Similar pre-eruptive conditions behind contrasting explosive and effusive trachytic eruptions at Montagnone (Ischia volcano, Italy)

Abstract Most volcanoes on Earth display a range of eruptive styles, varying between effusive and explosive activity. Understanding the factors controlling these transitions is critical for volcanic hazard assessment but remains debated. While both pre-eruptive storage conditions...

Contrasting eruptive dynamics and hazards of two Holocene andesitic sub-Plinian to Plinian eruptions, Lower and Upper Citlaltépetl, at Pico de Orizaba, Mexico

Abstract Pico de Orizaba (Citlaltépetl) stratovolcano, eastern Mexico, preserves a complex Holocene explosive record, yet the eruptive dynamics, source parameters, styles, and hazard implications of individual eruptive episodes remain poorly constrained. Here, we examine the 9600...
