2. LOOK AT SOME OF THESE PICTURES OF
RECENT DISASTERS

7. Origin from the French word
“Desastre”
‘des’ meaning bad and
‘aster’ meaning star
DISASTER =>‘ Bad or Evil
star’.
A disaster can be defined as an occurrence
causing widespread destruction and distress.
Disaster

8. A disaster is a result
from the combination
of hazard,
vulnerability and
insufficient capacity
or measures to reduce
the potential chances
of risk.

9. Any phenomenon that has the
potential to cause disruption or
damage to people and their
environment
A hazard is a natural event while the disaster
is its consequence.
A hazard is perceived natural event which
threatens both life and property A disaster is a
realization of this hazard.”
-John Whittow

10. The extent to which a community,
structure, service or geographic area is
likely to be damaged or disrupted by the
impact of particular disaster hazard
E.g.
• People
• Property
• Essential services
• Environment
• economy

11. Natural disaster are hazards
which are caused because of
natural phenomena

12. Types of Natural Disasters
Drought
Volcanic eruption
Tornadoes/
Hurricanes/ Typhoons
Tsunamis
Floods
Earthquakes

13. Caused by the release of built up pressure caused by the shifting
of tectonic plates
It occurs at the area where tectonic plates meet
Magnitude of earthquake is measured using Richter scale
Recorded by a device called seismograph

14. It is a temporary overflow of water onto land that is normally dry
Caused by the heavy rainfall and overflowing water bodies

15. An extreme shortage of rainfall or water in a
particular area
It is directly affects the crops and results in the
shortage of food for animals and humans

16. A Volcanic eruption occurs when hot material (lava) from the
earth’s interior (magma chamber) are thrown out of a volcano.
Lava, steam, broken rocks pieces , dust and gaseous
sulphur compounds are some of these “ejecta”

18. Tsunami
• It is a series of water waves
• It is caused by the displacement of a large volume of a water body.
• Caused by the underwater earthquakes, volcanic eruptions and
underwater explosions.
• Can destroy coastal areas.

19. Huge revolving storms caused by wind blowing around a central area of
low atmospheric pressure
Wind blows anti-clockwise in the northern hemisphere
and clockwise in the southern hemisphere

20. Typhoon – termed used when it formed
in the pacific ocean
Hurricane – termed used when it formed in the
Atlantic ocean
Cyclone - termed used when it formed in the
southern ocean and Indian ocean

21. A change in the stability of a slope
can be caused by a number of
factors, acting together or alone
• Groundwater pressure
• Loss of Soil fertility
• Soil erosion,
• Heavy rain, glaciers, melting ice
• Volcanic eruption

22. The disaster which are caused as a result of human
activities

26. Phases of DM:
• Preparedness
• Response
• Recovery
• mitigation
It refers to how we can protect or preserve
maximum of lives and property during a
disaster.

27. Preparedness Response Recovery Mitigation
Activities prior to
a disaster
e.g.
Preparedness
plans,
Emergency
exercises,
Training,
Warning systems
Activities during
a disaster
e.g.
Public warning
systems,
Emergency
operations,
Search and
rescue
Activities
following a
disaster
e.g.
Temporary
housing,
Claims processing
and grants,
Long term
medical care and
counseling
Activities that
reduce the
effects of
disasters
e.g.
Building codes
and zoning,
Vulnerability
analysis,
Public education

28. Principles of Disaster Management
• It is the responsibility of all spheres of government
• It should use resources that exist for a day to day purposes
• Individuals are responsible for their own safety
• Its planning should focus on large scale events
• It should recognize the difference between incidents and disasters
• It must take account of the type of physical environment and the
structure of the population
• It must recognize the involvement and potential role of non
government agencies

29. Importance of Disaster Management
• To avert a disaster
• To undertake the rescue operations
• To provide relief measures
• To undertake the rehabilitation programs
• To reduce trauma and tension
• To control death rate
• To protect the environment
• To minimize the loss

30. Role of Educational Institution in DM
• Act as a safe shelter
• Health Centre for the locality
• Disaster management information center should keep database of
population, health, institution.
• A Centre for learning and counseling
• The school can be a feeding Centre
• Training for DRM volunteers, village council members, teachers,
government officials and even students and parents.

31. Role of a Teacher in training DM:
• Generate Awareness of hazards and preparedness measures
• Prepare contingency plan for school in case of a fire and disaster
• Teacher should be told about primary escape route in school
• Train the children on first aid and rescue operation
• Initiate the process of plantation in the school and giving knowledge
on the types of trees to be grown.
• Generate awareness on water and sanitation among the children
• The teacher should be demonstrated the action to be taken when
trapped in a fire or any hazard.

32. “We, as teachers as responsible citizens of our
country should be a part and parcel of the
disaster preparedness drive taken up in”
