摘要：

Two paroxysmal explosions occurred at Stromboli volcano (Italy) on 8 and 24 November 2009. Analysis of recordings (from video-camera surveillance) indicates that each paroxysm consisted of multiple bursts from different vents. Field surveys, carried out within a few days after the two paroxysmal events, allowed us to gather crucial data on eruptive deposits and document morphological variations occurring at the source vents. Integration of video-analysis and field observations allowed making inferences on the eruptive dynamics of each explosive paroxysm. The 24 November event, in particular, erupted a larger volume and coarser products dispersed further from the summit area, resulting in a more hazardous event compared to the 8 November event that was largely confined to the upper part of the volcano.
