On the landslide taxonomy above, the British Geological Survey writes:

The main classification criteria are: type of movement (falls, topples, slides spreads, flows), and type of material involved in the movement (rock, debris, earth). Combining movement and material type terms enables an appropriately descriptive landslide name to be formulated. Naming can become more detailed with the addition of other descriptive details related to activity state, water content , rate of movement, etc., if known (e.g. active, complex, extremely rapid, dry rock fall-debris flow).

Only a small selection of the wide spectrum of landslide types that may develop in nature are shown here.

Surely the image needs to be accompanied by an illustrative taxonomy of mitigative measures against landslides showing a wide spectrum of programs and strategies for inhabiting the geological wilderness.
