Mount Stromboli, on a small island in the Tyrrhenian Sea, has been in almost continuous eruption for the past 2,000 years. Its activity is almost exclusively explosive, but lava flows do occur at times, most recently in 2014.

Looking at the animated SEVIRI Ash RGB product, 3 July, 14:00–23:45 UTC, (Figure 2), it is clear that the main eruption occurred some time between 14:30 and 14:45 UTC. There was one stronger episode of ash and SO2 ejection in the atmosphere, sensed by SEVIRI infrared channels, where the content spread in arch-like pattern that expanded and spread mainly in a south-easterly direction.

Initially both ash and SO2 were detected (Figure 1, top right, click to expand). After few hours most of the volcanic ash settled down and only the SO2 plume continued to spread into the following day.
