Abstract
Summary
In this paper we present the initial results from our study of the seismicity generated by the processes in the Perunika glacier, Livingston Island, Antarctica recorded from Bulgarian broad band seismic station LIVV and its relationship with measured GNSS displacements on the glacier surface. Seismic and GNSS data from January 2018 were used. Different types of ice-generated events were observed. About 90 events with identical waveforms, very short duration (up to 1–2 s) and clear P and S onset were localized. GNSS measurements were carried out in five points on glacier and later the velocity in cm/day was computed.
