Presents the anisotropic structure of the Hikurangi subduction zone in New Zealand. Assessment of the shear-wave anisotropy of surface-wave polarizations; Elaboration of symmetry axis of the anisotropic structure; Anisotropic characteristics in the subducted crust underlying the mantle.

Investigates Rayleigh-wave dispersion to determine the shear-wave velocity structure in North Island, New Zealand. Implication of surface-wave study for the thickness of the upper-mantle; Use of anisotropy to explain the presence of high velocities; Indication of the result of the mantle velocities from the isotropic inversions of the S-wave velocity.

Alex Brisbourne reports on a one-day discussion meeting organized by SEIS-UK for seismologists to discuss current seismological research undertaken in the UK and to consider how the provision of new seismic equipment and training facility may enhance that work. [ABSTRACT FROM AUTHOR]
