Abstract
    The ocean floor east of South Island, New Zealand, is a sub-continental region of predominantly east-west trend dominated by the Chatham Rise on the north and the Bounty Trough, which lies between the rise and the Campbell Plateau to the south. At least three banks exist on the rise. A system of submarine channels arises at the head of the Bounty Trough mainly as submarine canyons in the continental shelf and slope of south-east South Island. These channels coalesce to form a single channel that runs the length of the trough. At least three moderate-sized submarine canyons occur off the west coast of South Island. A geanticline trending north constricts the trough and is marked by the Mernoo Bank on the rise. The distribution pattern of earthquake epicentres shows northerly and easterly trends superimposed on the regional north-easterly structural trend of New Zealand for the north and north-west part of the area where information is available.
