come in different forms and intensity.
Nobody knows when it will strike and how will it
happen. Therefore, everybody must know how to
determine possible disasters and anticipate possible
damages in order to prepare oneself from the potential
harms that it may cause to people and the community
Disaster
are phenomena that cause great physical
damage in a community infrastructure, its people and
their properties, e.g. houses and environmental sources
of living
Calamities
generally affect the physical
infrastructural facilities, agricultural productivity and
even lead to loss of life and cause damage to property.
Natural disaster
Victims of disasters may suffer from Post Traumatic
Stress Disorder (PTSD) and other serious mental health
conditions, which are not being given much attention
to by the authorities or even by the victims, themselves.
PSYCHOLOGICAL perspective
Filipinos are generally known as “matiisin”
, resourceful,
helpful, optimistic, and prayerful. These traits help a lot of
Filipinos to survive the challenge of COVID19 in the country.
To people who are used to natural calamities like typhoons,
flash floods, and volcanic eruptions most citizen would find
contentment with what they have at the moment.
Socio-cultural Perspective
Disasters affect the economic condition
of a community because they reduce local
and international trade. It can also
partially or totally paralyze a country’s
transportation system, just like what
happened in the COVID19 pandemic
ECONOMIC PERSPECTIVE
Natural disasters are commonly thought to be less
politically argumentative than armed conflicts, yet a
closer look shows that both the effects of a natural
disaster and the resulting distribution of humanitarian
aid are profoundly linked to politics.
Political PERSPECTIVE
Epidemic Level: Biological disaster affects large
numbers of people within a given community or area. Ex:
Dengue.
(b) Pandemic Level: Biological disaster affects a much large
region, sometime spanning entire continents or the globe
BIOLOGICAL PERSPECTIVE

Economic
People who trust political institutions will
find government risk assessments credible
and accept their hazard policies.
Low trust in public institutions means
citizens may ignore recommendations and
information provided by them.
Confidence in government aid during
disasters may reduce individual motivation
to take personal precautions
Political
loss of lives
public demobilization

Biological
openings, or vents where
lava, tephra (small rocks),
and steam erupt onto the
Earth’s surface.
volcano
When magma
reaches the surface, it’s
called
Lava
volcanic gases
Carbon dioxide,
Sulfur dioxide,
Hydrogen sulfide, and
Hydrogen halides
any surface changes on a volcano
(subsidence/sinking, tilting, bulging);
often use of tiltmeters as well as
satellite imaging which results to less
exposure on the ground or safer for
volcanologists.
GROUND DEFORMATION
when magma rises up, it breaks rock
along the way. Thus, earthquakes are
generated. Monitoring of
quakes/tremors is done by using a
seismometer that determines which
patterns of seismic waves precede an
eruption.
SEISMIC ACTIVITY
monitor types and rate of emission of
different gases; Concentrations of
gases are sometimes high enough to
create acid rain that kills vegetation
around the volcano
GASES
intensified presence of steam;
visual
rumbling sounds are heard
auditory
observed foul smell (usually rotten
egg caused by sulfur) caused by presence of
volcanic gases
olfactory
ground movement/earthquake is felt
tactile
