Abstract
hazmap-2.4 is a computer program for simulating sedimentation of volcanic particles from discrete point
sources and to obtain the corresponding ground deposit (deposit mode). Moreover, hazmap-2.4 is able
to evaluate the probability of overcoming a given loading threshold in the ground deposit by using a set
of different wind profiles recorded in different days (probability mode). For example, when the point
sources are specified along a vertical line located above the volcano crater, the code is able to simulate
the dispersion from a Plinian column, subject to a given wind profile, and to obtain the mass distribution
and settling velocity spectrum in the deposit.
