Abstract
The strong-motion records obtained during the Milford Sound earthquake of 4 May 1976 are of particular interest since the assigned intensities are exceptionally low for an earthquake of magnitude 7. The recorded ground motions are presented here in the general format proposed for publication of significant earthquakes recorded by the New Zealand strong-motion network. It is seen that the ground motions are consistent with the low intensities assigned.
Highlights
The Milford Sound earthquake was recorded by three-component accelerographs at Milford Hotel, Wanaki, and Te Anau, and by an acceleroscope at Haast
The peak acceleration components obtained by the strong-motion recorders are shown in Fig. 1 (a)
The largest acceleration is towards the general direction of the epicentre, as occurred in the case of the Milford Hotel accelerogram
