Explosive vent sites on Mercury: Commonplace multiple eruptions and their implications

Explosive volcanic vents are widespread on Mercury. Compound comprise multiple individual vents, and probably formed through events. We demonstrate that ~70% of the vent sites Mercury have been imaged with sufficient resolution to resolve their internal features compound undergone eruptions. Interior characteristics such as cross-cutting relationships, contrasts in small scale impact cratering, other textural detail, well asymmetry surrounding faculae, suggest activity occurred over a prolonged but so far unquantified period time. use case studies highlight migration eruption centres at these sites. At Nathair Facula vent, small-scale interior pits location most recent activity.
