Mass eruption rate, column height, and duration dataset for volcanic eruptions

This report describes a dataset assembled and curated as part of a project funded by the Earthquake Commission Biennial Grant 20781, Towards real-time probabilistic ash deposition forecasting for Aotearoa New Zealand. This dataset compiles measured, estimated, and calculated values for volcanic eruption mass eruption rates, column heights, and durations. Data comes from 213 eruptions, with about a third from New Zealand volcanoes. 65% of eruptions have a value for all three parameters. Eruptions are further classified according to magma and eruption type to prepare for further analysis. This dataset will be used to develop prior probability density functions (PDFs) for mass eruption rate (MER), column height, and duration to quantify uncertainty in volcanological inputs with the aim of production of real-time probabilistic ashfall forecasts.
