| Abstract: | Macroseismic studies, linear refraction profiles, and a two-dimensional seismic array study on Mount Etna, have all detected anomalous low velocity zones beneath the volcano. Seismic travel time delays together with high frequency attenuation observations confirm the presence of a large volume of partial melt beneath the volcano. A simplified three-dimensional model of the main storage system of Mount Etna is presented.Paper presented at the Symposium  Volcanoes of the Earth and Planets , held at the University of Lancaster, March 17, 1981. |
