The IMPROVE field experiment on Mount Etna took place from July 23 to August 2, 2023. All of the IMPROVE ESRs actively participated in the experiment, which involved deploying instruments, periodically checking their functionality, downloading data and starting their analysis, and finally dimantling the instrumentation. The organization of the experiment primarily involved personnel from INGV – Etnean Observatory, with secondary support from personnel from INGV Pisa. The experiment mainly focused on two aspects of the shallow Mount Etna dynamics: its degassing and the movement of magma.

The instruments deployed during the experiment included: two broadband seismic stations, four high frequency GNSS receivers, one clinometer and one diffused degassing measurement device, two seismic arrays with ~100 nodes, an about 1 km long fibre optic and dedicated acquisition system, and finally a high speed visible and an infrared camera plus microphone positioned on the crater rim. This network worked together with the permanent monitoring network of the INGV Etna Observatory, consisting of about 200 multi-parametric instruments. The collected data provide the basis for the analyses by six ESRs who are developing their PhD on Mount Etna. Initial analyses triggered vivid discussion, particularly in the context of numerical solutions for the dynamics of magma convection in underground volcanic systems.

The experiment also included a two-day field trip aimed at providing the ESRs with an understanding of the structural complexities that characterize an active volcano. Specifically, the trip focused on the major structures along the North-East and East volcano flanks of Mount Etna and how these structures impact the setup of a volcano monitoring system.

Nicolosi (Mount Etna), Italy – July 24 – 28, 2023

The Etna IMPROVE school took place from July 24th to July 28th, 2023, in Nicolosi, on the flank of Mount Etna. It was held at the INGV building, as well as in the nearby premises of the conference center of the Nicolosi municipality, which were generously made available. The school was attended by a total of 30 students, consisting of the 15 IMPROVE ESRs and an additional 15 external students who were selected through an open call from among nearly 40 applications received.

The students were trained in the use of sophisticated software, representing the culmination of several years of research and technological development at INGV and partner universities. The ultimate goal was to provide the students with as much practical training as possible in “multiparametric volcano monitoring, data processing, analysis, and modeling”. The first day was dedicated to lessons and exercises on volcano deformation, complemented by a demonstration of the EPOS portal (https://www.epos-eu.org/dataportal) for accessing multi-parametric data from Earth observation systems, including data from volcano observatories. The second day was dedicated to volcano degassing, the fourth day focused on volcano seismicity, and the fifth day involved a simulation exercise. During the exercise the different groups of students simulated a real volcano observatory dealing with a volcanic crisis, and had to use the instruments and tools provided and taught during the school to respond to the crisis. In the late afternoon, each group presented their results together with different statements prepared by them for communication to civil protection authorities and to the media, with ample discussion with senior researcher, particularly those from the INGV Etna Volcano Observatory. The third day of the school was dedicated to the field trip to Mount Etna. The trip was led by Boris Behncke from the Etna Observatory, who presented with engaging and compelling attitude the history and evolution of the volcano, adding stories and anecdotes about recent and past eruptions as well as about volcanologists who worked on the volcano.

The IMPROVE Open Day took place on May 17, 2023, at the Foy Centre in Carlingford, Ireland. Its goal was to engage and spark interest among various audiences, including primary and secondary school students, as well as the local community. The audience was involved in experiments led by IMPROVE ERSs, alongside other PhD students joining them, covering various aspects of volcanology and seismology.

The children generated their own earthquake by jumping on the floor and then observed the corresponding seismogram on a screen. Moreover, they had the opportunity to view live earthquakes from around the world on the Raspberry Shake website. Two trays of jelly and premade ‘buildings’ constructed from sticks and marshmallows were used to mimic various earthquake-resistant structures.

Slinkys and ropes were utilized to illustrate various types of seismic waves and their propagation, while different waveforms on the spectrogram were displayed using a keyboard and a guitar.

