Santorini volcano laboratory. magma evolution and physical volcnaology of historic, prehistoric and quaternary eruptions at santorini - analys of the evolution and behaviour of a hazard relevant volcanic system

Objective

To recognise eruptive processes and associated precursor
phenomena. To provide advanced monitoring techniques and
instrumentation, which aim at the installation of an integral
network to detect precursor phenomena and to enable forecasts of
forthcoming eruptions. To provide a volcanic hazard and risk
zonation map of the Santorini complex, and to advise and educate
public and civil authorities on mitigation actions in case of
reactivation.


The project consist of six interconnected
sub-projects:

Physical processes - Pyroclastic sequences, which will involve
physical volcanology, geochemistry, isotopic studies,
radiochemistry, petrology and geophysics.

Volcanotectonics - Submarine and deep structure, involving
morphotectonics, remote sensing, neotectonic mapping,
quantitative structural analysis, A.M.T., subsurface
stratigraphic investigation.

Petrological study of post- and pre-caldera lavas including
petrological, geochemical, isotopic and fluid inclusion studies,
which will be used to evaluate the pressure, temperature and
volume conditions of the post-caldera magmatic system and its
temporal evolution.

Ground deformation - Thermal monitoring - Civil Defense Planning
consisting of the establishment of a telemetering monitoring
network of sea-level measurement devices integrated with
conventional geodetic measurements (Triangulateration Survey
(EDM)), and satellite geodesy (GPS). Geophysical
(microgravimetric and geomagnetic) measurements. Remote
operating thermal monitoring techniques. Eruptive scenarios,
simulation of gas and ash clouds of Kammeni and Kolumbos volcanic
centers, volcanic hazard and risk maps, education and mitigation
actions.

Seismic monitoring with the deployment of over 12 semi-permanent
seismic stations of analog type on the island of Santorini and on
the neighbouring ones. Seven of these stations will be radio
link connected with the observatory.

Geochemical monitoring by aalysis of major and trace constituents
of water samples. Analysis of gas samples for major chemical
species and some trace constituents (e.g. CO, He,...).
Measurements of 3He/4He and 13C/12C on selected
samples. Continuous monitoring of relevant gas species. Set up
and installation of a telemetering apparatus for CO2 flux
measurement.

The project is expected to lead to a deeper and systematic
understanding of physical processes and the underlying dynamics
of the evolution of this type of caldera volcano, and to the
determination of magnitude-time relation, classification and
interpretation of volcanic earthquakes, the development of
probable eruptive scenarios, and the elaboration of volcanic
hazard and risk maps.
