Natural disasters are
catastrophic events with
and hydrological origins
hurricanes, landslides) that
can cause fatalities,
property damage and social
sudden, rapid shaking of the
• the breaking and shifting of
• rapid movement of the
earth’s crust or outer layer
Droughts and Famines
• Famines are extreme shortages of food that cause people to die of
• Droughts are unusually long periods of insufficient rainfall
• Heavy rainfall within a short
duration of time in a particular
region which causes the rivers
and streams to overflow
• Tsunamis are massive sea waves that
are mainly caused due to earthquakes
in the ocean floor or possibly due to
an undersea landslide or volcanic
• When the ocean floor is tilted or
offset during an earthquake a set of
waves is created similar to the
concentric waves generated by an
object dropped into the water.
Hurricanes & Cyclone
• Hurricanes are massive storm systems that
form over warm ocean waters and move
toward land. Potential threats from
hurricanes include powerful winds, heavy
rainfall, storm surges, coastal and inland
flooding, rip currents, tornadoes, and
• Cyclone is an area of low atmospheric
pressure surrounded by a wind system
blowing in anti-clockwise direction, formed in
the northern hemisphere
Avalanche & Landslides
• type of landslide involving a large mass of
snow, ice and rock debris that slides and fall
rapidly down a mountainside
• masses of rock, earth or debris move down
a slope. Debris and mud flows are rivers of
rock, earth, and other debris saturated with
• caused by a variety of factors including
earthquakes, storms, volcanic eruptions, fire
and by human modification of land.
• A volcanic eruption occurs
when molten rock, ash
and steam pour through a
vent in the earth's crust.
• Man-made disasters can include hazardous material spills, fires,
groundwater contamination, transportation accidents, structure
failures, mining accidents, explosions and acts of terrorism. There are
actions that we can take to prepare to react appropriately to these
Hazardous Material Incidents
• Hazardous materials are chemicals that if accidentally released can
cause damage to the environment and health.
• Terrorism is designed to disrupt our lives and to scare us into making
changes in our national goals.
• No one is immune from terrorism.
• Biological attacks involve the release of germs or other biological
substance that results in illness.
Prevention, control and mitigation
1. Proper training of personnel working in the hazardous industries.
2. Proper maintenance and care of safety measures.
3. Removing human encroachments around hazardous industries.
4. Making the people aware about the first-aid methods in case of
5. Applying wet cloth over the mouth and nose in case of gas leakages
minimizes the health hazards.
6. Remaining indoors in case of radioactive accidents.
7. Providing the people with proper medical care, in some cases throughout
8. Providing adequate compensation to the affected people by way of
money and employment.
Disasters rescue forces
• National Disaster
Response Force (NDRF)
is a specialised force
constituted "for the
purpose of specialist
response to a
situation or disaster"
under the Disaster
Management Act, 2005
