Quantitative Forecasting of Volcanic Ashfall Prior to the Onset of Vulcanian Eruption by Combining Transport and Dispersion Simulation with Ground Deformation Observation at Sakurajima Volcano, Japan

Journal of Disaster Research
The Sakurajima Volcano has experienced repeated Vulcanian eruptions since 1955 for a period of 69 years. We propose a forecasting system for volcanic ashfall prior to the onset of eruptions based on monitoring ground deformation.

Eruption style transition during the 2017–2018 eruptive activity at the Shinmoedake volcano, Kirishima, Japan: surface phenomena and eruptive products

Earth, Planets and Space, 2023
Recent eruptions of the Shinmoedake volcano, Japan, have provided a valuable opportunity to investigate the transition between explosive and effusive eruptions. In October 2017, phreatic/phreatomagmatic explosions occurred.

Magmatic Processes at La Soufrière de Guadeloupe: Insights From Crystal Studies and Diffusion Timescales for Eruption Onset

Frontiers in Earth Science, 2021
Signals of volcanic unrest do not usually provide insights into the timing, size and style of future eruptions, but detailed analysis of past eruptions may uncover patterns that can be used to understand future eruptive behavior.
