Abstract:

The modern geodynamic regime of the Mid-Arctic Ridge in general, and the Gakkel Ridge in particular, is considered on the basis of analysis of seismicity, focal mechanisms of earthquake sources, directions of slip vectors of rock masses in earthquake centers. Complex stress-deformed state of the Earth’s crust within the Mid-Arctic Ridge is established. The fields of stresses and deformation from the south-east to north-west change three times. That is, the stress-deformed state of the lithosphere, which depends on directions of the axes of compressive stresses, changes in the layered block medium by layers, and in some blocks varies with time.
