• Lesson 1: Basic Concept of Disaster and Disaster Risk

  
• Disaster


  A sudden calamitous event, bringing great damage, loss, destruction and devastation
• Ring of fire


  A path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes
• Calamity


  An event causing great and often sudden damage or distress
• Volcanic eruption


  When lava and gas are discharged from a volcanic vent
• Earthquake


  Shaking of Earth caused by waves moving on and below the Earth's surface
• Typhoon


  Type of tropical cyclone, also known as severe tropical storm
• Natural disaster


  A natural event such as flood, earthquake or hurricanes that causes great damage or loss of life
• Man-made disaster


  Disasters caused by human in which major origin is intentional or non-intentional
• A disaster is a serious disruption of the functioning of a community or a society involving widespread human, material, economic or environmental losses and impacts, exceeding the ability of the community to cope using own resources. (UNISDR, 2009)
• A disaster risk is the probability of harmful consequences or expected losses resulting from interactions between natural or human- induced hazards and vulnerable conditions
• Hazard


  Phenomenon or situation, which has the potential to cause disruption or damage to people, their property, their services and their environment
• Vulnerability


  Is a condition determined by physical, economic, social and environmental factors or processes which increase the susceptibility of a community to the impact of hazards
• Capacity


  The opposite of vulnerability. It is the combination of a community's strengths, characteristics and resources that can be utilized to achieve certain goals
• Disaster risk


  Risk is the combination of probability of an event and its negative consequences. (UNISDR, 2009)
• Risk= Hazard x Exposure x Vulnerability / Capacity
• Types of disaster


  • Natural Disaster
  • Environmental Disaster
  • Human-induced Disaster
• Natural Disaster


  • Geophysical
  • Hydrological
  • Meteorological
  • Climatological
  • Biological
  • Extraterrestrial
• Risk factors


  • Severity of Exposure
  • Gender and Family
  • Age
• Effects of disaster
• Groups affected by disaster
• Environmental Disaster
• Human-induced Disaster


  • Technological (Industrial hazard, structural collapse, fire, air pollution, infrastructure disruption, cybersecurity, hazardous materials, food contamination)
  • Societal (Armed conflict, civil unrest, financial crisis, terrorism, chemical, biological, radiological, nuclear, and explosive weapons)
• Philippines is a high risk index location for disasters
• Disasters can affect human lives, residence, economy, infrastructure, and environment
