Seismicity of European north-eastern Russia and methods of geodynamic monitoring for its nature study

Possible geologic sources of scattered seismicity on the territory of Komi Republic are considered. Methods of their instrumental long-term geodynamic study were specified. Two geodynamic polygons for short-basis measurement were created. Zero cycle of measurement was done for these polygons and high resolution (2—4 mm) coordinates of polygon reference marks were obtained.
