- Аннотация: A geodynamic model of the modern Earth was constructed based on the SMEAN 2 global seismictomography model. Considering the distribution of mantle temperature anomalies in this model, the numerical simulation of a three-dimensional flow of a viscous mantle was carried out taking into account the dependence of the viscosity on temperature and depth in the spherical Earth. The Stokes equation was solved by the finite element method using the CitcomS code. The obtained data on the distribution of the temperature anomalies, dynamic topography, and velocity field in the mantle were used to analyze structural features and geodynamics in the West Antarctic region, as well as the anomalous acceleration of glacier movement and destruction in this area. In particular, the existence and current activity of the West Antarctic Rift System including one of the largest volcanic provinces on the Earth were explained. This explanation was consistent with the measurement data on increased heat flow on the surface. The increased heat flow and volcanic activity in this region lead to instability and accelerated runoff of the West Antarctic ice sheets into the ocean, thus posing the potential threat of a substantial rise in the global sea level.
