DRRR Flashcards
refers to a natural event or process that originates from within the Earth and has the potential to cause harm or damage to human life, property, and the environment.
GEOLOGICAL HAZARD
form through a geological process known as karstification, which occurs in areas where the bedrock is made of limestone, gypsum, or other soluble rocks.
SINK HOLE
can cause extensive damage to property, infrastructure, and natural landscapes, and they pose a significant threat to communities living in hilly or mountainous regions.
RAINFALL-INDUCED LANDSLIDE
also known as mudflows, are fast-moving landslides composed of a mixture of water, mud, rock, and debris. They often occur in steep terrains and are triggered by heavy rainfall, rapidly mobilizing loose materials down slopes.
Debris Flow:
are sudden and rapid movements of individual rock blocks or boulders from steep cliffs or slopes. Heavy rainfall can saturate the rocks, reducing friction and triggering them to detach and fall.
Rockfall:
are volcanic mudflows or debris flows that occur on the slopes of volcanoes, often triggered by heavy rainfall or the melting of snow and ice during volcanic eruptions. They can be highly destructive and travel at high speeds, carrying volcanic ash, rocks, and debris.
Lahar:
Process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, Injury or other health impacts property damage, loss of livelihoods and services social and economic disruption, or environmental damage.
HYDROMETEOROLOGICAL HAZARDS
is an abnormal rise of water generated by a storm, over and above the predicted astronomical tides.
STORM SURGE
is a rapid flooding of low- lying areas: washes, rivers, dry lakes, and depressions.
FLASH FLOOD
is defined as a tropical cyclone with the maximum wind of 34 knots or higher.
TYPHOON
refers to the periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific.
LA NIÑA
occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal El Niño is a weather pattern that occurs in the Pacific Ocean
EL NIÑO
is a localized storm accompanied by lightning and thunder.
THUNDERSTORM
significantly impact disaster readiness and risk reduction efforts, requiring meticulous attention within comprehensive emergency plans.
