Smith, W.D.; Maunder, R.D. 1980 Microseismic noise survey in Lower Hutt. [s.l.]: [s.n.]. Report / Geophysics Division 142 15 p.

Abstract: As part of a joint DSIR programme to evaluate relative seismic risk throughout the Hutt Valley, a survey of microseismic noise has been carried out. Measurements were made in two frequency bands and spectra calculated at a selection of sites. The overall pattern is one of the seismic noise level decreasing northwards away from the Petone foreshore, and of low levels also on the hills on either side of the valley. (auth)
