Webb1 jan. 2000 · Plinian eruptions are more stable, involving larger volumes and higher intensities (Cioni et al., 2000) and leading to massive fallout deposits. WebbPeak intensities (magma discharge rate) of 45 Pleistocene and Holocene plinian eruptions have been inferred from lithic dispersal patterns by using a theoretical model of pyroclast fallout from eruption columns. Values range over three orders of magnitude from 1.6 × 10 6 to 1.1 × 10 9 kg/s.
