At 12:17 p.m. another strong eruption occurred at Stromboli (Sicily). The explosion produced an ash cloud several kilometres high. Lava boulders even landed on the outer flank of the cone, about where the ascent route leaves the reed belt. On the side of Ginostra the vegetation burned to about 200 m height. A pyroclastic flow ran over Sciara del Fuoco. The eruption was announced shortly before by a significant increase in inflation. According to an initial assessment, the explosion was not quite as strong as the one on July 3. Nevertheless, the risk potential was very high. There have not yet been any reports of victims, but it is quite conceivable that there were.
