pyroclastic activity starts generating long-runout massflows. Edifice growth is ultimately limited to a critical point at which it fails. Past cones were probably similar to the current edifice, built primarily from voluminous unconsolidated pyroclastic deposits, making them susceptible to large-scale, deep-seated failures. Currently we appear to be near the end of the edifice growth phase. Understanding the cyclic nature of this record, including redefining the number of cycles will be critical for developing realistic probabilistic hazard models. Forecasting models can be refined by considering not just return periods of debris avalanches but also the preconditioning of the edifice to failure, and the type and nature of other hazards at different parts of the cycle.
