In order to provide a basis for short-term decision-
making in the forecasting and monitoring of volcanic
activity, we developed an entirely automated system
of data acquisition and reduction for magnetic data. The
system (Mag-Net) is designed to provide monitoring and
analysis of magnetic data on Etna volcano at large distances
from the central observatory. The Mag-Net
system uses data from an array of continuously recording
remote stations spread over the volcanic area and linked
by mobile phone to the control center at the local observatory.
At this location a computer receives the data and
performs data sorting and reduction as well as limited
evaluation to detect abnormal behavior or breakdown of
remote sensors. Communication software, called Mag-
Talk, is also designed to provide data to distant users.
With a view to using continuous magnetic observations
in advanced analysis techniques for volcano monitoring,
the Mag-Net system also delivers two graphical user interface
based applications to provide an interpretation
capability. The former, called MADAP, speeds up all the
data reduction processes in order to evaluate the reliability
of magnetic signals. The latter, called VMM, is a procedure
for modeling magnetic fields associated with tectonic
and volcanic activity to facilitate the identification
and interpretation of the sources of a wide spectrum of
magnetic signals.