The children also observed a cross-section of a volcano created using a fish tank and various other materials designed to represent the internal composition of a volcano. They were able to examine several volcanic specimens, appreciating the density differences between tuff and basalt samples and learning about the magnetism associated with specific rocks. The rheology of magma was explained using Oreo cookies, and volcanoes were created using an old glass bottle, expanding foam, and paint. The eruption was instead simulated using vinegar and baking soda. An experiment was set up with water, ketchup, and honey in plastic cups, and air was blown into them using a straw to demonstrate the different viscosities of various fluids. A CO2 meter was also introduced to simulate the increasing CO2 levels during an eruption. Finally, the children witnessed an outdoor volcano eruption: a traffic cone was transformed into a real-life volcano. Inside the cone, Pepsi and Mentos were mixed together to create a highly explosive eruption!

The day attracted a total of 213 primary school students and members of the public. There were 182 students from two primary schools, along with 22 teachers and assistants in attendance. The feedback from the participants was extremely positive. The children found the day to be a fun and educational experience, and the teachers and staff appreciated the organization and management of the Volcano Open Day. Overall, it was a highly successful and beneficial public outreach event.

On May 14-20, 2023, the third IMPROVE Network School was held in Carlingford, Ireland, under the leadership and organization of partner DIAS. The school was attended by 23 young researchers, including 14 IMPROVE ESRs and 9 other participants, coming from 10 different countries in Europe.

The school focused on geophysical data inversion and numerical modeling, by exploring both theoretical and practical aspects of these techniques. Examples from seismic and acoustic source estimations, volcano deformation, and volcano imagery using seismology and magneto-tellurics were used. The school also compared physics-based and data-driven inversion approaches, as well as new hybrid inversion methods incorporating deep learning and physical laws. Additional soft-skill elements of training included project management, research leadership, and effective communication.

A field trip to the Giant’s Causeway, on the coast of Northern Ireland, was organized to observe interlocking basalt columns. The field trip was led by Dr Michael J. Simms, Senior Curator of Geology at National Museums Northern Ireland, and Dr Mark Cooper, Chief Geologist at the Geological Survey of Northern Ireland (GSNI).

On the 17th of May an IMPROVE Open day was held in the Foy Centre in Carlingford, engaging primary and secondary school students as well as the local community. The day attracted a total of 213 primary school students, their teachers, and members of the public. The school students presented experiments and measurement in seismology, rock magnetics, buoyancy, wave propagation, using a variety of materials from natural rocks to different fluids. The teachers and staff commented on how organized and well run the Volcano Open day was. Overall, it was a highly successful and beneficial public outreach event.

On 21-23 January 2023 at ISTerre, Grenoble (France) took place the first IMPROVE Specialized Short Course. The course was organized an managed by organized by Stéphane Garambois and Jean Vandemeulebrouck. It focused on the new techniques developed in seismology (ambient noise, DAS, covariance techniques), on seismic tomography, on the acquisition and processing of geophysical data from the European data centers and on complementary imaging methods, magnetic, electrical and electromagnetic, applicable to volcanoes and geothermal areas. 9 of the 15 ESRs from IMPROVE project attended this course together with further 8 PhD students from the doctoral school STEP (Sciences de la Terre, de l’Environnement et des Planètes) of University Grenoble Alpes

27-29 March 2023

The Second Specialized Short Course on Volcano Geodesy was held at the School of Earth Sciences, University of Bristol (UK) at the end of March. It was organized by Prof. Joachim Gottsmann, and attended by 8 IMPROVE ESRs plus 8 external students.

The course focussed on techniques for monitoring volcano deformation, including ground-based and satellite-based methods, as well as on data interpretation using mathematical modeling and both forward and inverse approaches. The participants were introduced to increasingly complex approaches from analytical to numerical computation and analogue experiments of volcano deformation, and could analyse and test themselves the relevance of different assumptions on crustal mechanics and rheology in determining ground deformation at active volcanoes.
