Abstract: Integration of multi-sensor, multi-platform remotely sensed data is an effective methodology for monitoring active volcanoes as it ensures a constant data flow, which is needed for repeated eruptive events in brief intervals. It allows broad observation of the eruptive scenario and quantification of the erupted products. We integrated remote sensing data, through GIS software, to map the lava flows of Etna, one of the most active volcanoes in the world. Between July 2019 and December 2023, Etna gave rise to seventy-five eruptive events, mainly from the summit craters, emplacing one hundred lava flows. We updated Etna's 1999-2019 map, with the most recent eruptive products, mapping ninety-three lava flows out of the one hundred-five. For cartographic simplicity, summit flows are grouped by year or eruptive cycle, while flank flows are distinguished by date. To better display the products and highlight the mapping process, we added twenty-one detailed maps to the main map.The graphical abstract depicts a funnel with three circles representing the analyzed data. Its bottom portion displays Etna’s geological map of the last three years, showing the spatial distribution of lava flows using different colors for the eruption dates or eruptive cycles. The legend to the left consists of colored rectangles corresponding to the dates of the lava flows shown on the map. Additionally, there are twenty-one detailed maps, each showing two to four lava flow units. All the lava flow maps are overlaid to a shaded relief image that helps to understand the morphology of Etna.
