Landslides

1. LESSON’S OBJECTIVES:
Identify human activities that speed
up or trigger landslides.
Suggest ways to help lessen the
occurrence of landslides in your
community.

2. HUMAN ACTIONS
THAT SPEED UP
LANDSLIDES

3. 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

4. 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.

5. 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.

6. Landslide in La Libertad, Negros
Oriental caused by quarrying

7. 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.

8. Polluted land causing the landslide

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

10. Excavation causing landslide in China

11. LAND USE
Examples are construction of
roads, houses etc.

12. Severe land use in Baguio City

13. 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.
