Bijan Yavar is a research fellow, PhD student, and founder and CEO of MEPCO. The document discusses definitions of risk, emergency, crisis, and disaster from perspectives of both certainty and uncertainty. It provides details on definitions of disaster risk and crisis from various sources. Crisis is defined as a point of change that can have both negative and positive outcomes, while disaster refers to events beyond a community's capacity to respond on its own.

3. There are many terms which need more attention such as: Uncertainty,
Ignorance, Ignoring the Ignorance, Reliability, Flexibility, perception,
vulnerability, risk (soft, Semi Soft and Hard), DRM Theories (Chaos, SCCT, Black
Swan Effect, etc), etc.
We would hereby explain in brief the Definitions of Risk, Emergency, Crisis and
Disaster to prepare a platform for a better understanding, to better decide and act.
Disaster
Can you Notice , Identify and recognize The Difference Between a Disaster
(Natural Caused) and Crisis (Human Caused)?
Crisis
To better Understand What is an Incident is of high importance to better plan
and to implement the exact precautionary actions and also to plan for the
preparedness Phase and of course the response phase .
Emergency

4. Disaster Risk
The potential disaster losses, in lives, health
status, livelihoods, assets and services, which could occur to a
particular community or a society over some specified future time
period.
The definition of disaster risk reflects the concept of disasters as the
outcome of continuously present conditions of risk. Disaster risk
comprises different types of potential losses which are often
difficult to quantify. Nevertheless, with knowledge of the prevailing
hazards and the patterns of population and socio-economic
development, disaster risks can be assessed and mapped, in broad
terms at least.
Risk =
Hazard × Vulnerability
Capacity
Disaster
Risk
Risk is the probability of occurrence and to better say the
probability of occurrence of an Incident, Crisis, Disaster or
whatsoever it may be.

6. The oxford English dictionary defines an emergency as:
“a serious, unexpected , and potentially dangerous
situation requiring immediate action.” in the field of
crisis management , emergencies are events that need
a professional response from people who are specially
trained and equipped to cope with them.
Most emergencies are relatively minor events that can
be dealt with in a routine way using resources that are
normally available.
It is evident that not all emergencies are disasters, but
all disasters are emergencies, as the latter is much
broader and less restrictive term. (Encyclopedia of
Crisis Management, 2013)
Emergencies can occur either as a result of cumulative
processes or as materialization of a sudden threat. (Ibid)

7. Crisis
As we may know the topic has a
multidisciplinary theme. For this the author
has suggested to focus on the definition of
crisis.
There have been many definitions for crisis
especially by the new kind and set of crisis
generated in today’s changing world from
different aspects, viewpoints and different
factors internally and externally causing it.
Based on the literature reviewed the
definition for crisis shows to be problematic
and there are some debates on the crisis
exact definition (Smith, 2005).
Victor L. Heller and his colleague John R.
Darling (2012) by referring to (Shelton et al.,
2003) have mentioned that crisis definition is
related to different variables. Which is means
a world of variable verities and
diversification.

8. Crisis
Heller and his colleague (2012) has a definition for crisis
where it states that: A “crisis” can be determined as senses of
fear, panic and peril or danger, and the proportionate intraorganizational impacts that these senses and feelings may
have.
As stated by Lee (1999) crisis is how and the way to see,
which can be a changing and turning point that can be named
Sight. From the other hand based on (Darling, et al., 2002)
and in the same path, Heller and his colleague (2012) propose
that: a Crisis is a time of criticalness and a point for change
and turn which can prepare a wrong or better status. The
crisis is a condition where it has approached to the crucial
stage. crisis has also been defined as a point of change or
turn, either in the mindset or whatsoever it may be causing
and generating positive and better or negative and worse
conditions (Heller, et al., 2012) they also add that a crisis
although having large negative effects, even though Big names
such as Toyota car manufacturing company as an example can
also have positive effects in the firms future life only when it
will take its chance and opportunity to make good and correct
operations rearrangements (and changes) to help constancy
of positive development and growth.

9. Crisis
From a view, crisis is a complex of situations that produces
task demand to an organization that is out of the range of
an organization’s capability to adapt without the use of the
extra significant or frequently external sources (Smith,
2005).
Based on another definition mention by (Zhong, 2009) in
line with (Parsons ., 1996) crisis is a probability of low
occurrence, great impact phenomenon that endangers the
livability (and continuity) of organizations and is determined
by uncertainty of reason, impact, and means of intent,
besides by a faith that as soon as possible the decisions
should be made.
Crisis is something unexpected and quick by their origin
which the majority mainly concentrates on the effects and
how to mitigate instead of the causes which generated it
(Kippenberger, 1999).
It is important to point out that the crisis shows up to
twinkle in the most safe assumptions of all cooperations.
(Nurmi and darling, 1997 as cited in Heller, et al., 2012)
which is been specified as “Black Swan”
Crisis in another definition is a horror which cannot be
easily seen and is invisible and awaiting us (Parsons, 1996).

Disaster
Disaster Is referred to a critical disorder in a community functioning or vast
material, economic, environmental and human (indirect) disorders, effects and
destructions involving the community which is beyond the capability to
respond and to cope self-sufficiently (UNISDR, 2009).
Sometimes Crisis and Disaster are used interchangeably which may cause a
misunderstanding and ambiguity. To make it clear, at first the causes of the
occurrence of an incident should be analyzed in depth and after the analysis it
will help to better understand and distinguish whether the incident occurred
has changed into a crisis or a disaster which by this means will help to make
better decisions and to act much more accurately.
