Types and Classification
In the following table shows a schematic landslide classification adopting the classification of Varnes 1978 and taking into account the modifications made by Cruden and Varnes, in 1996. Some integration have been made by using the definitions of Hutchinson (1988) and Hungr et al. 2001.

| Bedrock | Engineering soils | ||||
| Predominantly fine | Predominantly coarse | ||||
| Falls | Rockfall | Earth fall | Debris fall | ||
| Topples | Rock topple | Earth topple | Debris topple | ||
| Slides | Rotational | Rock slump | Earth slump | Debris slump | |
| Translational | Few units | Rock block slide | Earth block slide | Debris block slide | |
| Many units | Rock slide | Earth slide | Debris slide | ||
| Lateral spreads | Rock spread | Earth spread | Debris spread | ||
| Flows | Rock flow | Earth flow | Debris flow | ||

Famous quotes containing the word types:
“The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.”
—Henry Brooks Adams (1838–1918)
