Geology of Stromboli

Geological Evolution of Stromboli (7)

Present Sciara volcano: Between 10'000 and 5'000 y B.P. the NW slope of Stromboli collapsed again. The landslide left behind a horseshoe shaped depression in the summit area and its deposits can be found in the sea NW of the island to a depth of 2000m. Pyroclastic material and lava flows then re-built this section of the volcano and they also cover the summit area of Pizzo. Recent ash deposits are also found in all terrain depressions on the S-, E- (Rina Grande) and NE side of Stromboli. However, these are not shown in the map (units 28-31).
