In the winter months of 2018-2020 Kola Branch Unified Geophysical Service RAS conducted experiments on joint registration avalanches in Khibiny mountain range using seismic and infrasonic sensors during work forced descent snow mass. The aim is to assess possibility avalanche detection geophysical methods. lack representative statistics frequency regularity reason for relevance developing metho...

Wavelet transforms originated in geophysics in the early 1980s for the analysis of seismic signals. Since then, significant mathematical advances in wavelet theory have enabled a suite of applications in diverse fields. In geophysics the power of wavelets for analysis of nonstationary processes that contain multiscale features, detection of singularities, analysis of transient phenomena, fracta...

In the last decade several techniques have been developed to enhance geophysical data in order to extract subtle features that reflect the structural geology of the area. These techniques include curvelet, ridglet and wavelet analysis. Although these techniques provide a powerful tool in extracting linear features from geophysical data, they lack the power to resolve curvilinear or circular fea...
