Аннотация:Abstract
Examples of the regional modeling on the basis of the seismotomography data are considered. The formulations of regional problems are analyzed and their ill-posedness and uncertainty of the results due to artificial conditions imposed on the region boundaries are discussed. To improve the modeling it is proposed to preassign additional regularization conditions and to bring the lower computation-domain boundary into coincidence with the interface between the upper and lower mantles. A new technique of regularizing solutions based on the use of geological data is proposed. The results of the calculations of the Mesozoic geodynamics of the Arctic region in which the positions of the subduction zones and the Arctic plume are preassigned are presented.
