Description:
The individuation of areas that are more likely to be affected by new
events in volcanic regions is of fundamental relevance for the mitigation
of the possible consequences, both in terms of loss of human life and
material properties. Here, we describe a methodology for defining flexible
high-detail lava-hazard maps and a technique for the validation of the
results obtained. The methodology relies on: (i) an accurate analysis of
the past behavior of the volcano; (ii) a new version of the SCIARA model
for lava-flow simulation (based on the macroscopic cellular automata
paradigm); and (iii) high-performance parallel computing for increasing
computational efficiency. The new release of the SCIARA model
introduces a Bingham-like rheology as part of the minimization algorithm
of the differences for the determination of outflows from a generic cell,
and an improved approach to lava cooling. The method is here applied to
Mount Etna, the most active volcano in Europe, and applications to landuse
planning and hazard mitigation are presented.
