone. The alternation of latitudinal structures of high and low seismic potential confirmed by seismic dislocations found north of the main active tectonic structures. This pattern defines the need for further research to palaeoseismological detail seismic hazard in South Yakutia.
