**3. Dataset and Methods**

Our work is based on the analysis of 2 satellite-based thermal datasets (provided by MODIS and SENTINEL 2 sensors, respectively) and 2 geophysical datasets, constituted by seismic and infrasonic signals recorded at ETN and MVT stations, respectively (Figure 1). Here, we summarize the methodology used to analyze these four sets of data in order to track the activity of the Etna volcano occurred between September and December 2018.
