This pair of manuscripts (2025-6539 and 6540) constitute a significant step forward in the modelling of ballistic hazards from volcanic explosive activity at a volcano that has an unparalleled dataset (collated by these authors, building on previous work) and where there is considerable tourist activity particularly in the summer months (with hiking trails - for which this paper assesses the hazard - going to the active summit craters). There is therefore both considerable scientific interest in this paper (in the methods and moving the field forward) but also wider public interest.
