This document discusses various types of natural disasters including earthquakes, cyclones, floods, droughts and tsunamis. It outlines disaster management strategies for each type of event. For earthquakes, it recommends preparing homes located in seismic zones and taking cover during shaking. For cyclones, it suggests developing emergency kits and evacuating to shelters when warnings are issued. Flood management involves both hard engineering like dams and soft techniques like afforestation. Droughts are addressed through rainwater harvesting, watershed management and irrigation. Tsunami preparedness requires early warning systems and coordination between response agencies. The overall goal of disaster management is to reduce damage through preparedness, mitigation and coordinated response.

8. PRE-MANAGEMENT
OF EARTHQUAKE:-
This management is
related to preparedness
factor. To safeguard your
house, check in which
seismic zone your house is
existing.
HAITI EARTHQUAKE

9. 2)POST MANAGEMENT OF EARTHQUAKE:-
In post
management, we
are considering the
precautions to be
taken during and
after the earthquake.
By using GIS & GPS
system impact of
earthquake can be
calculated.
EARTHQUAKE

10. DURING THE EARTHQUAKE
Take cover. Go under a
table or other sturdy
furniture; kneel, sit, or
stay close to the floor.
Hold on to furniture
legs for balance. Be
prepared to move if your
cover moves.
Ref.: Haiti earthquake,2010

11. IF OUTDOORS:-
Move into the open,
away from buildings,
street lights, and utility
wires. Once in the
open, stay there until
the shaking stops.

12. AFTER EARTHQUAKE:-
If the building you live in is in
a good shape after the
earthquake, stay inside and
listen for radio advises. If you
are not certain about the
damage to your building,
evacuate carefully. Do not
touch downed power line.

13. HAITI EARTHQUAKE
A massive 7.0-
magnitude earthquake has
struck the Caribbean nation of
Haiti on 12 JAN,2010.The
extent of the devastation is still
unclear but there are fears
thousands of people may have
died. Haiti's worst quake in two
centuries hit south of the
capital Port-au-Prince on
Tuesday, wrecking the
presidential palace, UN HQ
and other buildings.

14. CYCLONE
Cyclones caused due to
atmospheric disturbances
around a low-pressure
area distinguished by swift
and often destructive air
circulation. They are
usually accompanied by
violent storms and bad
weather. The air circulates
inward in an anticlockwise
direction in the northern
hemisphere and clockwise
in the southern
hemisphere.

17. CYCLONE FORECASTING SYSTEM
Monitoring process has
been revolutionized by the
advent of remote sensing
techniques. A TC intensity
analysis and forecast
scheme has been worked
out using satellite image
interpretation techniques
which facilitate forecasting
of storm surges. Satellite
based observations are
being extensively utilized

18. CYCLONE MANAGEMENT
Before cyclone season:-
Prepare an emergency kit
containing: A portable radio,
torch and spare batteries;
Stocks dry food – Chura,
Chhatua, Mudhi, gur, etc.
Matches, fuel lamp, portable
stove, cooking utensils,
waterproof bags
A first aid kit, manual, etc. Trim
dry tree branches, cut off the
dead trees and clear the
place/courtyard of all debris,
including coconuts and tree
branches.

19. UPON CYCLONE WARNING
Listen to your local radio / TV,
local community warning
system for further information. .
Take special care for children,
elders, sick, pregnant women
and lactating mothers in your
family. Do not forget your
emergency food stock, water
and other emergency items. Go
to nearest cyclone shelter.
Do not venture into the sea for
fishing.

20. ON LOCAL EVACUATION
Lock your home, switch off
power, gas, water, and take
your emergency kit. If
evacuating to a local shelter or
higher grounds carry the
emergency kit and minimum
essential materials. Wear strong
shoes or chappals and clothing
for protection.

21. ON CYCLONE
STRIKING :-
Disconnect all electrical
appliances and turn off gas.
If driving, stop – but well away
from the sea and clear of
trees, power lines and
watercourses. Stay in the
vehicle.
After the cyclone:-
Check for gas leaks. Do not
use electric appliances, if wet.
Listen to local radio for official
warnings and advice.

22. FLOOD
Floods are the most
frequent natural disaster
that India has to face
almost every year. Flooding
is caused by the
inadequate capacity within
the banks of rivers to
contain the high flows
brought down from the
upper catchment due to
heavy rainfall.

23. FLOOD FORECASTING
The Flood Forecasting
involves the following four main
activities:-
(1) Observation and collection of
hydrological and hydro-
meteorological data;
(2) Transmission of Data to
Forecasting Centers;
(3) Analysis of data and formulation
of forecast; and
(4) Dissemination of forecast.

25. MANAGEMENT OF FLOOD
Flood management
techniques can be divided
into two types,
1) Hard engineering option
2) soft engineering option.
MANAGEMENT OF FLOOD

26. HARD ENGINEERING OPTION
1)Dam construction
Dams are often built
along the course of a river in
order to control the amount
of discharge. Water is held
back by the dam and
released in a controlled way.
2) River engineering
The river channel may
be widened or deepened
allowing it to carry more
water
Flood in eastern region

27. SOFT ENGINEERING OPTION
1)Afforestation:
plant trees near the banks
of river.
2)Managed
flooding: The river is
allowed to flood naturally in
places, to prevent flooding
in other areas-for example,
near settlements.
3) Planning:
planning of societies
should be away from the
floodplain.
Afforestration

28. PRECAUTION FOR FLOOD
BEFORE THE FLOOD:-
Have an emergency kit on hand
which includes a: A portable
radio, torch and spare batteries;
Stocks of fresh water, dry food
(chura, mudi, gur, biscuits), etc.
FLOOD IN BIHAR

29. ON WARNING:-
Tune to your local
radio/TV for warnings and
advice. Keep dry food,
drinking water and clothes
ready
During floods:-
Drink boiled water.
Do not let children remain
on empty stomach.
Rescue action during flood

30. DROUGHT
Droughts in the
Indian region are mainly
due to various kinds of
failures of rains from
southwest monsoon.
Rainfall is the ultimate
source of water, affecting
production of crops and
other biomass by direct
falling on the fields as well
as supporting surface and
ground water irrigation.

32. DROUGHT MANAGEMENT
It can be done by three stages,
1)Rain water harvesting
2)Watershed management
3)Modern techniques of
irrigation.

33. TSUNAMI
Tsunamis can be
generated when the sea floor
abruptly deforms and
vertically displaces the
overlying water. When large
areas of the sea floor elevate
or subside, a tsunami can be
created.

35. TSUNAMI MANAGEMENT
It suggested setting up of a
National Disaster Management
Authority under the Union Home
Ministry which had set up an
emergency control room. It also
kept in constant touch and
coordinated with the three wings
— Army, Navy and Air Force –
were participating in relief and
rescue measures in a big way,
flying sorties and shipping tonnes
of relief material.

36. CONCLUSION
1) Disaster management decreases the
destruction ability of disaster.
2) Disaster management makes us able to face
the disasters.
3) Disaster management safeguard to human
beings.
4)The awareness about disaster management is
needed.
