摘要:

The Ponui Landslide (September 1976), in Southern Hawke's Bay, is a wedge failure in an Upper Miocene weak-rock alternating sandstone-mudstone and amalgamated sandstone succession. The planimetric area involved with failure covers 25 ha and represents the reactivation and enlargement of a previous landslide. The Ponui Landslide has a calculated volume of approximately 2.5 × 106m3.
