FIGURE 9.52
Debris avalanches at km 36 along the roadway shown in
Figure 9.51.
There were no slope failures at the
beginning of construction in 1995. The photo, taken by the author, shows conditions during 2002, after several
years of El Nino. At this time construction was not complete.
FIGURE 9.53
Scar of debris avalanche of February 18, 1967, which destroyed two apartment buildings and took 132 lives in
the Larenjeiras section of Rio de Janeiro. The buttressed wall was constructed afterward. Debris avalanches
need not be large to be destructive.
