Short summary
Pyroclastic deposits are the only records left by pyroclastic flows at Vesuvius, and deposits from past eruptions are the only way to get information about the expected range of impact parameters. It is necessary to investigate the deposits first and then define a general model of the current that links deposit characteristics to flow dynamics, finally reconstructing the impact parameters that better represent flow intensity in terms of damaging potential. This is the way the paper is organized.
