The document summarizes research on tephra aggregation from the February 2010 eruption of the Soufriere Hills volcano on Montserrat. Fine ash particles adhered together during transport in the eruption plume, forming aggregates that influenced ash dispersal. Field work analyzed aggregates in tephra deposits at different distances from the volcano. Results showed aggregates had similar grain size distributions and internal structures reflecting the conditions in the stratified eruption plume. Understanding aggregation provides insights to improve models of tephra dispersal and hazard assessments.
