Examples are closing of business, damage of properties, death livestock, etc. Vulnerability - Characteristics and circumstances of a community, system or asset that makes it susceptible to the damaging effects of hazard. Vulnerability. Examples are houses built near rivers or above the mountains. Capacity - Strengths, attributes and resources available within a community, society or organization. Exposure - People, property, systems, or other elements present in hazard zones. Disaster Risk - The potential disaster losses in lives, health status, livelihoods, assets and services. General Classification of Hazards: 1\. Natural: A.Geophysical Example: -Earthquake - Among the deadliest of natural hazards. -Volcanic Eruption - Once Volcanic eruption occurred their will shaking of the ground and followed by tsunami. -Liquefaction - too much water example is Tsunami Mass Movement Dry -Rock fall -Subsidence -Mass movement B.Meteorological Typhoons or tropical cyclones or hurricanes are closed circulation systems in the atmosphere which combines low pressure and too strong winds. Hurricane, typhoon, and cyclone are all the same, it is only differ in name depends on the location of the country (northern, west, south, or east Pacific). C.Hydrological - example flooding D.Climatological Example: -Drought -Extreme temperatures: Heat wave -prolonged period of excessively hot and also humid weather relative to normal climate patterns. Cold wave/extreme cold - prolonged period of excessively cold weather. \- Wildfire - uncontrolled burning fire outdoors; caused by natural and human activities; aka bush fire, forest fire. \- Urban fire - occurring in metropolitan areas involving buildings with potential for spreading adjoining structures. \- El Nina and El nino E.Biological Example: -EPIDEMICS - Avian Flu, Ebola, Cholera, Malaria, Dengue, Measles, COVID 19, HIV/AIDS, Meningitis, Tuberculosis \- ANIMAL / INSECT INFESTATION ASF 2\. Technological/Manmade A.INDUSTRIAL ACCIDENTS \- Originating from technological or industrial accidents, dangerous procedures, infrastructure failures or certain human activities. EXPLOSIONS: Chemical, Nuclear B.TRANSPORT ACCIDENTS \- Used to describe technological transport accidents involving mechanized modes of transport: air, boat, rail, and motor vehicles. C. COMPLEX EMERGENCIES \- Result from several different hazards or more often to a complex combination of both natural and man-made causes and different causes of vulnerability. Characterized by extensive violence and loss of life, massive displacements of people, widespread damage to societies and economies resulting from internal or external conflict. D. FAMINE / FOOD INSECURITY HAZARDS \- Brought about by multiple root causes, such as severe drought, conflict, poverty, worsening debt crisis, or mismanagement or abuse of resources. -Where do we monitor weather? PAG-ASA or windy.com? Volcanic vent - volcanic mouth Lahar - not advisable to inhale Severe drought - cracking of the ground
