Highlights  Vesicles and volatile contents were measured in Mono Craters obsidian pyroclasts  Vesicle textures argue for formation of obsidian pyroclasts through ash sintering  Obsidians made of domains that underwent different degassing and shear histories  Obsidian pyroclasts formed by cycles of fragmentation, sintering, and relaxation  No evidence found for obsidian pyroclasts formation by pumice (foam) collapse *Highlights (for review) ABSTRACT 21 The ranges in intensity and style of volcanic eruptions, from highly explosive Plinian 22
