The geological interpretation is based on representative horizontal slices at decreasing altitudes. The slice at 950?m (Fig. 5a) displays a central roughly circular high-density feature corresponding to the inner part of Gran Cono (Fig. 1) and is delimited by the 1906 crater. We attribute the high-density values to the feeder conduit and to dense (low porosity) lava layers emitted at the beginning of the 20th century (1906–191534; Fig. 119 in ref. 35) that overlap in correspondence to the buried rim.
