1. Disaster
management
submitted by : Sanchi
Class: X

2. Hazard is a dangerous event,
natural or human included that
could cause injury, loss of life or
damage op property, livelihood
or environment .
For e.g.. Rail, road and air
accidents, terrorist attack ect.

3. disaster
A disaster is weather natural or
human included, is an event
which results in widespread
human loss. it is accompanied by
loss of livelihood, property
causing suffering and loss in a
definite area.

4. Disaster management
1.Response and
relief
2.Rehabilitation
and
reconstruction
3.Mitigation
4.preparedness

6. Response and relief
Immediate measures taken during or
after the disaster to ensure the effects
are minimized.

7. Rehabilitation and
reconstruction
The operations taken after disaster to help the
affected people by giving them money and
reconstructing the damages.

8. mitigation
It Is any action taken to minimize
the extent of a disaster or
potential disaster.
It includes improving plantation,
relocation of villagers into safer
areas, practicing and promoting
disaster resistant construction
techniques.

9. preparedness
Activities
and measures
taken before
a hazard
event to
ensure
effective
response to
the impact of
hazards.

10. floods
Floods are temporary
inundation of large regions as
a result of an increase in
reservoir , rivers, flooding of
their banks because of heavy
rains , tsunami, wind storms or
dam burst.

13. tsunami

14. Mitigation strategies for
floods

15. Buildings on elevated areas

16. Land use control

17. Flood zone mapping

18. cyclones
Cyclones are violent storms, often
of vast extent, characterized by
high winds rotating about a calm
center of low atmospheric
pressure. This is center moves
onward. Often with a velocity of 50
km an hour !

21. Mitigation strategies for
cyclones

22. Multipurpose cyclones shelters

23. 2. Protection
against wind.
3. Construction
on roads which
are elevated.
4. Hazard
mapping.
5. Land use
control.

24. earthquakes
An earthquake is a
sudden release of
energy accumulated in
deformed rocks
causing the ground to
tremble or shake.
Earthquake is a
sudden onset disaster

27. A
seismograph
is an
instrument
which is used
for measuring
earthquakes

28. Mitigation
strategies for
earthquakes

29. 1.Engineered structures should be
designed and built to withstand ground
shaking.
2.Before the building is constructed, the
balding plan should be checked by the
municipality or by any architecture.
3.Public awareness programmers should
be made.

30. landslides
Landslides are masses of rock,
earth or derbies which move by
force of their own weight down
mountain slopes of river banks
.they occur without any warning.

33. Mitigation strategies
for landslides.

34. 1.Drainage correction : maintenance of
natural drainage channels.
2.Engineered structures with strong
foundations can withstand the
ground movement forces.
3.Increasing vegetation cover.
4.Hazard mapping

35. 5. Retaining wall

36. droughts
A drought is a climatic
anomaly, characterized by
deficient supply of
moisture resulting either
from sub-normal rainfall,
erratic rainfall
distribution, higher water
need or a combination of
all the factors.

39. Mitigation strategies
for droughts

40. 1.drought monitoring and early
warning.
2.Drought awareness programme.
3.Land use planning.
4.Crop insuring – this is an insurance
given to the farmers, who have lost
their crops because of lack of water
supply.

41. 5. Rain water harvesting
