LESSON’S OBJECTIVES:Identify human activities that speed up or trigger landslides.

Suggest ways to help lessen the occurrence of landslides in your community.

HUMAN ACTIONS

THAT SPEED UP

LANDSLIDES

MINING•The use of explosives underground are like mini-earthquakes. This can cause a landslide. Also historic mining leaves gaps of 6-8ft. A shift in soil can cause a ground level drop of the same measurement, leading to a landslide

A landslide in Pantukan, the island of Mindanao, has swept away the homes of a gold mining village, killing at least 25 people and leaving more than 150 missing.

QUARRYING•It is an excavation or pit, usually open to the air, from which building stone, slate, or the like, is obtained by cutting, blasting, etc.

LAND POLLUTION•Land pollution is the degradation of earth's land surfaces often caused by human activities and its misuse. Haphazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few of the contributing factors.

Polluted land causing the landslide

EXCAVATION•In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavationsite or "dig" is a site being studied.

LAND USEExamples are construction of roads, houses etc.

Severe land use in Baguio City

LEARNERS’ TASK•Five groups will be formed.•Each group will create a ONE-MINUTE JINGLE that will showcase some ways on how to lessen landslides.
