Silicic calderas globally tend to record a cyclic magmatic, structural, and eruptive
evolutionary progression. Some calderas are polycyclic, involving multiple catastrophic …

On 17 September 1996 the Soufriere Hills Volcano started a 9 hour period of dome collapse
involving 11.7× 106 m³ (DRE) of lava. After 2.5 hours of quiescence a sustained explosive …

The thermal structure of a generic subduction zone is investigated to elucidate the source
region of subduction zone volcanics. The steady state thermal field is evaluated for a model …

When magma vents into the sea or a crater lake, the ensuing magma‐water interaction can
affect the style of eruption dramatically. If the mass of surface water incorporated into the …

The dichotomy between explosive volcanic eruptions, which produce pyroclasts, and
effusive eruptions, which produce lava, is defined by the presence or absence of …

More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Understanding the influence of bubble foams on magma permeability and strength is critical
to investigations of volcanic eruption mechanisms. Increasing foam porosity decreases …

The scope of this chapter is limited to the dynamics of lava and gas rising in a volcanic
conduit. No mention will be made of the behaviour of eruption columns in the atmosphere …

The pyroclastic deposits of many basaltic volcanic centres show abrupt transitions between
contrasting eruptive styles, eg, Hawaiian versus Strombolian, ordry'magmatic versuswet' …

Domes offer unique opportunities to measure or infer the characteristics of magmas that, at
domes and elsewhere, control explosive activity. A review of explosive activity associated …
