| Abstract: | Reversed Pn velocities have been determined from regional earthquake sources for the Wairarapa region in the southeast North Island, New Zealand. Values were 8.64 (±0.13) km/s in the easternmost part of the region and 8.90 (±0.13) km/s in the central Wairarapa, which are consistent with subducted Pacific plate lying at shallow depth under the region. A value of 8.22 km/s between Wellington and the Wairarapa region is interpreted as a possible difference in the velocity structure above the refractor between the two localities. |
