While this preliminary model provides initial insights into the dynamics of lava fountain recurrence, further refinements are necessary to improve its accuracy in capturing the observed variability in eruption inter-event times and its applicability to more complex volcanic systems.

摘要

This study investigates the statistical distribution of inter-event times for lava fountains at Mt. Etna (2011-2022), demonstrating a power-law scaling indicative of Self-Organized Criticality (SOC). Furthermore, a modified version of the Bak-Tang-Wiesenfeld (BTW) model, referred to as the Volcano Sandpile (VS) model, tailored to simulate these inter-event times is investigated. While this preliminary model provides initial insights into the dynamics of lava fountain recurrence, further refinements are necessary to improve its accuracy in capturing the observed variability in eruption inter-event times and its applicability to more complex volcanic systems.
