We report a detailed tephrostratigraphic characterization of the 5.7 m long NDT09 marine sediment sequence retrieved from the Marsili Basin in the southern Tyrrhenian Sea. Glass composition was determined through a combination of electron microprobe analysis (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), while textural analyses of tephra particles were conducted using scanning electron micr...

At Stromboli volcano (Italy) the regular, persistent activity is occasionally (2–4 events/year) interrupted by sudden, short-lived and more energetic major explosions, being intermediate in size between regular Strombolian activity and even more powerful paroxysmal explosions. Despite being frequent and hazardous, the magma source depth, the triggering mechanisms and timescales of such major explosions are still poorly underst...
