[1] The anisotropic characteristics of the Hikurangi subduction zone in central North Island, New Zealand are studied using shear-wave splitting measurements from 55 local earthquakes recorded on a 200 km profile of 19 stations. The eastern fore-arc shows trench-parallel fast directions and a low average delay time of 0.2 s. The source of anisotropy is confined to the upper 60 km and is likely to be deformation induced within the overriding Australian plate. Central western North Island shows N… CONTINUE READING
