S1 - Geodynamics and tectonics controlling volcanic systems Open or Close
- Luciano Scarfì (INGV-OE)
- Giovanni Barreca (UniCt)
Landforms and eruptive behavior of volcanic systems worldwide are various and often reflect the complexity of a larger scale geological processes which in many cases govern magmas generation and eruptive style. Indeed, crustal deformation and related tectonic structures play a significant role in magma storage and migration, but also they may exert a fundamental control on differentiation processes, shaping the nature and composition of volcanism.
In this session, we welcome studies aimed at improving knowledge of the Earth’s structure as well as the tectonic and geodynamic framework of those regions where volcanic systems take place. Contributions leading to better understand the relationship between tectonics and volcano activity, based on joint use of different kinds of geophysical and geological data, are particularly appreciated.

Geological fieldwork and stratigraphic analysis are the main sources of data on which most studies in volcanology are based. This session aims to be a forum for discussion among researchers involved in field volcanic studies finalized to understand the behavior of volcanoes and their future activity, to quantify volcanic processes and their associated hazards, and to provide input datasets for physical and mathematical modelling as well as for palaeoclimatic and chronological studies. We promote the presentation of multidisciplinary studies integrating geological field-based and various dating methods (radiocarbon, paleomagnetic, Ar/Ar, K/Ar, etc), as well as the 3D visualization of geological data and their extension and extrapolation in depth deriving from the superficial geological survey, shallow and deep cores, and various geophysical techniques. Geological maps of volcanic areas are welcome as tools for hazard evaluation and decision-making processes on territorial management and disaster risk reduction, for resource-exploration, and for land-planning and resource-management, including the cultural exploitation of the territory. Moreover, special attention will be given to the study of distal tephra layers in marine and terrestrial sedimentary archives as independent tools for dating and correlating Quaternary stratigraphic successions and synchronising palaeo-climatic archives in different sectors of a basin, and to investigate the effects of past (and present) volcanic ash dispersal on the environment and the response of civilizations to volcanic eruptions with palaeo-ecological, environmental and archaeological applications. The final purpose of this session is to stress the importance of volcanic field studies and tephrostratigraphy as the main sources of data to quantify volcanic processes and their impact on the human and environments.

The accurate digital reconstruction of morphologies in volcanic areas and high-resolution optical imagery are fundamental for studying and modelling natural phenomena generated directly or indirectly by volcanic and volcano-tectonic activity (e.g. lava flows, pyroclastic flows, lahars, tephra fall-out deposition, faulting processes, landslide detachment zones, rift zones and caldera subsidence). The morphometric analyses on high-resolution topographies can become essential tools for volcanic hazard and risk assessment, especially in populated areas. Among the innovative techniques UAVs photogrammetry have not only become indispensable and versatile tools to remotely study volcanic processes, but also result an important tool for the updating of volcanic topographies, filling a gap in resolution between satellite and ground observations. In addition, UAVs meet the need to increase safety for observers while accessing dangerous and/or inaccessible areas, which has prompted a rapid expansion in the development of new methods and miniaturized geophysical instruments in the last decade.
In order to inspire a wide range of discussions regarding methods to reconstruct high-resolution topographies in volcanic areas, this session welcomes contributions based on standard Geomatics disciplines (Airborne and Terrestrial LIDAR, Aerial and Satellite Stereo Photogrammetry with Multispectral Optical and IR data) and UAV technologies applied to several research fields, including: i) 3D high-resolution terrain reconstruction using optical (Structure from Motion), laser and radar imagery techniques; ii) terrain analysis with hyperspectral or thermal imagery; iii) collecting samples such as gas and ash; iv) 3D model analysis, visualization and derived outreach activity.

In volcanoes, the evolution of geophysical data acquisition systems has enabled increasing both quality and quantity of acquired information. Analysis, processing and interpretation of such information can allow detecting unrest and identifying precursors that portend eruptions. However, volcanic activities worldwide still present significant challenges for the knowledge of the structure and dynamics of volcanoes. In recent years, thanks to rapid technological advances, volcano observatories routinely collect vast amount of multi-parametric data (such as seismic, infrasonic, GPS and DInSAR ground deformation, gravity measurements). For this reason, processing and integration of multi-parametric, proximal and remote sensing dataset is crucial for understanding the volcanic processes, increasing the interpretative capacity of the observed volcanic phenomena. In this session, we welcome contributions focused on advances in geophysical signal processing, Data Mining, Machine Learning, Big Data, numerical (analytical and Finite Element) modelling and tools for improved volcano monitoring. Accordingly, the evaluation of the anticipatory elements of potential volcanic activity and its evolution is relevant to understanding and reducing the impact on the populations that live near the volcanoes and on the territory itself. This session is sponsored by the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement No 798480.

