This study looks at the characteristics of seven translational peat slides on subantarctic Macquarie Island which have occurred since 1980. They have occurred in herb vegetation on a range of slopes between 5 and 35 degrees. Slides range in area between 375 and 1200 square metres. The associations between peat slides, seismic activity and intense rainfall events are discussed. Considerations of the long term stability of vegetated slopes on the islands leads to the conclusion that the failure of these slopes is inevitable.&rft.creator=PICKARD, JOHN &rft.creator=SELKIRK-BELL, JENNY M. &rft.date=2000&rft.coverage=northlimit=-54.5; southlimit=-54.7; westlimit=158.7; eastLimit=158.9; projection=WGS84&rft.coverage=northlimit=-54.5; southlimit=-54.7; westlimit=158.7; eastLimit=158.9; projection=WGS84&rft_rights=This data set conforms to the CCBY Attribution License (http://creativecommons.org/licenses/by/4.0/).
