Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Mountain‐top spherules: Criteria to identify natural and synthetic particles
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 898-913, May 2026.Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.