The understanding of the interplay between complex magmatic processes and volcanoes structures is a primary task for volcanological researches. The complexities of structures and deposits are evidence of the eruptive sequences and history and testify the preferred way for rising of magmatic and hydrothermal fluids, and the possible areas of magma storage and its movement. Moreover, multi-vent volcanoes are prone to the evolution through time of the magma accumulation zone, conduit/branch and ultimately of vents. By integrating physical and geological knowledge’s, it could be possible to reach a reliable definition of the volcanic structures, even in terms of steadiness or temporary modifications, which can concur to build a rigorous model of evolution of the system, as a fundamental tool to formulate possible future scenarios. We invite researchers conducting studies that span from geophysics to petrology, laboratory, and field experiment aiming to shed light in the plumbing system structure, at different scales, from surface to several km, and the eruptive history. Particularly, we welcome researches and monitoring methodologies based on multi-parametric datasets that address how the plumbing system is in causality relationship with volcano dynamics, as well as examples of how an enhanced knowledge of volcanic structures can improve assessment of the volcanic hazard.
S6 - Mechanisms, rates, and timescales of processes leading the triggering and evolution of volcanic eruptions Open or Close
- Marisa Giuffrida (UniCt)
- Silvia Massaro (INGV-BO)
- Maurizio Petrelli (UniPg)
- Roberto Sulpizio (UniBa)
The eruptions are typically the results of complex dynamics, as several chemical and physical mechanisms may act simultaneously at different rates and timescales. These include variations in the dynamics of fluid transfer, magma influx and rejuvenation, volatile exsolution and/or fragmentation during ascent, changes in local and far-field stress, or geometrical evolution of the conduit feeding system. The interplay among such different mechanisms generates complex evolutions in the feeding system of a volcano, and the resulting volcanic activity is often unpredictable. Examples of complex eruptive behaviors characterized by patterns of cyclicity and/or alternating eruptive styles (e.g. explosive vs. effusive) were described at a global scale. However, how the timing of magma chamber and conduit dynamics controls the eruptive behaviors is still far from a satisfactorily understood. For this reason, analyzing and modeling any temporal variations within the magma-chamber-conduit system before and during the volcanic activity is fundamental to understand eruptive dynamics, to evaluate current hazards, and investigate future scenarios. This session welcomes contributions addressing rates and timescales of processes that are related to the development and the evolution of volcanic phenomena. The characterization of triggering mechanisms, cyclic eruptive activities, and eruptive style transitions, investigated by using either single parameter or multi-parametric approaches, are the main aim of the session. The expected contributions may cover a broad range of investigations, including experimental, analytical, numerical, geophysical and field-based studies, as well as interdisciplinary approaches probing mechanisms and timescales of volcanic phenomena.
S7 - The nature of the mantle: geochemical and mineralogical composition versus petrological processes Open or Close
- Alessandra Correale (INGV-PA)
- Vincenzo Stagno (UniRM1)
- Costanza Bonadiman (UniFe)
The knowledge of the petrological and geochemical features of the mantle and the whole dynamics that control them is necessary to constrain the volcanic activity through space and time. The architecture of volcanism ultimately depends on the geochemical budget of the magma source, the initial ratio of volatile/lithophile elements, the rheology of magmas and how these change during ascent with respect to the chemical composition of magmas. This can be explored, directly by investigating mantle xenoliths, indirectly by examining the more primitive products from volcanic activity and experimentally by investigating the chemical and physical composition of magmas at pressures and temperatures representative of the mantle rock source. In this session, we encourage contributions aimed to constrain the heterogeneity of the Earth’s mantle in terms of mineralogical, petrological and geochemical composition. Studies that address the temporal evolution of the mantle heterogeneities are also welcome.

