Mechanism of the historical and the ongoing Vulcanian eruptions of Ebeko volcano, Northern Kuriles. [PDF]
Bull Volcanol, 2021 Ebeko is one of the most active volcanoes of the Kurile island arc, producing frequent mild Vulcanian explosions with eruption clouds up to 5 km high. The volcano poses a serious threat to the Severo-Kurilsk town with a population of around 2500 inhabitants, located at a distance of only 7 km on a fan of the volcano's laharic deposits.

Tephra segregation profiles based on disdrometer observations and tephra dispersal modeling: Vulcanian eruptions of Sakurajima volcano, Japan [PDF]
Earth, Planets and SpaceThe profile of tephra concentration along a volcanic plume (i.e., the tephra segregation profile) is an important source parameter for the simulation of tephra transport and deposition and thus for the tephra sedimentation load.

Sedimentation process of ashfall during a Vulcanian eruption as revealed by high-temporal-resolution grain size analysis and high-speed camera imaging [PDF]
Progress in Earth and Planetary Science, 2020 We here examined the sedimentation process of falling ash particles during a short-lived Vulcanian eruption at Sakurajima volcano, Japan, using high-speed camera imaging of airborne ash particles, as well as grain size analyses of ash samples collected ...

Insights into the sticking probability of volcanic ash particles from laboratory experiments [PDF]
Scientific Reports, 2023 Although the characterization of the sticking and aggregation probability is essential to the description of volcanic ash dispersal and sedimentation, there is still no general model describing the sticking probability of volcanic ash. Experiments of dry

Integrating hazard, exposure, vulnerability and resilience for risk and emergency management in a volcanic context: the ADVISE model [PDF]
Journal of Applied Volcanology, 2021 Risk assessments in volcanic contexts are complicated by the multi-hazard nature of both unrest and eruption phases, which frequently occur over a wide range of spatial and temporal scales.

Aerodynamic characteristics and genesis of aggregates at Sakurajima Volcano, Japan [PDF]
Scientific Reports, 2022 Aggregation of volcanic ash is known to significantly impact sedimentation from volcanic plumes. The study of particle aggregates during tephra fallout is crucial to increase our understanding of both ash aggregation and sedimentation.

Volcanic Eruption Forecasts From Accelerating Rates of Drumbeat Long‐Period Earthquakes [PDF]
Geophysical Research Letters, 2018 Accelerating rates of quasiperiodic “drumbeat” long‐period earthquakes (LPs) are commonly reported before eruptions at andesite and dacite volcanoes, and promise insights into the nature of fundamental preeruptive processes and improved eruption ...

Modeling Volcanic Eruption Parameters by Near-Source Internal Gravity Waves. [PDF]
Sci Rep, 2016 Volcanic explosions release large amounts of hot gas and ash into the atmosphere to form plumes rising several kilometers above eruptive vents, which can pose serious risk on human health and aviation also at several thousands of kilometers from the ...
