• LANDSLIDE - also called “landslip”, is a

  ground movement on a sloping terrain.
• WATER - is a natural agent for erosion, and

  if rain of any source of water

  frequently flows down a sloping

  area, the gravitational descent of

  loosened soil makes it possible for

  landslide to occur.
• Sinkholes - Are depressions or holes on the ground that resulted from the collapse of the surface layer of

  the soil.
• FOR LANDSLIDES, In areas that are susceptible to landslides, an Abney level or a laser rangefinder equipped with with a tiltmeter is used to measure the slope angle, soil compaction, and soil

  strength of an area
• FOR SINKHOLES, Are validated using Ground-Penetrating Radar (GPR) to provide images of subsurface ground. It can detect the type of objects, changes in material, and void and cracks under a layer of soil
• Hydrometeorological hazards - Are dangers associated with the

  natural processes or phenomena involved in the transfer of water and energy between the land surface and the lower atmosphere.
• Typhoon - Are intense circulating winds with

  heavy rain over tropical waters and land
• UP TO 61 KPH Tropical Depression
• 62 TO 88 KPH Tropical Storm
• 89 TO 117 KPH Severe tropical storm
• 118 TO 220 KPH Typhoon
• EXCEEDING 220 KPH Super typhoon
• Thunderstorm - also known as

  electrical storm characterized by

  heavy rain with presence of thunder

  and lightning.
• flood - is the presence of

  excessive water on a supposedly

  dry land.
• flash flood - is a rapid flow of water on saturated soil or dry soil or any foundation that has poor absorption capability.
• storm surge - is an abnormal rise

  in coastal waters due to a massive

  force from the sea or from the air

  above the sea.
• tornado - is a rapidly rotating

  column of air that is in contact with

  the air and land.
• The El Niño phenomenon refers to the large-scale warming of the ocean and atmosphere across the central and east-central Equatorial Pacific.
• La nina - The sea surface temperatures

  during this period become lower by

  3-5 degrees Celsius.
• Doppler Radar - Used to measure important weather

  parameters such as amount of

  rainfall and direction, speed and

  intensity of winds.
• Automated rain gauge - This is used to detect for possible

  flooding and flash floods.
• Fire - It is the process of rapid oxidation of

  any material resulting in burning.
• oxidation - It means that oxygen molecules

  interact with different substances in

  the environment, making it unstable

  and thus creating a reaction.
• Fire triangle - It is a model that shows the three

  essential components that when

  present together can start a fire and

  sustain it.
• fuel - Fire needs a fuel source or

  combustible material in order to

  burn.
• heat - This is needed to start and continue

  the combustion process
• oxygen - This constitutes about 21% of the air

  around us and it reacts with flammable

  vapors given of by fuels, and the

  reaction releases heat.
• combustion - It happens when flammable vapor

  mixes with air and is ignited by a

  spark or flame.
• two causes of fire: natural and man-made
• burn - They are tissue injuries caused by

  heat, electricity, or chemicals
• first-degree burn - It affects only the outer layer of the

  skin called the epidermis.
• second-degree burn - The depth of burn has reached into

  the dermis in this degree.
• third-degree burn - This degree of burn is classified

  when the burn reaches the

  underlying fat tissue.
