Thanks goes to Steven E. Ingebritsen for pointing out that in the original article there is a discrepancy between equation (2) and the depth versus hydraulic conductivity curve shown on Fig. 8. Inspection of the error showed that equation (2) is incorrectly presented and that the correct equation (2) should be:

$$ \log {\text{ }}k = - 1.38{\text{ }}\log {\text{ z}} - 15.4 $$

with permeability k in m/s and depth z in km.

The curve on Fig. 8 is displayed correctly in the paper and also the discussion refers to the correct curve and equation.
