(Fig. 2.15) Strombolian Eruption.
When the magma is viscous, the locked up gas will escape intermittently when rising to the surface. Often this results in blocks and bombs which will fall on the surrounding environment. Lava flows as well as cinder cones may be produced by Strombolian eruptions. Stromboli volcano is situated in the Aeolian Islands, North of Sicily, Italy, Europe.
