Study Notes
Geological Hazards
-
Geological hazards are processes causing loss of life, injury, property damage, and economic disruption.
-
Geological hazards include earthquakes, liquefaction (soil), tsunamis, and ground shaking.
Earthquakes
-
Earthquakes are caused by stress in the Earth's interior from moving tectonic plates.
-
Stress buildup eventually results in fractures, causing rock masses to shift.
Liquefaction
- Liquefaction is a process where soil loses its strength and stiffness due to vibrations, commonly during an earthquake.
Tsunamis
- Tsunamis are a series of large waves caused by the displacement of water in a body of water, often by an earthquake or volcanic eruption.
Ground Shaking
- Ground shaking is a consequence of the movement of the earth's ground caused by earthquakes.
Mass Movement
- Mass movement is the downslope movement of rock, debris, or earth; examples include landslides, mudslides, and avalanches.
Landslides
- Landslides are the movement of a mass of rock, debris, or earth down a slope.
Mudslide/Debris Flow
- Mud/debris flows are fast-moving landslide types that tend to flow in channels.
Avalanche
- Avalanches are masses of snow, ice, and rocks that fall rapidly down a mountainside.
Volcanic Eruptions
-
Volcanic eruptions involve the expulsion of lava, ash, and gases from a volcanic vent.
-
Lahars, volcanic mudflows, are a consequence.
Signs of Landslides
- Experts note warning signs for impending landslides.
Signs of Earthquakes
- There's no confirmed way to predict earthquakes.
Volcanic Signs
- Volcanoes often provide warnings before an eruption, including increased earthquake activity and ground deformation.
Geological Maps
- Geological maps represent rock types, contacts, folds, faults, and resources.
Color on Geological Maps
- Colors represent different rock formations.
Lines and Symbols on Geological Maps
- Lines and symbols show tectonic structures, contact points, and other features.
Mitigation Strategies
- Prevention strategies should consider land use, building codes, infrastructure, and environment.
Hydro-meteorological Hazards
- Extreme weather and climate events are hydro-meteorological hazards, including floods, droughts, hurricanes, tornadoes, landslides, and mudslides.
Typhoon
- Typhoons, common in the Philippines, are low-pressure areas over warm water in the western Pacific, resulting in storm surges and heavy rain.
Flood/Flash Floods
- Floods are inundation of normally dry land areas, and are often caused by storms, heavy rains, or tsunamis.
Storm Surge
- Storm surge is a rise in sea level due to cyclonic wind and atmospheric pressure.
Lightning/Thunderstorms
- Thunderstorms are characterized by cloud formations, darkening skies, lightning, and wind.
El Niño
- El Niño is a climate pattern with unusually warm water in the Pacific, impacting weather globally.
El Niño Signs
- Hotter-than-normal temperatures, high pressure, and gradual drying of land.
Fire
- Fire is the rapid oxidation of a material resulting in heat, light, and products.
The Fire Triangle
- A fire needs oxygen, fuel, and heat to occur.
Fire Tetrahedron
- A fire requires fuel, oxidant, heat, and a chemical chain reaction to occur.
Fire Stages
- Fire goes through stages: incipient, growth, fully-developed, and decay.
Fire Extinguishers
- Different extinguishers are used for different fire types (A, B, C, D, K) and contain different agents.
Disaster Preparedness Steps
- Risk identification, risk analysis, risk prioritization, risk treatment, monitoring, and evaluating disaster risk management.
Disaster Risk Reduction
- Disaster risk reduction actions prevent disaster impacts by reducing vulnerabilities and increasing capacity to cope, and by mitigating disaster risks, minimizing losses.
