An understanding of the mechanisms that lead to initiation of volcanic eruptive episodes, or to rapid changes in eruptive style once eruptions are underway, is critical for assessing and managing risks to human populations and infrastructure associated with volcanic activity. We seek contributions that constrain the nature and timescales of physical, chemical, dynamic and other processes that result in triggering of eruptions or rapid changes in eruptive style through application of geophysical, geodetic, geochemical, petrological and tephrostratigraphic methods, laboratory experiments, or numerical modeling. These might include theoretical studies of volcanic settings, study of modern eruptions where direct observational records are available, and constraints from ancient eruptions, where indirect evidence must be used to constrain initiation processes.
