Abstract
Three parameters, magnitude, intensity, and violence, can be used to characterise pyroclastic flow eruptions. Violence reflects the vigour with which a pyroclastic flow is emplaced. It is described quantitatively by the height of hills climbed by the flow (yielding flow-velocity estimates), the overall morphology of the deposit and by the proportion of the flow which forms an ignimbrite veneer deposit. Using the Taupo ignimbrite (New Zealand) as an example of an extremely violent flow, we relate violence to the eruption intensity. We consider that eruption magnitude and intensity control the gross distribution of a pyroclastic flow deposit.
