This study aims to achieve two primary objectives. Firstly, it offers empirical evidence on the statistical dis tribution of inter-event times for lava fountains at Mt. Etna between 2011 and 2022, revealing that these times follow a power-law distribution, which supports the hypothesis that volcanic energy release exhibits dynam ics characteristic of Self-Organized Criticality (SOC) systems. Secondly, it introduces a modified version of the classic Bak-Tang-Wiesenfeld (BTW) model, specifically adapted to simulate the inter-event times of lava fountains in volcanic environments like Mt. Etna. Although the proposed model is straightforward and offers initial insights, it remains preliminary. Further development is needed to enhance its accuracy and extend its applicability to more complex volcanic systems
