Stewart, D.L. 1996 Landslides triggered by the 17-19 March 1994 rainstorm, Dunedin area . Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 95/42 16 p.
Abstract: This report documents the location and nature of landsliding that occurred in response to the 17-19 March 1994 rainstorm in the Dunedin area, in southern New Zealand. Landslide locations are presented on a 1:50 000 scale map with available data pertaining to the landslides included in a database presented as tables within the report. This information has been compiled to indicate the extent of landsliding that occurred and is intended to aid future land-use planning. A large number of landslides occurred within the Dunedin area in response to the March 1994 rainstorm, of which 186 are documented in this report. Considerable damage to property and services resulted from the landslide activity. The majority of these landslides were debris flows and occurred in surficial materials on slopes of greater than 20 degrees. With two exceptions, the landslides were less than 2 - 3 m deep. A significant proportion (55%) of the landslides are thought to be first time landslides. (auth)
