Key Points The model of Johnson et al. (2016) does not realistically represent rock avalanche material composition Rock avalanche deposits contain large numbers of grains down to sub‐micron scale created by dynamic fragmentation during emplacement Fragmentation causes acoustic fluidisation of intensity and frequency several orders higher than predicted by the Johnson et al. model
