Summary Studies of S to P conversion at the base of the crust of waves from a number of local deep earthquakes have indicated a crustal thickness of 24 km ± 3 km and 31 km ± 4 km beneath the New Zealand Seismograph Stations of Wellington (WEL) and Gisborne (GNZ) respectively. Considerable spread in the data indicates that results obtained from isolated earthquakes can be inconclusive, and that the concept of a Mohorovičić Discontinuity without small scale irregularities may well be inadequate.
