使用三个三分量宽带地震仪阵列记录了埃特纳山的地震波场。对它的偏振和色散特性的分析得出以下结论:(1)波场主要由表面波组成,(2)观察到的两个谱峰是由沿着传播路径的波导效应引起的。
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.
