Disaster Readiness And Risk Reduction Flashcards
Any occurrence that causes damage, ecological disruption, loss of human life, or deterioration of health and health services on a scale.
Disaster
Give the 4 effects of a disaster
- Physical
- Social
- Economic
- Environmental
Effects of a disaster that shows; Poor design and construction of buildings, Unregulated land use planning, Use of substandard materials
Physical
Effects of a Disaster that shows; Poverty and inequality, Social status, Disability and age, Marginalization, Discrimination by gender
Social
Effects of a disaster that shows; Vulnerable rural livelihoods, Dependence on single industries, Globalization of business and supply chains
Economic
Effects of a Disaster that shows; Poor environmental management, Overconsumption of natural resources, and Climate change
Environmental
This is a situation or an occurrence with the CAPACITY TO BRING DAMAGE TO LIVES, properties, and the environment.
Hazard
What are the 3 types of hazards?
- Natural Hazards
- Human-made hazards
- Socionatural hazards
(Types of hazards) Natural phenomena that pose threats or cause negative impacts to people and property.
Natural Hazards
(Types of Hazards )Includes civil conflict, displacement due to development projects, environmental degradation, and industrial technological hazards.
Human Made Hazards
(Types of hazards) Most events are a combination or interplay of both natural and human-made factors
Socionatural Hazards
TRUE OR FALSE: There is no such thing as a natural disaster, only natural Hazards
TRUE
TRUE OR FALSE: A natural disaster becomes a hazard when it combines with exposure and vulnerability to cause loss of life, hurt and injury to people, along with economic loss.
FALSE
The potential to harm people or cause property damage, social and economic disruption.
Hazard
Location and how directly affected people from hazards.
Exposure
Age, gender, social status, disability, and people who are more susceptible to hazards.
Vulnerability
Expressed as the likelihood of loss of life, injury or destruction, and damage FROM A DISASTER in a given period.
Disaster Risk
FILL IN THE BLANKS:
A combination of _ _ _ _ _ _ × _ _ _ _ _ _ _ _ × _ _ _ _ _ _ _ _ _ _ _ _ _ = DISASTER RISK
Hazard x Exposure x Vulnerability
A sudden and violent shaking of the Earth’s surface caused by the movement of tectonic plates beneath the Earth’s crust.
Earthquake
(ANATOMY OF AN EARTHQUAKE) A fracture in the rocks that make up the Earth’s crust.
Fault Line
(ANATOMY OF AN EARTHQUAKE) The point at the surface of the Earth above the focus.
Epicenter
(ANATOMY OF AN EARTHQUAKE) The point within the Earth where an Earthquake rupture starts.
Focus
(ANATOMY OF AN EARTHQUAKE) Waves that transmit the energy released by an earthquake.
Seismic Wave
(TYPES OF FAULT) Rocks are sliding past one another on a horizontal plane.
Normal Fault
(TYPES OF FAULT) Two blocks of crust pulling apart and extending the crust into a valley, creating space.
Strike-Slip Fault
(TYPES OF FAULT) Also known as thrust fault, the slide one block of crust on top of another.
Reverse Fault
The energy released by an earthquake at the focus
Magnitude
An INSTRUMENT used to calculate magnitudes
Seismograph
A scale for MAGNITUDE shit
Mercalli Scale
A scale for INTENSITY shit
Richter Scale
It is the strength of an earthquake perceived and felt by people in a certain locality. Generally higher near the epicenter.
Intensity
TRUE OR FALSE: Intensity is generally higher near the epicenter.
TRUE
(EARTHQUAKE HAZARDS) Disruptive up, down and sideways movement of the ground during an earthquake.
Ground Shaking
(EARTHQUAKE HAZARDS) Deformation on the ground that marks the intersection of the fault with the earth’s surface
Ground Rupture
(EARTHQUAKE HAZARDS) It is a process caused by water pressure which makes soil more compact. It decreases the ground’s ability to support structures.
Liquefaction
(EARTHQUAKE HAZARDS) Down slope movements of rocks and other debris commonly triggered by strong shaking.
Landslide
(EARTHQUAKE HAZARDS) a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean.
Tsunami
Fault that is expected to generate a 7.2 magnitude can yield an intensity 8 earthquake that can affect Metro Manila
and nearby regions of Central Luzon and CALABARZON
West Valley Fault
Fascinating geological features that are formed when molten rock, ash, and gas escape from the Earth’s surface.
Volcano
Observable facts that are arising due to volcanic activity such as eruption.
Volcanic Hazards
One of the most dangerous natural events because of the different hazards: lahar, lava flows, ash falls, pyroclastic flows, debris avalanches, and emission of volcanic gases.
Volcanic Eruption
(SIGNS OF VOLCANIC ERUPTION) Increase in the frequency of volcanic quakes with rumbling sounds occurrence of volcanic tremors.
Earthquake
(SIGNS OF VOLCANIC ERUPTION) Increased STEAMING activity; change in color of steam from white to gray due to entrained ash.
Steam
(SIGNS OF VOLCANIC ERUPTION) Ground swells (or inflation), ground tilt and ground FISSURING due to magma intrusion.
Fissure
(SIGNS OF VOLCANIC ERUPTION) It is due to the presence of magma at or near the crater.
Crater Glow
(SIGNS OF VOLCANIC ERUPTION) Noticeable increase in drying up of vegetation around the volcano’s upper slopes
Dry Land
Give the 5 signs of volcanic eruption
Earthquake, Steam, Fissure, Crater Glow, Dry Land
(POTENTIAL VOLCANO-RELATED HAZARDS) a fast-flowing, destructive volcanic mudflow. It typically consists of a mixture of volcanic ash, debris, and water that originates on the slopes of a volcano, often triggered by heavy rainfall
Lahar Flow
POTENTIAL VOLCANO-RELATED HAZARDS) occurs when a volcano erupts, releasing fine particles of volcanic ash into the atmosphere. These particles can be carried by wind and fall to the ground over a wide area.
Ash Fall
POTENTIAL VOLCANO-RELATED HAZARDS) fast-moving, highly destructive mass of hot gas, ash, and volcanic rock fragments that flows down the sides of a volcano during an explosive eruption.
Pyroclastic Flow
POTENTIAL VOLCANO-RELATED HAZARDS) large volcanic rock fragments ejected during explosive volcanic eruptions. These fragments can vary in size from small rocks to boulders and are propelled into the air by volcanic explosions.
Ballistic Projectile
POTENTIAL VOLCANO-RELATED HAZARDS) movement of molten rock down the slopes of a volcano during an eruption. Moves relatively slowly compared to other volcanic hazards.
Lava Flow
