The Shallow Magmatic Plumbing System at Etna : Method and Technique Development for Temporal and Spatial Evolution

Objective

To recognise the temporal benchmarks in the dynamics of the
feeding system while networks, carried out by use of the same
equipment, will aim at constraining the spatial extent of the
anomalies and their change with time. In more detail, the
principal goals are to improve the precision and coverage of
edifice deformation studies in time and space, to develop and
improve the quality and quantity of methods, hardware and
experience of automated acquisition and management of data, to
detect the spatial movement of magma in the upper few kilometers
of the upper south flank, and to study the relevance of
pre-existing dikes.


The technical approach that will be adopted
will involve the acquisition and interpretation of a great number
of data: satellite (GPS), Triangulateration Survey (EDM, AEDM),
Magneto-Telluric (MT), Spontaneous Polarisation (SP), and
Micromagnetic. All these data will be integrated with the
results from other geophysical techniques to improve the main
picture of the dynamics of the shallow plumbing system. Measured
and theoretical profiles of geophysical change will be correlated
and iterated so that the plumbing system geometry may be
satisfactorily described.

The results of this project are expected to be:

An automated acquisition system, aimed at integrating analogue
and digital geophysical data and at allowing multi-method
quasi-real time processing. An assessment of the contribution of
potential methods in differential (continuous) mode to the
forecast of volcanic unrests. An assessment of the contribution
of automated, direct height and horizontal deformation control to
the forecast of volcanic unrests. An assessment of the
effectiveness of new unconventional devices and/or techniques in
application to the detection and location of shallow magma
intrusion on the opening of fractures at surface. An assessment
of the resolving power in time and space of all the techniques as
above, in application to forecast, detection, modelling and
monitoring of even small magma intrusions. Model for size,
location and inferred physical properties of the shallow plumbing
system; Models for the dynamic behaviour of upper Mt. Etna, with
particular reference to the continued unrest of southern and
eastern slopes, and the inherent volcanic hazard .