Explosive eruptions are among the most hazardous natural phenomena affecting society and environment. From low to high-level of eruptive styles, explosive activity may produce and disperse great amount of volcanic ash and gas that can significantly impact all the human activity and everyday life (e.g. aviation traffic, road network, human and animal health and vegetation). Over the last 15 years, the understanding of eruptive mechanisms and impacts of explosive eruptions has improved thanks to technology advance on remote sensing systems and the availability of new methodologies allowing investigating simultaneously of ash particles and observing gas emission at high frequency.
In this session, contributes on development and application of novel remote sensing systems, new/improved retrieval and validation strategies for characterizing explosive eruptions, quantification of the deposits and the physic-chemical and textural features of the ash and degassing regime, are welcome.
We encourage contribution describing the monitoring activity of ash and gas injection in the atmosphere both form ground and satellite together with characterization of ash ground deposits, which represent the major future challenges with obvious benefits on the surveillance and the assessment of potential impact of the most active volcanic areas.

S11 - Volcanic and hydrothermal systems: from geochemical processes to monitoring activities Open or Close
- Marcello Liotta (INGV-PA)
- Orlando Vaselli (UniFI)
Science may have very strong implications for people living around geothermal emissions. The knowledge of the processes occurring in hydrothermal systems represents a good opportunity for the exploitation of geothermal resources, to carry out effective monitoring programs and to take responsible decisions. This is particularly true in the field of geochemistry. Fluids circulating in hydrothermal systems play a fundamental role in determining their physical properties and provide a unique opportunity for obtaining information on processes operating at depth. In light of this, the scientific community pays particular attention to thermal fluid emissions and their variations over time. The understanding of the processes governing the chemical and isotopic composition of hydrothermal fluids is fundamental for defining effective geochemical models.
We are seeking contributions from any geochemical approach to study hydrothermal systems and geothermal resources.
S12 - Campi Flegrei: inter-disciplinary approach to the study of a high-risk caldera Open or Close
- Claudia D’Oriano (INGV-PI)

- Ilenia Arienzo (INGV-OV)
- Rosella Nave (INGV-OV)
The Campi Flegrei caldera has been restless for decades, showing signs of activity that are hard to interpret and cannot be unequivocally ascribed to magmatic reawakening of the system. This makes it a very high risk site, as well as a very challenging scientific subject. Ongoing geochemical, petrological and geophysical studies have highlighted the need for a multi-disciplinary approach in order to provide valuable information for risk and hazard assessment. This session aims at integrating contributions that range from research on past eruptions, e.g. by means of field investigation and analyses of erupted products, to the collection and interpretation of monitoring data streams, to informed models for hazard assessment. Scientific results should also be translated into clear messages for the interested population, thus improving risk perception and societal resilience. We believe that the integration of science and societal challenges, with a specific focus on Campi Flegrei, will spark interesting discussion for the benefit of both.

The July 3rd and August 28th 2019 paroxysms of Stromboli volcano are among the best monitored eruptions of the last decades, thanks to a capillary monitoring system covering numerous aspects of pre-eruptive and eruptive phenomena with visual, geophysical and geochemical parameters. The eruptions produced a few km-high eruption columns, huge tephra fallout and pyroclastic currents triggering extensive fires, and moderate tsunami wave.
In this session, we ask for contributions that cover the different aspects of the recent paroxysmal activity at Stromboli, i.e., eruption chronology and description, analysis of the tephra deposits, petrological studies, data analysis of geophysical and geochemical monitoring networks, tsunami dynamics, and flank instability.
Volcanological/petrological analysis, combined with the dense monitoring data, is offering a unique opportunity to expand our knowledge on explosive paroxysms, and is providing an unprecedented chance to test our capability to predict paroxysmal events. The goal of the session is to bring together the scientific community for encouraging debate on the eruptive mechanisms that control Stromboli paroxysms and on the identification of new models/monitoring strategies for mitigating the hazard associated to these volcanic phenomena.
S14 - From multi-hazards assessment to risk reduction in volcanic areas: how scientists and decision makers cooperate for future crisis management Open or Close
- Raffaele Azzaro (INGV-OE)
- Chiara Cristiani (DPC)
Volcanic hazard assessment is a multidisciplinary matter, particularly in Italy, where densely urbanised areas are exposed to different destructive phenomena. Lava flows destroying lifelines as well as cultivated and inhabited zones, volcano-tectonic earthquakes damaging buildings and infrastructures, ash fallout causing problems for human health and air traffic are the most frequent hazards. However, also pyroclastic flows and landslides potentially triggering tsunamis, represent possible, but less frequent, devastating hazards. Over the last decades, many studies have been aimed at specific hazards separately, but no integrated assessment has been produced.
History has shown that a successful volcanic crisis management strongly correlates with proactive risk reduction policies that derive only from knowledge of hazards. Hence, cooperation between scientists and Civil Protection is a continuous process, which needs to be based on solid and shared communication protocols, from hazard assessment to emergency management. This session is intended to promote ideas, methods and applications spanning from multi-hazard to risk assessment in volcanic areas, also considering case studies worldwide. We also welcome contributions presenting innovative strategies for integrating them and improve communication processes to increase awareness and preparedness on volcanic risk.

