Torlable Curve

When probability and consequences of a scenario are evaluated, the total risk is equal (p*C) to the surface of the rectangle (sum of orange and blue areas). The blue area is the tolerable part of that scenario, the orange part is the intolerable portion. NB: the log-log scale requires some attention when interpreting the relative size of surfaces, as shown in the bar diagram at the right, in decimal scale.
