TOWARDS DEFINING STROMBOLIAN ACTIVITY DURING THE 20TH CENTURY

Strombolian activity is the typical eruptive phenomenology of the Stromboli volcano, on the homonymous island in the Aeolian Islands archipelago (Sicily, Italy). Defined as moderate explosive activity (but also capable of violent events), it was included within a classification of eruptive activity by Mercalli at the beginning of the 20th century. Over the course of the century, the definition would be broadened by scientists such as Lacroix, Ponte, Rittmann, Gèze and many others, until arriving at the current terminology, the result of research and constant monitoring by technologically advanced institutes, that keep a close watch on the volcano.
