  DEFINING DISASTERS DEFINING DISASTERS Theterm "disaster" originated from the French word "desastre" which is a combination of the words "des" meaning bad and "aster" meaning star. From this, it can be inferred that disaster literally means bad star. Disaster happens when communities lack the capacity to adapt to disruptions that further affect the socio-economic, political, psychological, and cultural stateof individuals and families in communities. However, the impact of disasters varies depending on geographical location and vulnerability of population, among others.

  DISASTER RISK DISASTER RISK Accordingto United Nations International Strategy on Disaster Reduction (ISDR), disaster risk is the potential loss in lives, health status, livelihoods, and various assets which are often challenging to quantify. Disaster risks can be categorized as INTENSIVE or EXTENSIVE. Intensive risks involves the exposure of large number of people in a specific geographic area to extreme events that can further lead to catastrophic disaster impacts involving high mortality rate and asset loss. Extensive risks is concerned more on the exposure of dispersed populations to various hazards of low or moderate intensity.

  DISASTERS AND HUMAN DISASTERSAND HUMAN POPULATIONS POPULATIONS In the past decade , the Philippines, along with China, US, India, and Indonesia were among the top five countries that are most frequently hit by natural disasters. Natural disasters remain as one of the major causes of death. They account to 9655 people killed with an annual average of 107,000 and 124.5 million victims worldwide with annual average of 268 million from 2002 to 2011.

  HUMAN-INDUCED HUMAN-INDUCED HAZARDS HAZARDS This kind ofhazard sprouts from technological or industrial conditions which includes infrastructure failures or specific human activities. Like transport accidents and chemical spills. Because of our highly interconnected world, the transportation of hazardous products products becomes easily available to several communities. If the population does not have adequate policies to regulate the use of hazardous materials, this may pose serious health risks to them.

  NATURAL HAZARDS NATURAL HAZARDS Natureoperates dynamically, making it very unpredictable. Natural hazards are phenomena that may cause severe death toll, damage to property, environment, and socio-economic condition of communities. There are different types of natural hazards depending on their precursor, namely;

  Directly linked toan organic origin caused by exposure of living organisms to toxic substances and microorganisms that cause sickness. Examples includes epidemic diseases caused by viral and bacterial infection. BIOLOGICAL HAZARD BIOLOGICAL HAZARD GEOLOGIC HAZARD GEOLOGIC HAZARD Events that originated in solid ground count as major precursor. These includes earthquakes, volcanic eruptions and emissions, and other secondary hazards such as landslides and mudflows. HYDROMETEOROLOGICAL HAZARD HYDROMETEOROLOGICAL HAZARD This hazards includes typhoons, thunderstorms, tornadoes, floods, and even drought, among others. This involves phenomena that are of atmospheric, hydrological or oceanographic nature that may cause loss of life.
• 9.
  EXPOSURE EXPOSURE Exposure is anotherconcept in disaster risk. This refers to people and properties that are affected by hazards. Exposure can be measured by the number of people or types of assets in the area. Geographical location is a crucial factor. Those who live below the mountains areas are more exposed to hazards such as landslides and rock falls than those who are in the cityscapes.
• 10.
  SENSITIVITY SENSITIVITY This is thedegree to which a certain community can be affected by hazards. For instance, a community dependent on rain-fed agriculture is more sensitive to rainfall pattern changes than a community where mining is the primary source of income.
• 11.
  ADAPTIVE ADAPTIVE CAPACITY CAPACITY Adaptive capacity asthe ability of an individual or a community to withstand and adapt to continuous environmental changes. Moreover, the adaptive capacity of an individual and communities depend on their access to and control over wide- ranging resources.
• 12.
  VULNERABILITY VULNERABILITY The concept ofvulnerability explains how people and the differences among them contribute to the situation or context wherein they operate. Vulnerability comes in many types, namely; social, psychological, and physical vulnerability.

  SOCIAL IMPACTS SOCIAL IMPACTS Theprimary damage of disasters could be the destruction of buildings and infrastructures. The impact of disasters are intertwined with the social aspect of communities, including housing, health, education, transportation, and political instability.
• 15.
  The destruction ofhouses which may be brought by floods and earthquakes can lead to homelessness. This can further have a long-term impact in the society. HOUSING HOUSING HEALTH HEALTH Health care infrastructures in most parts of the developing world are vulnerable to hazards because of poor facilities. When hospital equipments are damaged, hospitals cannot accommodate people affected by calamities. EDUCATION EDUCATION In the Philippines, school facilities often serve as evacuation and relief centers when a disaster strikes. One of the greatest impacts of disasters to education is the disruption of educational services that can have long-term effects to both students and teachers.
• 16.
  ECONOMIC ECONOMIC IMPACTS IMPACTS Several experts saythat basic structures of the economy is a major determining factor on the degree of vulnerability to hazards. This notion suggests that each sector of the society has a part and too much focus on a single aspect may lead to undesirable outcomes.
• 17.
  ENVIRONMENTAL ENVIRONMENTAL IMPACTS IMPACTS Disasters create substantialenvironmental degradation and ecological imbalance which lessens the quality of people's lives. Trees can be uprooted due to typhoons, hurricanes, and strong winds, and there could be forest fires when lightning hits a dry land. Natural disasters are by definition degrading to society.