More than 75% of volcanic activity on Earth occurs underwater. Nevertheless, submerged volcanism remains almost under-explored; it’s a real challenge to directly observe volcanic eruptive processes beneath ocean surface. Nowadays advances in submarine volcanism have been made thanks to new technologies: high-resolution bathymetric and geophysical data are the key to develop: 1) seafloor bathymetries (to map volcanic structures and deposits), to identify edifice evolution, to understand eruptive style and secondary sedimentary processes; 2) geological models about volcanic structure and feeding system. Furthermore, hydrothermal fluid emissions analysis, with dragged samples, partially allow identification of magma properties and compositional variation. Although it is rare to witness an underwater eruption, seafloor volcanic activity becomes a problem when occurs not far offshore in shallower waters representing a real hazard to islands and coastal communities. Therefore, collecting information about underwater volcanic edifices is essential for risk assessment. We strongly believe that only a multidisciplinary approach can overcome the difficulties of describing accurately what happens below the surface. Therefore, the proposed session aims to gather researchers from multiple disciplines exploring the multiple aspects of underwater studies, to propose and show new approaches, the so-far achieved results and on-going works. The joined discussion of all these aspects can positively affect our knowledge of submarine volcanic activity.

The volcanological science presents itself as a strongly interdisciplinary discipline already in the vision of Alfred Rittmann developed during the course of the twentieth century. Current technology allows us to investigate volcanic phenomena by acquiring more and more data from different archives that make their processing and integration increasingly complex. Over time, hypotheses and theories alternate to better interpret the data collected. The study of the relationships between eruptions and human communities, together with the social, economic and urban consequences they determine, embraces numerous disciplines ranging from volcanology, archeology, anthropology, sociology and history. Nevertheless interdisciplinary studies between these disciplines in the volcanological framework are extremely limited both for the lack of a common language and for purely cultural reasons. Among the other interdisciplinary studies, a fruitful exchange of information between volcanologists and archaeologists and best integration of data of these two disciplines will be very welcome.
The main purpose of this session is to stimulate highly innovative and interdisciplinary approaches aimed at studying the history of volcanology and the interaction between eruptive phenomena and the communities that have interacted through time with volcanic phenomena, and also to improve the assessment of volcanic hazard and risks.
S17 - Landscapes and Geo-Cultural Heritage in volcanic areas: a great chance for the management of geosites and the volcanological education Open or Close

- Rosella Nave (INGV-OV)
- Marco Viccaro (UniCt, INGV-OE)
Landscapes and geo-cultural sites in volcanic areas have great potential for a sustainable development through geo-tourism. Indeed, these areas are worldwide source of unique scientific information and/or exclusive sites of cultural aspects often deriving from a long history of interaction between volcanoes and human communities. In many cases, however, these areas are increasingly being recognized as critical sites to preserve or pose questions about the best way to make aware visitors about volcanic hazards and to ensure minimization of risks. This means that conservation and valorization of these areas pass through an appropriate scientific knowledge as guarantee for the best presentation and dissemination of Geo-Cultural Heritage as well as through accurate programs for the risk management ensuring safety and security of visitors. In this session, we expect works addressing themes of Geo-Cultural Heritage (sites, objects, instruments, remains, memories, narratives, indigenous knowledge), volcano geo-tourism, education and outreach, which are aimed at promoting an exchange of information and experiences between organizations and people responsible for managing and/or working in volcanic areas (protected, such as parks, or not), and for sharing knowledge regarding experiences in geo-tourism, management of sites, pedagogy of volcanology at any level (primary, secondary, tertiary education) and outreach.
