drr review notes

• Climate Change is a risk factor characterized by long-term shifts in temperatures and weather patterns, altering the frequency and intensity of hazard events, affecting vulnerability to hazards, and changing exposure patterns
• Poorly-planned and Managed Urban Development risk factor of disaster does NOT include:

  • The adequate population in a certain area
• To prove that a disaster is natural, it must be:

  • A major event caused by Earth’s natural processes that result in significant environmental harm and loss of life
• Disaster is the culmination of risks that cause global negative consequences on the lives of assets of vulnerable and exposed people, resulting in injuries, deaths, and property damage
• A tsunami causing disruption in livelihood, loss of properties, and loss of public infrastructures affects the Sociocultural Perspective
• To consider the psychological perspective of residents after a disaster in a Disaster Risk Reduction (DRR) plan, the action should be:

  • Conduct Psychological First-Aid to affected residents
• Risks are the probability of harmful consequences or expected loss of lives, people injured, livelihoods, disruption of economic activities, and damages to the environment as a result of interactions between natural or human-induced hazards and vulnerable/capable conditions
• Examples of situations that show Economic vulnerability include:

  • Families with low incomes often live in high-risk areas around cities
• The demographic profile of a person affects their vulnerability to disaster based on:

  • Population Density
  • Distribution of Population
  • Wealth
• The type of hazard that interferes with the body’s ability to transport and utilize oxygen, or particle matters have adverse effects on the human body is Atmospheric hazards
• The impacts of hazard applicable in a scenario with Super typhoon Haiyan in Tacloban City include:

  • Physical Impact
  • Social Impact
  • Economic Impact
• To determine if impacts are environmental in context, it should affect:

  • The infrastructures
  • The flora and fauna
  • The job and properties of man
• The boundary present in an area with plates sliding apart forming a narrow rift valley and geysers is Divergent boundaries
• The difference between lava and lahar is:

  • Lava is molten rocks that flow out of a volcano or volcanic vent; Lahar is low density flows of pyroclastic material
• Hazards related to a recent volcanic eruption include:

  • Floods after the volcanic eruption
  • Lahars being present and affecting agricultural lands
  • Earthquakes are more frequent during and after the eruption
• A FALSE statement about an impending volcanic eruption is:

  • Decrease in the temperature of hot springs, wells, craters, lakes near the volcano
• The BEST course of action for an elderly man noticing increased steaming activity in a nearby volcano is to:

  • Wear a N-95 respirator/mask when going outside
• A landslide is defined as the mass movement of rock or debris down a slope
• Signs of a possible sinkhole include:

  • Cracks in the pavements are now visible
  • Foundations of some infrastructures are now slant
  • Small ponds appearing after a rainfall
• In a disaster readiness plan before a volcanic eruption, the course of action should include:

  • Preparation of necessary things
  • Preparation of evacuation route
• A warning sign of a landslide includes:

  • Cracks in the pavements are now visible
  • Foundations of some infrastructures are now slant
  • Small ponds appearing after a rainfall
• To prove that a landslide is anthropogenic, a geologist would look for:

  • Cracks in the pavements are now visible
  • Foundations of some infrastructures are now slant
  • Small ponds appearing after a rainfall
• The hazard classification of the Taal volcano eruption affecting 736,000 people in CALABARZON is Geological Hazard
