The time patterns of the tremor energy, the strain-release and the space distribution of seismicity during 1990 are analyzed in the present paper in order to provide new data which may be useful for the interpretation of the physical phenomena occurring in the upper crust and related to the uprise of magma and the evolution of volcanic events. The intensity of volcanic phenomena is evaluated by an empirical scale, based on continuous observations of the volcanic activity.

Abstract
The time patterns of the tremor energy, the strain-release and the space distribution of seismicity during 1990 are analyzed in the present paper in order to provide new data which may be useful for the interpretation of the physical phenomena occurring in the upper crust and related to the uprise of magma and the evolution of volcanic events. The intensity of volcanic phenomena is evaluated by an empirical scale, based on continuous observations of the volcanic activity.File in questo prodotto:
