Seismic Site Effects in Owhiro Bay Quarry, Wellington: Field Observations and Numerical Modelling
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Local topography and geology are well known factors affecting the intensity of seismic shaking. We have investigated the seismic site effects at a site of the Owhiro Bay Quarry in Wellington, New Zealand, using instrumental records and numerical models.

Shallow Shear‐Wave Reflection Surveys in the Wellington Central Business District
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Seismic reflection profiling using shear waves provides constraints on the thickness of sediments beneath the Wellington Central Business District. Standard seismic methods were modified for urban environments where limited grassed areas are available and levels of cultural noise are high.

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.This study focuses on the subsurface structure of the Wellington basin and an assessment of the shaking potential due to the basin edge‐effect at its western margin. Seismic reflection surveys combined with gravity modelling provide data for a structural model from which to base our shaking analysis.

SPAC: An alternative method to estimate earthquake site effects in Mexico City [PDF]
Geofísica Internacional, 2003 Microtremor recordings are a very useful tool for microzonation studies because of simple data acquisition and analysis. The Spatial Autocorrelation Method (SPAC) proposed by Aki (1957), may be used to constrain the velocity structure underlying the site
