Artykuł przedstawia wstępne wyniki badań sejsmiczności lodowca Hansa na Spitsbergenie. Dane z okresu 26.07-02.08.2021 r. zarejestrowano za pomocą sieci 8 geofonów jednoskładowych, krótkookresowych, ulokowanej na powierzchni lodowca. Opisana została metodyka badań, w tym algorytmów, które zostały wykorzystane w celu automatyzacji procesów detekcji i lokalizacji wstrząsów lodowcowych. Na podstawie analizy przestrzennej i czasowej zlokalizowanych zjawisk przedstawiono wnioski na temat aktywności sejsmicznej lodowca oraz wykazano skuteczność zastosowanych rozwiązań.
The article presents preliminary results of seismicity studies of Hans Glacier in Spitsbergen. Data from the period 26.07-02.08.2021 were recorded using a network of 8 single-component, short-period geophones located on the surface of the glacier. The methodology of the study was described, including the algorithms that were used to automate the processes of glacial shock detection and localization. On the basis of spatial and temporal analysis of the localized phenomena, conclusions on the seismic activity of the glacier were presented, and the effectiveness of the solutions used was demonstrated.
