| Abstract: | The development of innovative and quantitative methods is one of the main
ingredients for future progresses in volcanic risk assessment and management
at long- and short- term time scales.
The complexity of volcanic systems originates from the strong heterogeneity
of their internal structure (in terms of spatial variation of physical rock properties)
and the large variety of thermomechanical processes which may precede
and accompany the magma rise and eruption. The most comprehensive
understanding of volcanic processes necessarily calls for a multi-disciplinary,
integrated approach of data acquisition, analysis and modeling.
During the past three decades, we have been witnessing a strong technological
development leading to a rapid growth of multidisciplinary studies of
volcanoes. The controlled, repeatable experimentation is nowadays replaced
by dense monitoring surveys, where the analysis strategy is often dictated
afterwards, depending on the data produced. Volcano monitoring networks
(geophysical, geochemical, geodetical, …) produce terabytes of data, only a
small fraction of them is practically used for research and/or survey purposes.
It comes out the need for implementing new strategies of data management
able to analyze and mine in the near-real-time huge data flows, having the targets
1/ to exploit the whole available information, 2/ identify and measure
quantitative risk indicators useful for volcanic risk monitoring and emergency
management and 3/ develop advanced tools for process simulation and event
prediction based on the real time analysis and modeling of observed data.
Due to the multi-disciplinary nature of the object under study, innovative
approaches and techniques for volcano monitoring may concern an ultra-wide
disciplinary domain (geophysics, geochemistry, geology, remote sensing, …).
The collection of articles in this volume represents an exhaustive description
of the main outcomes of the INGV-DPC V4 project “Conception, verification,
and application of innovative techniques to study active volcanoes” that
we have coordinated during 2005-2007 and which has seen the participation
of 14 national and international research units.
In the project development the innovation has been focussed on a restricted
number of tasks which were believed to be prior in terms of needed scientific
effort and development and possible gain of knowledge about volcanic
processes.
The Task 1 of the project (Probabilistic volcanic hazard estimation) was aimed at
the estimation of volcanic hazard based on probabilistic techniques and eruption
forecasting. In this framework the research activity was devoted to developments
of prototypes of software/codes, strategies for the development of
quantitative tools to analyze multivariate seismic database, find precursory patterns
of volcanic eruptions, and define probabilistic rules to quantify shortterm
volcanic hazard, applications to case studies.
The main issue in project Task 2 (High resolution seismic imaging of volcanic structures)
was the analysis and modelling of seismic waves propagating through the
complex volcanic medium with the aim to extract relevant information about
structure, depth location and geometry of the feeding system.
Since the initial TOMOVES experiments around Mt Vesuvius in 1993 till the
SERAPIS project in Campi Flegrei bay area in 2001, the active exploration
tools have demonstrated to well complement passive observations standardly
performed by volcanological observatories. In this task most of applications
have been devoted to a better understanding of the Campi Flegrei caldera
structure through the adaptation of existing tools to the complexity of acquisition
and modelling in volcanic environments, while new tools have been
developed, especially for the imaging of local elastic/anelastic properties of
the volcanic medium.
The main objectives of Task 3, was the development, implementation and
testing of new tools for realtime analysis of seismic and thermal monitoring
data, and to design and test of a prototype, sea-bottom multi-parametric station
integrated to an on-land existing monitoring network. Automatic techniques
for real-time detection and location estimation of seismic events have
been developed and made able to work in 3D heterogeneous volcanic structures.
Concerning the experimentation of prototypes for data acquisition in
hostile environments it has been developed and tested a sea bottom seismic
station with real time transmission connected to the monitoring system of
Neapolitan volcanic area. New instruments for thermal monitoring have been
conceived along with tools to analyze thermal images in near real-time.
The researches and results described in this volume follow the new trend of
modern volcanology, where the multi-disciplinary observation is combined
with advanced modelling tools and innovative technologies for monitoring of
volcanic processes.
We hope this book can represent an useful reference for volcano researchers
and technology developers. |
