Here, I have downloaded the NASA ASTER data for Stromboli volcano from 09:51:36 UTC. Also, i have examined the webcams from INGV (all four) from 09:51:00 UTC and also the University of Firenze FLIR webcam, captured every 4 seconds from 09:50 - 09:52 UTC
The ASTER data shows a TIR signal around 100 C, this is close to saturation temperature for these channels. The RGB (visible) data shows partly cloudy volcano, with an evidence Scorro del Fuoco. Also note in the TIR, the warmer signal at the ocean entry, and in the RGB the different color of the ocean surface. This is likely due to material entering the ocean at the end of the Scorro del Fuoco.
The INGV webcams captured at 09:51 UTC, show the hot summit and flows down the Scorro del Fuoco. The University of Firenze FLIR shows an event at 09:50:24 UTC, just over an minute before the ASTER overpass. This emphasizes the need for high frequency data to detect all the events now occurring at Stromboli and any active volcano. The INGV cameras every 3 minutes, have a temporal frequency between capture that is too long for these short lived events.
