Disaster

refers to a sudden calamitous event that brings great damage, loss, destruction and devastation to life and property.

Natural Disasters

It is caused by natural forces, such as earthquakes, typhoon, volcanic eruptions, hurricanes, fires, tornados, and extreme temperatures.

Man-Made Disasters

It is caused by man in which major direct causes are identifiable intentional or non-intentional human actions.

Disaster risk

the potential disaster losses in lives, health statuses, livelihoods, assets, and services which could occur in a particular community or a society over some specified future time period.

CLIMATE CHANGE

can increase disaster risk in a variety of ways – by altering the frequency and intensity of hazards events, affecting vulnerability to hazards, and changing exposure patterns.

ENVIRONMENTAL DEGRADATION

changes to the environment can influence the frequency and intensity of hazards, as well as our exposure and vulnerability to these hazards.

POVERTY AND INEQUALITY

Impoverished people are more likely to live in hazard exposed areas and are less able to invest in risk-reducing measures.

POORLY PLANNED AND MANAGED URBAN DEVELOPMENT

The growing rate of urbanization and the increase in population density (in cities) can lead to creation of risk, especially when urbanization is rapid, poorly planned and occurring in a context of widespread poverty.

WEAK GOVERNANCE

Unwilling to assume their roles and responsibilities in protecting rights, providing basic services and public services

Vulnerability

the susceptibility of an individual or a group of people on the impact of natural hazard.

Exposure

degree to which a community is likely to experiment hazard events of different magnitude

Social Vulnerability

inability of people, organizations and societies to withstand adverse impacts to hazards due to characteristics inherent in social interactions, institutions and systems of cultural values.

Physical Vulnerability

the element exposed to hazard during typhoon if the houses are destroyed 

Hazard

It is defined as the source of danger and something that may cause injury or harm. It is also the uncertain course of events in a country.

NATURAL HAZARD

a naturally occurring physical phenomena having atmospheric, geologic or hydrologic origin. Type of hazards that arises from natural processes in the environment.

QUASI-NATURAL HAZARD

type of hazard that arises through interaction of natural processes and human activities. Examples are SMOG, WATER POLLUTION AND AIR POLLUTION

TECHNOLOGICAL HAZARD

type of hazards arises directly as a result of human activities

EARTHQUAKE

A vibration on the surface of the Earth as a result of sudden release of energy due to the movement of plates

GROUND SHAKING

This describes the vibration of the ground where an earthquake occurs which is usually recorded in terms of intensity.

GROUND RUPTURE(cracks on the ground/fault)

primary hazard caused by an earthquake. Ground rupture happens on areas where the fault zone moves.

LIQUEFACTION

secondary effect of an earthquake described as collapse of buildings caused by earthquake vibrating water-saturated fill or unconsolidated soil.

Subsidence

is the lowering of the ground surface often occurs during an earthquake

Liquefaction

is the phenomena in which the strength and stiffness of the soil is reduced by earthquake shaking.

Earthquake-induced landslides

Landslides refer to a wide range ground movement such as rock fall and debris flow.

Earthquake-induced ground subsidence

potential earthquake hazards results the lowering of the ground surface often occurs during an earthquake.

FIRE

might happen when ground shaking results to breakage of gas, electrical lines and fuel lines, and overturning of stoves

TSUNAMI

It is the seismic sea wave in a water body caused by the displacement of a large volume of water generally in an ocean or a large lake.

In an earthquake map, moderate intensity is represented by?

Magma

molten rocks found beneath the Earth

Sulfur dioxide

is the toxic gas released naturally by volcanic activity

Silica content

characteristics of magma mainly affects the explosiveness of a volcanic eruption

Viscosity

property of substances to resist flow

Mudflow

is the emission of voluminous quantities of loose, unconsolidated tephra which become deposited on the landscape

Lava Flow

Is the most damaging to property, as they can destroy anything in their path

Gustatory

is the sense that is not used in detecting premonitory events before a volcanic eruption.

Harmonic tremors

is the signs of an impending volcanic eruption refers to the swelling of volcano that signals the accumulation of magma near its surface.

Chemical content, temperature and turbidity

are the following that should be continuously monitored to in a lake or hot spring around a volcano
