Landslides in blanket peat on subantarctic islands: causes, characteristics and global significance / Alan P. Dykes, Jennifer M. Selkirk-Bell.
Title: | Landslides in blanket peat on subantarctic islands: causes, characteristics and global significance / Alan P. Dykes, Jennifer M. Selkirk-Bell. |
Author(s): | Dykes, Alan P. Selkirk-Bell, Jennifer M. |
Date: | 2010. |
Publisher: | [Amsterdam]: Elsevier |
Abstract: | Analysis of peat slides on sub-Antarctic Macquarie Island and Marion Island indicates they are three times more frequent than in British Isles because combined effect of factors including constituent vegetation and rainfall pattern promotes formation of smooth, impermeable iron and organic pans at base of peat. Results suggest that failures in peat slopes result from peat accumulation reaching natural maximum thicknesses with respect to intrinsic stability thresholds. Different vegetation on different slopes influences shear strength of blanket peat on Macquarie Island, and in general, sub-Antarctic peat landslides are visually similar but quantitatively different from Irish examples. |
