DRRR Flashcards
(38 cards)
A ground movement on a sloping terrain.
LANDSLIDE
depressions or holes on the ground that resulted from the collapse of the surface layer of the soil.
SINKHOLES
It occur in areas where the soil foundation is made of soft minerals and rocks such as silicate materials, salt beds, or any acidic rocks.
SINKHOLES
The geographic location of the Philippines does not only pose geological threats but also…
HYDROMETEOROLOGICAL HAZARDS
Where is the Philippines located?
NORTHERN HEMISPHERE (above the equator)
The area in equator is known as…
INTERTROPICAL CONVERGENCE ZONE (ITCZ)
What are the 8 types of Hydrometeorological Hazards?
-Typhoons
-Thunderstorms
-Flash Floods
-Floods
-Storm surges
-Tornadoes
-El Niño
-La Niña
it is the dangers associated with the natural processes or phenomena involved in the TRANSFER OF WATER and ENERGY between the land surface and the lower atmosphere
HYDROMETEOROLOGICAL HAZARDS
The intense circulating winds with heavy rain over tropical waters and land.
TYPHOONS
it is known as electrical storm.
THUNDERSTORM
A storm characterized by heavy rain with the presence of thunder and lightning.
THUNDERSTORM
the presence of excessive water on supposedly dry land. It can caused by continuous heavy rain or poor drainage.
FLOOD
A rapid flow of water on saturated soil or dry soil or any foundation that has poor absorption capability.
FLASH FLOOD
Usually caused by extensive rainfall but can also be induced by man-made structures such as water overflows from a dam.
FLASH FLOOD
An abnormal rise in coastal waters due to a massive force from the sea or from the air above the sea.
STORM SURGE
A rapidly rotating column of air that is in contact with the air and land.
TORNADO
It usually associated with the warming of the central and tropical waters of the Pacific Ocean.
EL NIÑO
the cooling of the same areas in s different season.
LA NIÑA
Refers to the large-scale warming of the ocean and atmosphere the central and east-central Equatorial Pacific.
EL NIÑO
This event begins with the heating up of the Pacific Ocean near the equator.
EL NIÑO
begins in the eastern part of the Pacific Ocean. Similar to the location of El Niño. The sea surface temperatures during this period become lower by 3-5 degrees Celsius.
LA NIÑA
2 tools for monitoring Hydrometeorological Hazards
-Doppler Radar
-Automated rain gauge
used to measure important weather parameters such as amount of rainfall and direction, speed, and intensity of winds. These data are used to forecast weather conditions and upcoming typhoon weeks before the occurrence
DOPPLER RADAR
Usually installed in telecommunication cell sites to observe and locate areas with excessive amount of rainfall. This used to detect for possible flooding and flash floods.
AUTOMATED RAIN GAUGE
