The Engineering Seismology section of the Physics and Engineering Laboratory, DSIR, has recently published the above volume presenting the results of computer analyses of twenty, three-component, accelerograms recorded by the New Zealand Strong-Motion Network. It contains a brief introduction, three tables summarising the accelerogram characteristics, site information and earthquake information, and the results of the computer analyses. The results presented for each accelerogram begin with a heading page, followed by computer plots of acceleration, velocity and displacement histories, acceleration response spectra and Fourier amplitude spectra. The spectral values are also tabulated.
