physical injury
Ø risk for emotional and physical health
problems
Ø Loss of life, home, property and
community.
Ø Material and Economics loss.
Ø Psychological Trauma.
Ø Displacement, Poverty, Exploitation,
Epidemics

accidents/Ship wrecks

Man-made Disasters
Ø Riots
Ø War
Ø Accidents (road, rail,
plane Crashes and ship wrecks)
Ø Deforestation
ØOver exploitation of natural
resources
Ø Construction Collapses –
houses, buildings, bridges
Ø Mine Tragedies
Ø Wildfires
Disaster Possibilities in India
Ø Peculiar Geographical
location
Ø Long coastlines –
surrounded by sea on three sides
Ø Snow- clad Peaks -
Himalayas
Ø High Mountain Ranges
Ø Perennial Rivers
Ø High Population
Ø Over exploitation of
Natural Resources
Ø Northern Region falls under
the Seismic Zones III to V (Prone to landslides, floods, droughts, and
earthquakes)
Ø Eastern Zone is prone to
heavy floods (Perennial Rivers like Brahmaputra and Ganges)
Ø North- Eastern Zone comes
under seismic zone IV and V (Chance for floods, landslides and earthquakes)
Ø Western region is known for
severe drought, wind erosion of land and soil and earthquakes
Ø Southern coastal region is
vulnerable to cyclones, sea erosion, tsunami, and landslides
Ø Human greed and mismanagement
Ø Mass felling of trees
Ø Soil and sand mining
Ø Construction of huge dams
and drying up of rivers
Impact of Disasters
Ø Damage to life and property
Ø Wide spread destruction of
life and nature
Ø Disrupt communication
system, power supply, water supply and drainage
Ø Health care and hospitals
are affected
Ø Commercial and economics
activities are disrupted
Ø Severe psychological
traumas
Ø Famine
Ø Rehabilitation Problems
Ø Riots affects the poorest
sections of the society
Disasters in India

Ø Gujarat earthquakes: 2001
Ø Mumbai- Gujarat floods:
2005
Ø Indian Ocean Tsunami: 2004
(280000)
Ø Uttarakhand Flashfloods:
2013
Ø Hurricane
Phailin Orissa & AP : 2013
Ø Patna – Kanpoor Train
Tragedy: 2016
Ø India Heatwave: in 1998 and
2015 (2500 each)
Prevention:
Ø It is
impossible to prevent natural calamities; however, it is possible to minimize
the impact of natural calamities such as floods, earthquakes, wild fires,
droughts, landslides and famine
Ø Preparing a master plan for
construction of infrastructure
Ø Ensuring quality materials
for construction
Ø Enforcing laws for safety
and security in construction
Ø Technically assessing
existing buildings
Ø Ensuring a regular
monitoring mechanism
Ø Controlling constructions
in Ecologically fragile areas
Ø Proper coordinating of
different departments
Ø Ensuring roles of NGOS
Ø Timely rehabilitation
should be ensured
Ø Should have trained rescue
team with well equipped technologies
Ø Preparing good evacuation
plans
Ø the organization and
management of resources
Ø Preparedness, response
and recovery in order to lessen the impact of disasters.
Ø Timely relief works
Ø Permanent disaster
management system
Ø Early warning system
Ø Most
natural calamities cannot be predicted, and using some form of early warning
system is the best way to deal with them
Ø The
effects of drought and famine can be mitigated by better management of water
resources. Rain water harvesting techniques are useful.
Ø Building
sturdier houses in non-seismic activity zones is a recommended way to deal with
earthquakes.
Ø Using
modern technology to warn people of an impending natural calamity, such as a
tsunami or flood, is an effective way to reduce casualties and damage
Ø Dams
change the nutrient content in waters downstream and alter water temperatures,
which in turn affects the growth of populations.
Ø They
sometimes necessitate costly repairs and maintenance, and dam breaks create
safety hazards.
Ø Water conservation is one of the most
obvious precautions to take during a drought.
Ø Droughts are typically accompanied by
extreme heat, so precautions should be taken around the home to stay cool.
