    Description: Diffusive gradients in thin fi lms (DGT) have been tested in CO2-rich, metal-bearing fl uids from springs in the Campo de Calatrava region in Central Spain, to assess their applicability as a monitoring tool in onshore CO2 storage projects. These fi lms are capable of adsorbing metals and recording changes in their concentration in water, sediments, and soils. Considering that CO2 dissolution promotes metal solubilization and transport, the use of these fi lms could be valuable as a monitoring tool of early leakage. A number of DGT have been deployed in selected springs with constant metal concentration. The studied waters show high concentrations of Fe, as high as 1 × 104 μg·L–1, Ni, Co, Zn, Cu, and Mn. Comparing re-calculated metal concentration in DGT with metal water concentration, two different metal behaviors are observed: (i) metals with sorption consistent with the metal concentration (i.e. plotting close to the 1:1 line in a [Me]DGT: [Me]water plot), and (ii) metals with non–linear sorption, with some data showing metal enrichment in DGT compared with the concentration in water. Metals in the fi rst group include Fe, Mn, Co, Ni, and U, and metals in the second group are Zn, Pb, Cr, Cu, and Al. From this research, it is concluded that the metals in the fi rst group can be used to monitor potential leakage by using DGT, providing effective leakage detection even considering low variations of concentrations, episodic metal release, and reducing costs compared with conventional, periodic water sampling.

    Description: The dynamics driving an eruption play a crucial role in the impact volcanic activity has on the community at large. The interpretation of geophysical and geochemical changes heralding a volcanic unrest is a fundamental key to forecasting upcoming phenomena. However, the style and intensity of the eruption are difficult to predict, even in open-conduit volcanoes where eruptions can be relatively frequent. This is the case of Etna, in Italy, one of the most active basaltic volcanoes in the world. In 2021, fifty-two lava fountains arose from its Southeast Crater accompanied by lava emissions and ash fallout, which disrupted air and road traffic in numerous Sicilian municipalities. Lava fountains are just one of the typical eruptive styles of Etna. Strombolian activity and lava flows are also relatively frequent here, each with its own characteristics in terms of intensity and social impact. We developed a machine learning (ML) method for the analysis of the seismic data continuously acquired by the local stations of the Etna permanent seismic network, exploiting the spectral characteristics of the signal. Its design started from: i) the need to detect the volcanic hazard, and ii) provide timely and indicative information on possible eruptive scenarios to the Civil Protection and the Authorities. Besides the identification of anomalies in the data, which flag enhanced volcano dynamics in its early stages, we investigate on clues concerning the potential intensity level of eruptive phenomena. The method works in near real time and can effectively contribute to the multidisciplinary analysis of volcanic hazard.
    Description: This work was undertaken within the project IMPACT (A multidisciplinary Insight on the kinematics and dynamics of Magmatic Processes at Mt. Etna Aimed at identifying preCursor phenomena and developing early warning sysTems). IMPACT belongs to the Progetti Dipartimentali INGV [DIP7], https://progetti.ingv.it/index.php/it/progetti-dipartimentali/vulcani/impact#informazioni-sul-progetto.

    Description: Field-based classes in geological sciences are crucial components of geoscience education and research. Owing to the COVID-19 pandemic, such activities became problematic due to limitations such as travel restrictions and lockdown periods: this motivated the geoeducational community to tailor new ways to engage people in field activities. As a result, we adopted Immersive Virtual Reality as a tool to involve students, academics, and the lay public in field exploration, thus making geological exploration accessible also to people affected by permanent or temporary motor disabilities. In particular, we evaluated how users perceive the usefulness of this approach as applied to Earth Science learning and teaching, through nine outreach events, where a total of 459 participants were involved, with different ages and cultural backgrounds. The participants explored, in an immersive mode, four geological landscapes, defined as virtual geological environments, which have been reconstructed by cutting-edge, unmanned aerial system-based photogrammetry techniques. They include: Santorini (Greece), the North Volcanic Zone (Iceland), and Mt. Etna (Italy). After the exploration, each participant filled in an anonymous questionnaire. The results show that the majority would be willing to repeat the experience, and, most importantly, the majority of the students and Earth Science academics who took part in the navigation confirmed the usefulness of this technique for geo-education purposes. Our approach can be considered as a groundbreaking tool and an innovative democratic way to access information and experiences, as well as to promote inclusivity and accessibility in geo-education, while reducing travel costs, saving time, and decreasing the carbon footprint. This work has been carried out in the framework of the following projects: i) ACPR15T4_ 00098 “Agreement between the University of Milan Bicocca and the Cometa Consortium for the experimentation of cutting-edge interactive technologies for the improvement of science teaching and dissemination” of Italian Ministry of Education, University and Research (ARGO3D - https://argo3d.unimib.it/); ii) Erasmus+ Key Action 2 2017-1-UK01-KA203- 036719 “3DTeLC – Bringing the 3D-world into the classroom: a new approach to Teaching, Learning and Communicating the science of geohazards in terrestrial and marine environments” (http://3dtelc.lmv.uca.fr/; https://www.3dtelc.com/); iii) 2018 EGU Public Engagement Grants (https://www.egu.eu/outreach/peg/).
