Macroscale heterogeneities, including fissuring, development of fragipan cemented horizons and stratification, indicates that, as well as the general behaviour presented in this paper, there may also be significant local variation.In addition, the effects of soil microstructure, including bonding and particle shape and orientation, on overall soil behaviour are recognised, but have yet to be investigated in detail.
The builders were preparing the ground for construction of a school when they made the discovery, the tabloid newspaper reported.

In the wetter parts of the region, on Banks Peninsula in particular, periodic wetting leads to a variety of slope failures related to internal erosion (tunnel gullying) and rapid loss of shear strength (debris flows, soil slides and rotational failure).
Elsewhere in the drier parts of South Canterbury loess deposits commonly form vertical exposures and evidence of slope instability is comparatively rare.
The criticism should be levied at people who do that," Dave Bromwich, the president of the Chinese Friendship Society, said.
