Abstract: During the 1998-1999 Antarctic survey, a considerable increase of the seismo-volcanic activity took place in Deception Island. About 2000 volcano-tectonic (VT) local earthquakes were recorded by a 16-channel, small-aperture (300 m)seismic antenna deployed in Fumarole Bay between January and February of 1999. The analysis of these data allowed to determine the hypocentral positions of a subgroup of 836 VT earthquakes, using classical array techniques and ray tracing for source location. The detailed study of the waveforms evidences the presence of multiplets. A precise relative location using the relative slowness estimate (RelSE) method allows to define planes of fracture for the multiplets of the series.
