Constructing reliable hazard assessments for volcanoes is critical to mitigate the impact of future activity on communities and infrastructure. Such hazard assessments require detailed information on the styles, timing, and magnitude of previous eruptions and distribution of their products. The dispersal of deposits and tempo of eruptions can be established by combining information from both proximal and distal records (including marine, lacustrine and ice cores), and from field and laboratory data. We encourage contributions that use volcanic deposits to obtain information on eruptions, especially those that map deposit distributions, derive the characteristics of individual eruptions from such deposits, and delineate reliably dated eruption histories. Multidisciplinary contributions combining field-based methods with archival research, new techniques, or methods from other scientific disciplines are encouraged, as are ideas on integrating such studies with hazard and risk management strategies.
