• GEOLOGICAL HAZARD- associated with earth materials such as toxic materials or earth processes which include landslides, earthquakes, sinkholes and many more.
• LANDSLIDE- rock, dirt, or debris falling down a sloping section of land
• GEOLOGY-is one of the three major cause of landslide where layers of earth has weakened or stiffened in some part
• MORPHOLOGY - is one of the three major cause of landslide where soil or rock has weakened through loss of vegetation or root system which holds the soil in place
• HUMAN ACTIVITY- is one of the three major cause of landslides that refers to agriculture and construction
• RAINFALL-INDUCED LANDSLIDE- occurs due to prolonged or heavy rainfall, increasing the weight of the land mass
• THE IMPENDING SIGNS OF RAINFALL-INDUCED HAZARD •Unusual noises, such as breaking trees, or knocking boulders together •Slight rumbling sound that rises in amplitude is noticeable. •Rapid rise in water levels of the creeks
• SINKHOLE- depression or hole caused by the collapse of the surface layer of the ground.
• SOLUTION SINKHOLE- is a type of sinkhole when rainwater dissolves rock beneath a thin layer of soil
• COVER SUBSIDENCE SINKHOLE- is a type of sinkhole that occurs when loose soil settles into cracks in the bedrock
• COVER COLLAPSE SINKHOLE- is a type of sinkhole that occurs suddenly when deep layers of soil collapse into voids formed by eroded bedrock
• GEOLOGICAL HAZARD MAP- showing the areas that are vulnerable to earthquake threats, volcanic eruptions, and landslides.
• MITIGATION FOR RAINFALL-INDUCED HAZARD- studying rainfall patterns, type of soil, land characteristics and flow of nearby bodies of water. This information can be gathered from a landslide geologic map.
• HYDROMETEOROLOGICAL HAZARD- process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, damages, and loss of livelihood and services
• Hydrometeorology- branch of meteorology and hydrology that studies the transfer of water and energy between the land surface and the lower atmosphere
• Hazard- any source that can cause harm or damage to humans, property or the environment.
• TYPHOON- large and destructive storm that commonly occurs in the Philippines or the South China Sea. Typhoon wind speed can be greater than 118kph
• HEAVY RAINFALL- Characterized by heavy rain, thunder, lightning, and the possibility of tornadoes
• SIGNS OF HEAVY RAINFALL: darkening skies, lightning, and strong winds.
• FLASH FLOODS- Local floods of short duration caused by heavy rainfall
• SIGNS OF FLASH FLOOD- continuous storms, distant thunder, rapidly rising water levels, muddy water, and the presence of debris.
• STORM SURGE- It is an escalating seawater to the coast above normal sea level.
• SIGNS OF STORM SURGE- Cumulonimbus darker sky, low pressure strong winds, and rising of seawater.
• EL NINO- climate phenomenon that occurs when a vast pool of water in the eastern tropical Pacific Ocean becomes abnormally warm. Under normal conditions, the warm water and the rains it drives are in the western Pacific
• SIGNS OF EL NINO- Hot weather, high pressure, change in temperature and gradually drying of land.
• LA NINA- strong winds blow warm water at the ocean's surface from South America to Indonesia. As the warm water moves west, cold water from the deep rises to the surface near the coast of South
• SIGNS OF LA NINA- Cooling of sea surface temperatures in the tropical Pacific, which occurs roughly every three to five years, lasting from 6 to 24 months.
• TORNADO- characterized by their funnel-shaped clouds and violently rotating winds.
• SIGNS OF TORNADO- The sky may take on a dark or greenish hue, often indicating the presence of severe weather.
• HAIL- form of precipitation that comes the form of balls or irregular lumps of ice. They can vary in size from small pea-sized hail to very large hailstones several inches in diameter
• SIGNS OF HAIL- often accompanied by intense thunder and lightning due to the strong convective forces within the storm.
• Fire- General combustion phenomenon releasing heat, light, and byproducts
• Forest Fire- Uncontrolled fire spreading through forests and grasslands
• Wildfire Hazard- Uncontrolled fires spreading rapidly due to dry conditions, high winds, or lightning strikes
• Arson- Deliberate setting of fires with malicious intent, posing a significant fire hazard and criminal offense.
• Conduction- Heat transfer through direct contact between objects or substances.
• Convection- Heat transfer through the movement of fluids
• SIGNS OF TYPHOON- increased ocean swell, a drop in barometric pressure, and high wind speeds.
