Anthropogenic Flashcards
How does anthropogenic factor in the occurrence of mass movement
Anthropogenic factors include deforestation which is the removal of trees which indirectly contribute to mass movement e.g. landslides,mudslides. Three stabiliser soil way through switch help prevent soil erosion by binding soil together and absorbing excess water. Without vegetation source be more vulnerable to erosion as rain water directly reach the ground, causing particles to be dislodged or carried away by surface run-off. This may lead to quillies. Deforestation can change soil composition, and the amount of water the soil can hold. Deforestation that occurred 5 to 7 years preceding the landslide event have significant influence on the occurrence of mass movement. And example is the OSO landslide which involved of the collapsing of saturated hillside comprise of clay salt and sand, resulting in massive degrees floor which killed many people and destroyed infrastructures. This also left side is linked to deforestation has OSO has a history of logging.
