Lesson 1: Basic Concept of Disaster and Disaster Risk Flashcards
Natural or man-made emergencies that cannot be
handled by affected communities who experience
severe danger and incur loss of lives and properties
causing disruption in its social structure and
prevention of the fulfillment of all or some of the
affected community’s essential functions.
DISASTERS
Any phenomenon that has the potential to cause
disruption or damage to humans and their
environment. An event or occurrence that has the
potential for causing injury to life, property and
environment.
hazard
The probability of harmful consequences, or
expected loss of lives, people injured, livelihoods,
disruption of economic activities and damages to the
environment as a result of interactions between natural
or human induced hazards and vulnerable/capable
conditions.
risk
Is the situation of people, infrastructure, housing,
production capacities and other tangible human assets
located in hazard-prone areas.
EXPOSURE
Comprises conditions determined by physical,
social, economic, and environmental factors or
processes, which increase the susceptibility of a
community, school, or certain area in a locality to the
impact of hazards.
VULNERABILITY
Are those positive resources and abilities which are
helpful to individuals, families and community in
mitigating, preparing for, responding to and
recovering from the hazard impact.
CAPACITIES
This formula suggests that the risk of a
disaster is influenced by the interaction of the
hazard, the exposure of elements at risk, and
their vulnerability, while also considering the
capacity of the system to deal with and recover
from the impact.
Disaster Risk = Hazard x Exposure x Vulnerability
Capacity
are natural phenomena. Natural factors
include geological events (earthquakes, volcanic
eruptions), meteorological events (storms, floods), and
biological factors (epidemics). The best way to manage
hazard impacts is to be aware of how it occurs and its
accompanying consequences, mitigate against, and plan for
actions to be taken before, during and after a phenomenon.
Natural Disasters
A feeble shaking to
violent trembling of the
ground produced by the
sudden displacement of
rocks or rock materials below
the earth’s surface.
EARTHQUAKES
Hurricanes, typhoons,
and cyclones can bring
strong winds, heavy rainfall,
and storm surges, causing
flooding and wind damage.
STORMS
The inundation of land
areas which are not normally
covered by water. A_____ is
usually caused by a
temporary rise of the water
level of a river, stream or
other water course.
FLOOD
is a
process wherein volcanic
materials such as molten or
hot fragmented rocks or
gaseous materials are ejected
from a volcano.
VOLCANIC ERUPTIONS
Giant sea waves
generated by under-the-sea
earthquakes and volcanic
eruptions.
TSUNAMI
is a prolonged dry period in
the natural climate cycle that
can occur anywhere in the
world.
is a slow-onset of disaster
characterized by lack of
precipitation, resulting in a
water shortage.
DROUGHT
The outbreak of
infectious diseases can
lead to widespread
illness and strain
healthcare systems.
EPIDEMICS
