2. 1. Introduction
• Disasters can fall into one of three types
• Natural-Caused by a natural event
• Environmental-Related to environmental problems
• Incited-Provoked and urged on
• Disasters are often classified by cause
{Alexander, 2000; Burton et al., 1993; Cutter, 2001}:
• Natural (e.g., floods, droughts, landslides, volcanoes,
hurricanes, earthquakes, winter storms, tsunami),
• Technological (e.g., chemical spills or releases,
computer failures, train derailments, plane crashes,
power outages, bridge collapses), or
• social (e.g., riots, willful acts such as arson or

terrorism).
3. 1. Introduction
• A disaster is a result from the combination of
hazard, vulnerability and insufficient capacity or
measures to reduce the potential chances of
risk. A disaster happens when a hazard impacts
on the vulnerable population and causes
damage, casualties and disruption [1]
• Any hazard – flood, earthquake or cyclone which
is a triggering event along with greater
vulnerability (inadequate access to resources,
sick and old people, lack of awareness etc)
would lead to disaster causing greater loss to life
and property.

5. 1. Introduction
• Hazard may be defined as “a dangerous condition or event, that threats or
have the potential for causing injury to life or damage to property or the
environment.”
– Natural and Manmade.
• Vulnerability may be defined as “The extent to which a community,
structure, services or geographic area is likely to be damaged or disrupted
by the impact of particular hazard, on account of their nature, construction
and proximity to hazardous terrains or a disaster prone area.”
• Risk is a “measure of the expected losses due to a hazard event occurring
in a given area over a specific time period. Risk is a function of the
probability of particular hazardous event and the losses it would cause.”
The level of risk depends upon:
• Nature of the hazard
• Vulnerability of the elements which are affected
• Economic value of those elements
• Capacity can be defined as “resources, means and strengths which exist in
households and communities and which enable them to cope with,
withstand, prepare for, prevent, mitigate or quickly recover from a disaster”.

8. 1. Introduction
Disaster Strengths
• Over the past decade, the number of natural and
manmade disasters are continuously increasing
• From 1994 to 1998, reported disasters average was 428
per year but from
• 1999 to 2003, this figure went up to an average of 707
disaster events per year [1] showing an increase of
about 60 per cent over the previous years.
• The biggest rise was in countries of low human
development, which suffered an increase of 142 per
cent.
• In Pakistan 256,037 people were killed and 8,989,631
affected in the period from 1993 to 2007 (World
Disasters Report 2007).

9. 1. Introduction
Cost Impact
• Globally, the costs averaged $138 billion per year from 1988 to 1992
and $940 billion per year from 2000 to 2007 (International Federation
of Red Cross and Red Crescent Societies,2007).
• Globally the average of lives lost is approximately 228,597
(International Federation of Red Cross and Red Crescent Societies,
2007).
• The fundamental problems are that population is increasing, more
people are moving to urban high-risk areas, and our infrastructure is
increasing in complexity and value.
• The number of people affected by disaster damage worldwide is
typically one thousand times greater than the number of people killed
by disasters (Burton, Kates and White, 1996).
• Improved warnings and mitigation measures have reduced
significantly the number of lives lost in the technologically advanced
nations (UN Global Program, 2005).
