The information in Tables 2 and 3 on p. 421 was incorrectly submitted and leads to incorrect conclusions in the section on the stability analysis of Mount Indefatigable. Corrected versions of the tables are as follows:

TABLE 2. Sidescarp section, Mount Indefatigable: results of analysis using Sarma method

Rupture surface Earthquake Factor

Pore pressure Friction angle load, horizontal of safety

TABLE 3. Hypothetical section, Mount Indefatigable: results of analysis using Sarma method

Rupture surface Earthquake Factor

Pore pressure Friction angle load, horizontal of safety

0 40" 0.04 g 1.3 0 40" 0.04 g 1.6 0 30" 0.04 g 1 .O 0 30" 0.04 g 1.3 0 25" 0.04 g 0.9 0 25" 0.04 g 1.1

NOTE: g = acceleration of gravity; x = water table as indicated in NOTE: g = acceleration of gravity; x = water table as indicated in Fig. 15; rupture surface cohesion = 0 for all cases; interslice cohesion = Fig. 16; rupture surface cohesion = 0 for all cases; interslice cohesion = 100 kPa for all cases; interslice friction angle = 30" for all cases; unit 100 kPa for all cases; interslice friction angle = 30" for all cases; unit weight = 20 kN/m3. weight = 20 kNlm3.
