A natural disaster is the effect of earths natural hazards, for example flood, tornado, hurricane, volcanic eruption, earthquake, heatwave, or landslide. They can lead to financial, environmental or human losses. The resulting loss depends on the vulnerability of the affected population to resist the hazard, also called their resilience. If these disasters continue it would be a great danger for the earth
2. A natural disaster is the effect of earths natural
hazards, for
example flood, tornado, hurricane, volcanic
eruption, earthquake, heatwave, or landslide.
They can lead to financial, environmental or
human losses. The resulting loss depends on
the vulnerability of the affected population to
resist the hazard, also called their resilience. If
these disasters continue it would be a great
danger for the earth.
5. An earthquake is a shaking
of the ground caused by the
sudden dislocation of
material within the earth's
outer layer, or crust. When
forces pushing on a mass of
rock overcome friction
holding the rock in place and
blocks of rock slip against
each other a earthquake may
occur.
6. A flood is an overflow
of an expanse of water
that submerges land
Most common is when
rivers or streams
overflow their banks.
Excessive rain, a
ruptured dam or levee,
rapid ice melting in the
mountains
7. A Volcano is a vent in the
earth through which hot
gases and molten rock rise
to the surface. A cone
shaped mountain of
erupted material around
such a vent is also called a
volcano.Volcanic eruption
deadly,damaging property
and infrastructure.
8. "Tsunami" is the Japanese
word meaning tidal wave. A
tidal wave is a large sea wave
caused by a submarine
earthquake or volcanic
explosion. When the ocean
floor is tilted or offset during an
earthquake, a set of waves is
created. These waves are
similar to the concentric waves
generated by an object
9. Drought is a period or condition
of unusually dry weather within
a geographic area where
rainfall is normally present.
During a drought there is a
lack of precipitation. Droughts
occur in all climatic zones.
However, its characteristics
vary significantly from one
region to another.Drought usually results in a
water shortage that seriously
interferes with human activity
10. Hurricanes are seasonal storms
and are most prevalent in August
and September. They develop
fromeasterly waves, which can
laterdevelop into a tropical
depression with winds up to 31
miles per hour. Later,
it might develop into a tropical
storm with winds up to 73 miles
per hour
Hurricanes are huge tropical
cyclones that originate over oceans
near the equator, such as the
Caribbean Sea
12. FLOODS IN RIO DE JANERIO,BRAZIL
Ninth place is for the floods that occurred in Brazil. Heavy rains in Brazil caused
flooding and on 11th January massive mudslides and floods in the Mountainous
Region of the state of Rio de Janeiro rendered 23000 homeless.

24. Scale of Disaster
Is Dependent on :
• Lead Time Available.
• Intensity of Hazard.
• Duration.
• Spatial Extent.
• Density of Population & Assets.
• Time of Occurrence.
• Vulnerabilities existing in the
Elements at Risk.
•Hazard X Vulnerability =
Disaster
25. ELEMENTS AT RISK
• People
• Livestock
• Rural Housing Stock
• Houses Vulnerable
• Crops, Trees,Telephone, Electric
poles
• Boats, Looms, Working Implements
• Personal Property
• Electricity, Water and Food Supplies
• Infrastructure Support
26. AIMS OF DISASTER MANAGEMENT
•Reduce (Avoid, if possible) the
potential losses from hazards.
•Assure prompt and appropriate
assistance to victims when
necessary.
•Achieve rapid and durable
recovery.

29. Role Players in Disasters
• People : Individuals, House -Holds,
Volunteers
• Gram Panchayat : Sarpanch, Panchayati
Secretary, Panchayati Members
• Village Elders : Caste/Community/Religious
Leaders, Teachers, Doctors, Engineers,
Retired Army & Police Personnel
• Govt. Deptl. Officers : Agriculture, Medical,
Engineers (Housing, Roads & Buildings,
Irrigation) Revenue Department, Public
Health, Police etc. NGOs
30. DEFINITIONS OF “VULNERABILITY”
• “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…”
• “Vulnerability is the propensity of
things to be damaged by a hazard”.
31. DISASTER PREPAREDNESS
• Disaster preparedness aims at
minimizing the adverse effects of a hazard -
• Through effective precautionary actions
• Ensure timely, appropriate and efficient
organisation and delivery of emergency
response following the impact of a disaster.
32. PREPAREDNESS
• Vulnerability Analysis and Mapping to include
Resources.
• Assess strengthening requirements and execute.
• Funding for preparedness must be arranged.
• Peoples’ cooperation through Political leaders,
elders, Volunteers and NGOs
• Create lead time by interpreting Warnings
• Plan to include movement of resources with time
frame.
• Aim to reduce the destructive potential of
cyclones, timely & appropriate relief to victims
and quick & durable recovery
34. Disaster Response Activities
• Warning
• Evacuation/Mitigation
• Search and Rescue
• Assessment
• Emergency Relief
• Logistics and Supply
• Communication and information Management
• Survivor Response and coping
• Security
• EOC & coordination
• Expedite rehabilitation and reconstruction.
35. Role of individuals in prevention of pollution
1) Use low-phosphate, phosphate-free or biodegradable dishwashing
liquid, laundry detergent, and shampoo.
2) Don't use water fresheners in toilets.
3) Use manure or compost instead of commercial inorganic fertilizers to
fertilize gardens and yard plant.
4) Use biological methods or integrated pest management to control
garden, yard, and household pests.
5) Don't pour pesticides, paints, solvents, oils, or other products
containing harmful chemicals down drain or on the ground. Contact the
authorities responsible for their disposal.
36. 6) Recycle old motor oil and antifreeze at an auto service center that has an oil
recycling program.
7) If you get water from a private well or suspect that municipal water is
contaminated, have tested by an EPA certified laboratory for lead, nitrates,
trihalomethanes, radon, volatile, organic compounds and pesticides.
8)Run water from taps for several minutes every morning before using the water for
drinking or cooking. Save it and use it to water plants.
If you have a septic tank, monitor it yearly and have it cleaned out every three to five
years by a reputable contractor so that it won’t contribute to groundwater pollution.
Do not use a septic tank cleaner, which contain toxic chemicals that can kill bacteria
important to sewage decomposition and that can contaminate groundwater if
systems malfunction.
9) Support ecological land-use planning in your community.
10) Get to know your local water bodies and form watchdog groups to help monitor,
protect, and restore them.
Editor's Notes
If you look at the right half of the slide you will find that the damage potential in the hazard causes the damages to the society
Life comes to a halt and the poorer sections of the society can never recover to the pre-disaster causes serious disruption to life of the society
But with awareness and preparation through action plans the society suffers less damages and is thus a more stable society.to recover faster.
