Rayleigh wave dispersion has been observed along the three profiles
Trieste-Olbia, Olbia-Bologna and Olbia-Bolzano, in central-northern Italy.
The interpretation of phase velocities indicates a crustal thickness increasing
from East (25-30 km, Trieste-Olbia) to West (30-35 km, Olbia-Bolzano).
For each profile two values of the Moho depth are acceptable; the shallower
one is associated with a set of models which have low velocity
material (¡3=4.3 lcm/s) just under or within a few km from the Moho;
the deeper one still accepts low velocity material ((3=4.4 km/s) under
the Moho but does not exclude the presence of an almost normal LID
above the low velocity channel
