“…Thus, the time history of the shocks preceding the September eruptions, suggests a NW-SE feeding dyke direction (SCHICK et al, 1982), which is in good agreement with the main tectonic trends of the area.…”

“…According to SEIDL et al (1981), andSCHICK et al (1982), there is some evidence that at Mt. Etna, which is normally in persistent activity with open conduit, high tremor amplitude is linked to a strongly turbulent movement of a high level magma column, due to violent unmixing and migration of the gas phase.…”

“…This fact is, for instance, a typical feature of volcanic tremor observed at Etna and Stromboli. In the case of 'normal' activity, tremor can show, over many months, a high degree of stationarity (see for instance Figure 3 in Schick et al, 1982).…”

Signal characteristics and intensity patterns of volcanic tremor are discussed with regard to eruption phenomena. Although a generally valid relationship cannot be given, volcanic tremor is strongly correlated to the fluid dynamics of the volcano. A major difficulty in the interpretation of volcanic tremor is the lack of an appropriate source model. It is assumed that flow transients of quite different kinds act as seismic sources. The significant correlation of volcanic tremor to external forces (barometric pressure, rain-fall loading, earth tides) is discussed and included in a relation with magma-flow instabilitiesl Twophase (liquid-gas) flow instabilities play an essential role in the origin of volcanic tremor and, possibly, in the occurrence of volcanic eruptions. A model is discussed, in which one cause of tremor is seen in self-sustained pressure oscillations following transitions between subsonic and supersonic two-phase magma flow (modified Steinberg and Steinberg model).
