Evolution of permeability in Kraa's geothermal eld and associated seismo-
acoustic patterns
○ to determine permeability and resultant volatile flux as well as their evolution with respect to LMU
9
petrology and alteration, in the shallow geothermal field down to the magma/rock interface; Bettina Scheu
○ to link volatile flux through a characterized permeable network to seismic patterns and their
evolution in time.
Deformation processes at Etna through analogue modelling
○ to determine the role of subsurface processes responsible for surface changes, focusing on
frequencies within the transitional window between conventional ground deformation and ULANC
10 seismic investigation;
○ to derive a new interpretation on the role of drivers (e.g. intrusions, gravitational instability, Mike James
hydrothermal system) on measurable surface deformations, with a focus on frequencies
lower than seismic.
Shallow crustal density distribution and its evolution at the Kraa volcanic system
○ to construct a 3D model of the shallow subsurface density distribution by inverting existing
11 and new gravity anomaly data combined with other multi-parametric data; UNIVBRIS
○ to investigate the short and mid-term evolution of the sub-volcanic system from Joachim Gottsmann
continuous and time-lapse gravimetric observation.
Multi-scale high resolution geophysical imaging of Kraa sub-volcanic system
○ to advance multiscale and multi-method (electrical, seismic, magneto-telluric) imaging of
volcanic structures;
○ to monitor and locate seismic activity with a dense seismic network; ISTerre
12
○ to decipher the effect of fluid substitution on seismic and resistivity attributes, with Jean Vandemeulebrouck
application to geothermal exploration and exploitation;
○ to obtain high-resolution geophysical imaging of Krafla's upper geothermal system using
new algorithms based on data fusion and joint interpretation of geophysical data.
Modelling mass balance and stress transfer at the Kraa volcanic system
○ to deploy a network of multi-parameter stations around the Krafla geothermal system (each
station includes an iGrav superconducting gravity meter or a performant spring gravity
meter, a broad-band seismometer, a GPS receiver, a meteorological station, and other (in
particular hydrological) sensors required to monitor mass movement at the shallow GFZ
13
surface); Philippe Jousset
○ to determine subsurface mass and energy transfer from multi-parameter continuous
signals, and develop a model of mass (fluid) displacement in the hydrothermal reservoirs;
○ to define the relative roles in mass and energy transfer of anthropogenic
(injection/extraction) and natural sources.
Automatic detection and classication of relevant events in records from broad-
band ground displacement monitoring devices at Etna
○ to implement an automatic, real time system to analyze the data acquired by the different
types of sensors; UGR
14 ○ to mine ground displacement data from multiple sensors over broad frequency ranges to Carmen Benitez
identify meaningful signals, in particular in frequency domains intermediate between those
typical of seismicity and conventional deformation;
○ to analyse synthetic (model produced) space-time series of ground displacement and
compare them to real data.
Geochemical prospecting and geothermal circulation modelling at Kraa
○ to produce an advanced geochemical conceptual model of the geothermal system and
physico-numerical model of hydrothermal circulation; INGV
15 ○ to realize and test new instrumentation for volcano science and geothermal industry
purposes (in cooperation with WS); Antonio Costa
○ to provide the industrial partner LV with advanced knowledge of the geothermal system for
revised energy exploitation strategies.
