Session 1.2 GNGTS 2024 dynamics. Using Google Earth Engine (GEE), we outlined each crater region and computed the contributon of each crater to the overall detected thermal anomalies; a circular area around each crater is considered, namely South-East (SE), North-East (NE), Bocca Nuova (BN) and Voragine (VOR). A period of intense eruptve actvity began on December 14, 2020, with the frst of 66 paroxysms producing several lava fows (Amato et. al., 2022), with the maximum area quantfed being 1,800,000 m2 on 18 December. It is noteworthy that all the craters show consistent increases in the areal coverage of thermal anomalies before the frst paroxysm (see Fig. 1), with NE and SE (see Fig. 2a-b ) startng in June 2020. Lately, since June 2022, the most actve crater has been BN. One of the most recent paroxysm events occurred on November 12, 2023, and was preceded by a net increase in thermal anomalies since October 16, 2023, when SE crater became actve. Fig. 1 Fig. 2 Stromboli is characterized by persistent explosive actvity that can sometmes escalate into more intense events, producing major explosions or paroxysmal events (Calvari et al., 2022, Giudicepietro et al., 2022). These events may lead to lava fows, as seen in October 2023 when a new eruptve actvity commenced (Fig. 3). This actvity was preceded by a steep increase in the
