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.
