Violent explosions yield new insights into dynamics of Stromboli volcano



Crystal-poor magma may be a chief factor in the steadiness of activity at the Stromboli volcano in Italy. This was one of the findings to emerge from the documentation of a number of violent explosions there last year. The findings are giving scientists new insights into the dynamics of the volcano.

Stromboli, on an island of the same name in the Aeolian Archipelago, is known as “the lighthouse of the Mediterranean” because of its persistent explosive activity, which is visible from great distances. The well-documented explosions, however, were more violent than normal “strombolian” activity, and we call them “paroxysmal” explosions.
