PREPARATION OF
RISK MAPS
Introduction
This document addresses the risk maps that
resulted from the experience carried out in the
emergency preparedness project in Peru. The
methodology will have to be revised according to
other more comprehensive risk reduction
experiences and strategies that are being
implemented institutionally but that lack
instruments such as the one described here.

Risk may be calculated, based on three elements:
a) the frequency and severity of a threat, b) the
vulnerability, and c) capacity of people,
communities and institutions to respond to such a threat and recover from its impact.
Therefore, the greater the risk, the greater the vulnerability of a community and the lower its
response and recovery capacity.
Risk map
The purpose of a risk map is to identify and classify areas, taking into account the probable
damages that could occur as a result of a disaster.
What is a threat?
A threat is defined as the probability that a potentially
destructive or damaging phenomenon or event may
occur (earthquakes, “huaycos,” floods, landslides,
tsunamis, droughts, wars, epidemics), and impact on
determined vulnerability conditions.
What is vulnerability?
Vulnerability is defined as the characteristics of
individuals, groups, or societies that determine its degree
of exposition to a threat or risk. Key characteristics
include class, ethnicity, gender, disability, age, and
condition.

member of the community
The groups that are especially vulnerable are those for whom it is difficult to survive and to
rebuild housing following a disaster.
