In the last decades, Mt. Stromboli produced four vulcanian eruptions, in 2003 and 2007 and July and August 2019, recorded by INGV monitoring network. Specifically, last three events are studied through records from borehole strainmeters, which allow to infer details on source dynamics. These events are preceded by a slow strain buildup, starting several minutes before the paroxysms, which can be used in future for early warning. Eruptions consist of two or more strain pulses, with oscillations ranging from several seconds, as in 2007, to some minutes, as in 2019, and lasting from several minutes to 1 hr after the explosions.

Abstract
In the last decades, Mt. Stromboli produced four vulcanian eruptions, in 2003 and 2007 and July and August 2019, recorded by INGV monitoring network. Specifically, last three events are studied through records from borehole strainmeters, which allow to infer details on source dynamics. These events are preceded by a slow strain buildup, starting several minutes before the paroxysms, which can be used in future for early warning. Eruptions consist of two or more strain pulses, with oscillations ranging from several seconds, as in 2007, to some minutes, as in 2019, and lasting from several minutes to 1 hr after the explosions.File in questo prodotto:
