Summary: The viscosity of magma strongly influences the style and hazard potential of a volcanic eruption. The unexpected 2018 eruption of Kilauea Volcano in Hawai'i demonstrated significant variability in erupted lavas, leading to unpredictable effusion rates and explosivity. Seismic and magma rheology analysis revealed a 90-degree local stress-field rotation prior to the eruption, indicating the involvement of magma with heightened viscosity.

Summary: This study used seismic records to infer the migration of the dike in the lower East Rift Zone of the Kilauea volcano, finding that the migration is consistent with a logarithmic model connected to a feeding magma chamber. The results suggest that the dynamics of magma transfer can be monitored in real time through the combination of seismic data and physical models.

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: The accelerating growth of seismic unrest before eruptions has been observed at many volcanoes and utilized for eruption forecasts. However, there are still many eruptions for which no precursory unrest has been identified, even at well-monitored volcanoes. Here we present seismological evidence that the eruption preparation had been ongoing at the shallow depths beneath Shinmoe-dake for several months to a year.

Summary: In 2018, Kilauea volcano erupted causing caldera collapse after a decade of basalt eruption. However, less than 2.5 years later, Kilauea erupted again. Analysis of magma surges and Global Positioning System data suggests that the pressure condition required to bring magma to the surface was met at the onset of the 2020 eruption.

Summary: A crucial aspect of managing a volcanic crisis is the ability of volcanologists to quickly detect an impending eruption. This study focuses on identifying different states of active volcanoes using monitoring data and highlights the importance of recognizing the state of impending eruption for timely forecasts. Applying this rationale to active volcanoes in densely populated areas demonstrates its feasibility and significance in eruption forecasting.

Summary: Analyzing the changes in physical properties before a volcanic eruption, we identified potential premonitory signals. In particular, we observed a 0.27% decrease in velocity 17 days before the eruption at stations located beneath the north-eastern sector of the volcano. This velocity change may be attributed to dilation caused by an earthquake and degassing of fluids in the rock.

Summary: Forecasting the style and chronology of volcanic eruptions is a complex issue that has received less attention compared to forecasting the onset and magnitude. This study develops a global data set of coded eruption phases and examines whether analog-based strategies can improve forecasting performance. The findings suggest that limiting the analog set based on volcano morphology and composition is not significantly more informative than using the entire data set. However, dynamically adjusting the data limits based on observed phases may provide some utility, and non-analog models can outperform the entire data set at the individual volcano level if the target volcano has unique behavior and sufficient record of phased eruptions.

Summary: Volcanic eruptions can trigger tsunamis, causing significant damage to coastal communities and infrastructure. This study uses seismic data to analyze the movement of the Kolumbo submarine volcano and the mechanisms behind volcanic tsunamis. The research shows that assessing submarine flank movements is critical for early warning of volcanogenic tsunamis.

Summary: Submarine volcanic activity releases gases and metals, affecting biogeochemical cycles and ecosystems. This study investigates the changes in water column above the submarine volcano after the eruption. The findings reveal that the volcanic activity influences dissolved gas concentrations, trace metal concentrations, and water acidity. The water column environment shows resilience and returns to a steady state after the main eruptive event.

Summary: This paper presents a set of calibration procedures for numerical models based on reference deposits or the distribution of runout distance or inundation area of pyroclastic density currents (PDCs). Various metrics can be used to compare the model results with the reference, allowing for scenario-based hazard assessments. Calibrations based on runout distance or inundation area can construct probabilistic hazard maps.

Summary: This paper analyzes earthquake and eruptive catalogs from 1800 to 2018 to quantify the impact of flank eruptions on earthquake frequency. The results show that the probability of major earthquakes increases 5-10 times after the onset of flank eruptions and this effect lasts for 30-45 days. Different volcano-tectonic systems have different relationships.

Summary: This study used an agent-based epidemiological model to analyze the transmission of SARS-CoV-2 in primary school classrooms and evaluated the effectiveness of different control strategies. The study found that testing-based surveillance is more effective than bubble quarantine in reducing transmission and avoiding student absences, and maintaining reduced contact rates within the classroom has a significant benefit for controlling the spread of COVID-19 in school settings.

Summary: The ice sheets on Antarctica and Greenland have significant uncertainties and potential contributions to future sea level rise. The dominant sources of uncertainty in 21st-century projections are surface melting in Greenland and ice dynamics in West Antarctica. In the 22nd century, the dominant drivers of uncertainty shift to ice dynamics in East Antarctica. These findings highlight the key processes and factors that need to be addressed to reduce uncertainties in ice sheet projections.

Summary: This study characterizes the morphology of intermediate to silicic lava flows and investigates their relationship with thickness distribution, pre-surface slope, composition, and rheology. It is found that the pre-eruptive slope, effusion rate, and viscosity of the lava play important roles in determining the lava flow morphology. Four main types of lava flows are identified based on the analysis of 49 intermediate to silicic lava flows.

Summary: This study presents a probabilistic hazard assessment for the San Salvador volcanic complex, focusing on eruption scenarios for tephra fallout and pyroclastic density currents. Numerical modeling reveals that thick tephra layers can be deposited in the metropolitan area of San Salvador during Plinian eruptions, but the sedimentation probability is reduced during the rainy season. Violent Strombolian eruptions have low probabilities of depositing significant tephra mass loads in San Salvador city. PDCs during large-scale Plinian eruptions can invade surrounding areas, including San Salvador city, while sub-Plinian eruption columns have low inundation probabilities for the city.

Summary: During the eruption sequence of Guagua Pichincha volcano in Ecuador from 1999-2001, rock samples provided information about magma storage, ascent, decompression, degassing, repressurization, and regassing prior to eruption. The melt inclusions revealed high water and carbon dioxide contents, while mineral crystals exhibited variations in their compositions. The seismic activity and surface tilt changes indicated a sudden evacuation of magma in the shallow conduit. These findings are significant for understanding volcanic eruptions.

Summary: This study presents a method for calculating the probability of a distal geographic location being impacted by a pyroclastic density current (PDC) of a given size. The analysis takes into account key uncertainties associated with the modeling. By evaluating the minimum volume and mass of a PDC generated at the Aso caldera in Japan, the researchers assess the likelihood of different infrastructure sites being affected. The results show that the probability of a catastrophic eruption reaching the marker sites is significant, depending on the uncertainty in the erupted mass and the direction of the marker site.
