Summary: In this study, the authors used the ICON-ART model to investigate the aging of volcanic ash aerosols and the production of sulfates following the 2021 La Soufriere eruption. They found that online coupling of the model was essential for accurately simulating the evolution of volcanic emissions and plume development. The simulated aerosol aging showed good agreement with observations from remote sensing instruments.

Summary: This study analyzes the mercury concentrations in 227 bulk ash samples from the Mount Spurr (1992), Redoubt Volcano (2009), and Augustine Volcano (2006) eruptions. The results show that there is no significant difference in mercury concentrations based on distance or discrete eruptive events, but there is a significant difference among different volcanic sources. It is also found that previous approaches to estimate volcanic total mercury emissions underestimate the mercury emitted in explosive events.

Summary: Researchers studied the characteristics of tsunamis in Lingding Bay and its surrounding areas by analyzing records from tide gauges and meteorological stations. They found Lamb waves in the bay approximately 8, 44, and 80 hours after the volcanic eruption. The first and second tsunami waves arrived around 11 and 45-47 hours after the eruption, respectively, which was consistent with the arrival time of Lamb waves. They also analyzed the frequency characteristics of the sea level records and found that the two tsunami waves had similar source spectra.

Summary: The paper discusses the aerosol measurements taken during the volcanic eruption of Cumbre Vieja in La Palma Island, showing that the height of the volcanic plume varied significantly and steadily increased after the eruption started. The ash mass concentration was evaluated using a polarized lidar instrument, with the highest estimated concentration reaching 800-3200μg m(-3).

Summary: This study assesses the potential impacts of volcanic ash from the 2021 Tajogaite eruption on human health. The findings suggest that fluoride concentration in the ash may pose a potential health risk for water supply and children's drinking water.

Summary: On 15 January 2022, a volcanic eruption in Tonga resulted in globally observed tsunami waves. Through Vespa analysis, the source of the later phases was estimated and a new numerical scheme was proposed to reproduce them. The study found that small atmospheric waves triggered the large later tsunamis.

Summary: This article presents a method for classifying the electrical activity during explosive volcanic eruptions into vent discharges and lightning. The method uses logistic regression and has a high accuracy rate, making it useful for determining the occurrence of explosive eruptions.

Summary: The intense volcanic and seismic activity at Kilauea volcano, Hawaii in 2018 provided an opportunity to understand the characteristics and driving forces of volcano earthquake clusters. Analysis revealed two clustering modes with different characteristics and seismic activity influenced by deformation rates within the caldera.

Summary: On 15 January 2022, the eruption of the Hunga-Tonga volcano in the South Pacific Ocean resulted in a violent underwater explosion, causing tsunami waves and atmospheric pressure disturbances. Numerical simulation shows an excellent agreement between the simulated wave arrival time and observations.

Summary: Research shows that volcanic eruptions in Iceland are generally preceded by an increase in tremor levels, which do not have a clear onset like earthquakes. During the Eyjafjallajokull summit eruption, volcanic tremor frequencies ranged between 0.5 and 10 Hz, and the power variations of the tremor with distance from the eruption site indicate that surface waves dominate the tremor waveform content in the 0.5-2 Hz frequency range. The pattern of radiated wave energy from the tremor source varied with time, defining ten different epochs during the eruption.

Summary: The presence of fluoride-bearing compounds in volcanic ash poses significant environmental and health hazards. Research suggests the existence of silicon hexafluoride salts, particularly Na2SiF6, in magmatic ash, which affects the F- concentration, acidity, and dissolved silicon isotope values. This highlights the important role of Na2SiF6 in modulating the environmental and health effects of ash emissions from fluorine-rich magmatic eruptions.

Summary: The study assesses the skill and limitations of the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME) in simulating the dispersion of sulfur dioxide (SO2) cloud from the 2019 Raikoke volcanic eruption. The model accurately simulates the horizontal extent of the SO2 cloud during the first 2-3 weeks after the eruption, but struggles to capture the highest magnitude vertical column density (VCD) regions within the observed volcanic cloud.

Summary: Volcanic eruptions in Iceland are often preceded by an increase in tremor levels, which vary in frequency and can be influenced by different factors. The source of the tremors may be shallow, less than about 1 km deep, and the pattern of wave energy radiated from the tremor source changes over time.

Summary: In this study, seismic reflection and P-wave tomography datasets were integrated with computed tomography-derived sedimentological analyses to estimate the volume of the iconic Minoan eruption. The results revealed a total eruption volume of 34.5 +/- 6.8 km(3), with different proportions of tephra fall deposits, ignimbrites, intra-caldera deposits, and lithics. These volume estimates were consistent with an independent caldera collapse reconstruction. The findings demonstrate the importance of complementary geophysical and sedimentological datasets for reliable eruption volume estimates and volcanic hazard assessments.
