Abstract
The Hikurangi Subduction Zone represents one of New Zealand’s most significant seismic hazards. Consequently, understanding the driving factors which influence subduction zone behaviour such as the role of ‘rough’ subduction is of key focus. Along the Hikurangi Margin, numerous seamounts on the down-going Pacific Plate protrude several kilometres above the surrounding Hikurangi Plateau, resulting in significant deformation to the overlying Australian Plate as they are ‘swept under the rug’. This talk presents examples of seamounts at varying stages of subduction along the Hikurangi Margin and discusses the role such features may play in subduction zone behaviour.
