Calibration of the Khibiny Massif velocity model
using registration of industrial explosions
Monitoring of geodynamic activity of the Khibiny Massif assumes an accurate location of seismic events occurring here. This requires on the one hand knowledge of seismic wave velocities in the massif and adjacent territories and on the other hand software tools for seismic location in inhomogeneous media. The Seismic Configurator program developed in the Kola Branch of Geophysical Survey of RAS enables to create velocity models of 3D media, locate events and compute apparent velocities of seismic waves propagating along different paths. As a result of registration of industrial explosions in Khibiny, a set of apparent velocities of P-waves along paths crossing the massif has been obtained. 2D and 3D velocity models matched the observations have been fitted by these data using the Seismic Configurator program. A method of modification of the existing location system for practical usage of the models has been proposed

Seismological observations of glaciers dynamic on the Spitsbergen archipelago
The paper provides a brief description of results of Spitsbergen glacier observations by the seismic method. The study has been carried out both by permanent and temporary stations data. Characteristic features of glacier-related seismic events have been shown. Main areas of glacier seismic activity on the Archipelago have been revealed. A detailed study of Horsund-fjord glacier activity has been carried out using local seismic station HSPB data. Temporal and spatial distributions of glacier-related events have been obtained for the area. Season variations in temporal distribution of the events have been found
