The document defines a hazard as a dangerous phenomenon, substance, activity, or condition that can cause harm, damage, or loss. Hazards can be classified into natural, quasi-natural (interactions between natural phenomena and human activities), and man-made. Natural hazards include geological events like earthquakes and tsunamis, hydrometeorological events like floods and droughts, and biological events like disease outbreaks. Impacts of hazards include physical damage and injuries, psychological trauma, social and economic disruption, and environmental effects.

Basic Concept of Hazard
Terminology: Hazard Presentation title 20XX 2 United Nations Office for Disaster Risk Reduction (UNDRR), formerly known as the United Nations International Strategy for Disaster Reduction (UNISDR), define hazard as a dangerous phenomenon, substance, human activity or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihood and services, social and economic disruption, or environmental damage. What is the difference between a hazard and a disaster? A hazard has only the potential to cause destruction or negative impacts to life and property, whereas a disaster is a hazard that already occurred and already caused destruction and devastating impacts. In other words, a disaster is a hazard that affected a vulnerable population or assets.
Classification of Hazards Presentation title 20XX 3
Hazards can be classified into three main categories: Natural, Quasi-natural, and Man- made Hazards. Presentation title 20XX 4
1. Natural Hazards are naturally occurring phenomena or processes. Presentation title 20XX 5
2. Quasi-natural Hazards are hazards that are outcomes of the interaction of natural phenomena and man- made activities. Presentation title 20XX 6
Man- made/Human- induced/Anthropo genic Hazards are those that result from human activities and actions. Presentation title 20XX 7
OTHER CLASSIFICATION OF HAZARD Presentation title 20XX 8
1. Natural, 2. Technological 3. Environmental Degradation. Presentation title 20XX 9
Natural Hazards are naturally occurring phenomena or processes. Natural hazards can be classified into three categories: Presentation title 20XX 10
Geologic Hazards are natural phenomena or processes that occur in the Earths Crust. Examples: earthquakes, tsunami, volcanic eruptions, mass movement such as landslides and rockslides, subsidence, liquefaction. Presentation title 20XX 11
Presentation title 20XX 12
B. Hydrometeorological Hazards are atmospheric, hydrological, and oceanographic natural processes or phenomena. Examples: - tropical cyclones: tropical depression, storms, typhoons, and super typhoons 8 - hurricane - floods and flash floods - tornado - hailstorm - thunderstorms - drought - blizzards Presentation title 20XX 13
Presentation title 20XX 14
Biological Hazards living things or substances from living things that can cause illnesses and diseases or any harm. Examples: - outbreaks of epidemic diseases in humans, animals, and plants - infestations Presentation title 20XX 15
Presentation title 20XX 16
Technological Hazards are man-made hazards caused by technological, infrastructure, or industrial accidents or failures. Examples: nuclear explosion, industrial pollution, vehicular accidents, industrial explosions and fires, and collapse of buildings. Presentation title 20XX 17
Presentation title 20XX 18
Environmental Degradation are processes caused or induced by human activities or in combination with natural hazards. Examples: - deforestation, land degradation, loss of biodiversity - land, water, and air pollution - climate change - ozone depletion Presentation title 20XX 19
Presentation title 20XX 20
Types of Hazards 1. Slow onset hazards are hazards that have early signs or indicators before its occurrence. Slow onset events include: * sea level rise; * increasing temperatures; * ocean acidification; * glacial retreat and related impacts; * salinization; * land and forest degradation; * loss of biodiversity; * desertification. Presentation title 20XX 21
Types of Hazards 2. Rapid or sudden onset hazards are hazards that occur or strike without any prior signs or warnings. *Tropical cyclones, typhoons, hurricanes, tornadoes, blizzards; hydrological hazards including coastal floods, mudflows; or geophysical hazards including earthquakes, tsunamis, volcanic eruptions Presentation title 20XX 22
Impact of Hazards 1.Physical Impact death and injuries (casualties) of people, and destruction or damages to properties and infrastructures. 2.Psychological Impact psychological trauma, chronic anxiety, depression, and other emotional and mental disorders. Presentation title 20XX 23
Impact of Hazards 3. Socio-cultural Impact migration, alteration of traditional social status, loss of cultural identity, ethnic conflicts, sexual abuse and domestic violence, and changes in lifestyle. 4. Economic Impact loss of employment, livelihood and property/land. Presentation title 20XX 24
Impact of Hazards 5. Environmental Impact environmental contamination, loss of forests and natural rivers. 6. Biological Impact spread of epidemic diseases to people, flora and fauna. Presentation title 20XX 25
Hazards Signs and Symbols These signs and symbols with corresponding meaning below help people to be extra cautious, aware and observant in surroundings. Each picture is designed to become recognizable to anyone as a signal word like danger or warning. Presentation title 20XX 26
Technology or Man Made Hazards Signs and Symbols FLAME - Flammable - Self-heating - Emits Flammable Gas - Pyrophoric Presentation title 20XX 27
HEALTH HAZARD - Reproductive toxicity - Respiratory sensitizer - Target organ toxicity - Aspiration toxicity Presentation title 20XX 28
EXPLODING BOMB - Explosives - Self-reactives - Organic Peroxides Presentation title 20XX 29
SKULL AND CROSSBONES - Fatal or toxic - Acute toxicity Presentation title 20XX 30
Natural Hazards Signs and Symbols Presentation title 20XX 31
Quasi-Natural Signs and Symbols ENVIRONMENT - Aquatic toxicity - Air toxicity Presentation title 20XX 32
