Gravity measurements have been carried out at Mt Etna since 1986. The gravity network is now composed of 71 stations 0.5 to 3 km apart, covers an area of about 400 km2 and consists of four integrated subarrays: the Main Network; the Summit Profile; the E-W Profile and a Base Reference Network of 4 stations placed at the towns of Adrano, Belpasso, Zafferana and Linguaglossa, each of which is considered to be stable with respect to volcanic activity; all the other networks are connected to this reference network. A calibration line was also established in February 1995 to investigate systematic variations in instrumental calibration factor with time.

Abstract
Gravity measurements have been carried out at Mt Etna since 1986. The gravity network is now composed of 71 stations 0.5 to 3 km apart, covers an area of about 400 km2 and consists of four integrated subarrays: the Main Network; the Summit Profile; the E-W Profile and a Base Reference Network of 4 stations placed at the towns of Adrano, Belpasso, Zafferana and Linguaglossa, each of which is considered to be stable with respect to volcanic activity; all the other networks are connected to this reference network. A calibration line was also established in February 1995 to investigate systematic variations in instrumental calibration factor with time.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
