What could be done to prevent mudslides or landslides?

Landslides or slips in urban areas, almost always have a source of water as their cause. Broken water or sewage mains are often to blame.

They occur where the ground has been inadequately consolidated, as in a subdivision of land; or where the land is steeper than its natural rest angle.

Rainfall in storm conditions will often saturate the soil structure, exacerbating the problem.
