On 21 May 2023, a hidden eruption occurred at the Southeast Crater (SEC) of Etna (Italy); indeed, bad weather prevented its direct and remote observation. Tephra fell toward the southwest, and two lava flows propagated along the SEC's southern and eastern flanks. The monitoring system of the Istituto Nazionale di Geofisica e Vulcanologia testified to its occurrence. We analyzed the seismic and infrasound signals to constrain the temporal evolution of the fountain, which lasted about 5 h. We finally reached Etna's summit two weeks later and found an unexpected pyroclastic density current (PDC) deposit covering the southern lava flow at its middle portion. We performed unoccupied aerial system and field surveys to reconstruct in 3D the SEC, lava flows, and PDC deposits and to collect some samples. The data allowed for detailed mapping, quantification, and characterization of the products. The resulting lava flows and PDC deposit volumes were (1.54 ± 0.47) × 106 m3 and (1.30 ± 0.26) × 105 m3, respectively. We also analyzed ground-radar and satellite data to evaluate that the plume height ranges between 10 and 15 km. This work is a comprehensive analysis of the fieldwork, UAS, volcanic tremor, infrasound, radar, and satellite data. Our results increase awareness of the volcanic activity and potential dangers for visitors to Etna's summit area. [ABSTRACT FROM AUTHOR]

In this paper, we propose an update of the spatial probability map for flank eruptions from Etna (Italy), based on the distribution of the flank eruptive fissures that opened in the last 4000 years. The general procedure followed is to split the fissure dataset into training and testing subsets; then we build models on the training subset under different assumptions and test them on their likelihood of the testing subset. This allows selecting objectively the best models and assumptions. Furthermore, it allows testing whether (i) unavoidable incompleteness in the mapped fissures, and (ii) possible migration through time in the location of the flank activity, have an effect on the training models that can or cannot be neglected. We used different spatial models by exploiting different Kernel functions (Exponential, Cauchy, Uniform, and Gaussian), and calculated the degree of clustering of flank fissures in the training data. The results show that neither under-recording nor possible migration in time affect significantly the informativeness of the previous flank fissures in forecasting the location of the successive ones. Our study provides a canonical map of the spatial probability for future flank eruptions at Etna based on the location of flank fissures that opened in the last 4000 years. The map confirms a preferred location along a Northeast-to-South area, corresponding to the location of the most active rifts. It also shows that the Southern flank of the volcano, which is the most urbanized one, sits downhill of the largest cumulated-probability area for flank eruption. We also run sensitivity analyses to test the effect of (i) restricting the data to the most recent 400 years, and (ii) including the information on the unclamping stress induced on the mapped fissures by sources of deformation proposed in literature for recent eruptions of Etna. The results of the sensitivity analyses confirm the main features of the canonical map, and add information on the epistemic uncertainty attached to it. [ABSTRACT FROM AUTHOR]

The Virunga was established in November 2017 as a permanent Supersite with the aim of improving the geophysical scientific research and Geohazards assessment in support of Disaster Risk Reduction (DDR) in the Virunga Volcanic Province and the Lake Kivu basin. The CEOS guarantees a free access to Earth Observatory (EO) data, while the pool of collaboration built around the Supersite potentially supports the access to equipment for ground-based data collection and processing. From November 2017 to November 2019, in addition to implementing the Supersite; collaboration was built between the GVO and the world leading observatories and agencies, the free access to EO data with first steps towards collecting some ground-based data, training of some local scientists, and the adhesion to the Virunga Supersite of world top-level geoscientists in the field of active volcano monitoring and hazards assessment. The later allowed the assessment of volcanic hazards around Nyiragongo and Nyamulagira, which included the production of hazards maps for future volcanic eruptions management, the collection of ground-based data to produce Risk and Recovery mapping. On the evening of May 22nd 2021, Nyiragongo volcano suddenly erupted from three vents that opened along a system of fractures on the southern flanks of the volcano. Two major lava flows were produced with one having its direction toward Goma city. Fortunately, these lava flows stopped their run before reaching the densely populated areas, with one being only at ~1 km from the Goma international Airport. Still, the lava flows had already destroyed about 3,600 houses while another 1,000 were severely damaged causing at least 30,000 persons to be in the need of shelter and other humanitarian assistance. The volcanic eruption further caused the death of 38 persons, disrupted the water supply infrastructures in Goma and the surrounding: estimated 550,000 persons lost access to water. An intense seismic activity followed the eruption and persisted for ~2 weeks, and caused sever damages to houses and infrastructures such as roads, water and electricity networks. Furthermore, the earthquakes caused important ground deformation in Goma and Gisenyi cities, which brought the fear of magma rising and accumulating beneath Goma and Lake Kivu. This raised a scenario of a new eruption with active vents inside Goma city or Lake Kivu, and led local authorities to evacuate estimated 400,000 people. Virunga Supersite scientific team supported the response to the Nyiragongo 2021 volcanic crisis through data processing, which yielded the production of key information that was delivered to local authorities and supported the management of the volcanic and humanitarian crises. In September 2021 a new effusive activity began inside Nyiragongo main crater, along with a sustained seismic activity and ground deformation to the southern flank of the volcano. The fast renew of the activity denotes the strong and urgent need to starting prepare for the next Nyiragongo volcanic eruption; and the Virunga Supersite is willing to be part of this goal. This preparation strongly need an enhanced monitoring infrastructure that would permit follow up the complex Nyiragongo-Nyamulagira rift-zone volcanism, forecast the spatiotemporal extent of the next eruption which will reduce its impacts. Furthermore, a proper training of local scientists is part of the well properness to the next Nyiragongo crisis, which the Supersite has already started., {"references":["Balagizi C.M., G.
