**2. Areas of seismic centers origin in South Siberia and Russian Far East**

Based on the earthquake epicenters distribution and maximal volumes of seismic energy releasing we located, with certain care, five specific areas of origin of seismic centers (OSC) with seismic energy volumes calculation in them. Active faults limit the majority of these areas. The fulfilled investigation of these intracontinental areas allows showing increased seismicity distribution in south Siberia, Far East and adjacent territories. Below we consider geodynamics and seismicity of each from five selected OSC areas.
