KINEMATIC PARAMETERS OF THE TREMOR WAVE FIELD AT MT ETNA (SICILY)

摘要

The tremor wave-field at Mt.Etna was recorded with an array of three 3-component broadband seismometers. The analysis of its polarisation and dispersion properties leads to the conclusions that (1) the wave-field consists mainly of surface waves and that (2) two of the observed spectral peaks are caused by a wave guide effect along the propagation path.
