Hydrometeorological Hazards
Processes or phenomena of atmospheric, hydrological, or oceanographic in nature that can cause loss of life, damage to properties, socio-economic disruption, and environmental damage
Typhoons
Intense low-pressure system with a minimum sustained wind velocity of 35 kph
Thunderstorms
Localized storm cloud that produces lightning and thunder often brings heavy rain showers and strong winds
Storm Surges
Sudden rise of sea level above the normal level on the coast due to a drop in atmospheric pressure and the force of the wind as a tropical cyclone approaches the coast
Flooding
Abnormal progressive rise in the water level of a stream; may result in the overflowing by the water of the normal confines of the stream
El Nino Southern Oscillation
Climatic phenomenon characterized mainly by cyclic fluctuations of warm and cold sea surface temperatures and atmospheric pressure in the central and eastern Pacific
Tropical Cyclone
type of storm system that forms over warm ocean waters in tropical and subtropical regions
Tropical Depression
Tropical cyclone at 61kph or less
Tropical Storm
Tropical Cycone at 62-88kph
Severe Tropical Storm
Tropical Cyclone at 89-117kph
Typhoon
Tropical Cyclone at 118-220
Super Typhoon
Tropical Cyclone at more than 220kph
Philippine area of responsibility
Meaning of PAR
Public storm warning signals
Meaning of PSWS
Developing Stage
Towering cumulus cloud indicates rising air
Mature Stage
Most likely time for hail, heavy rain, frequent lightning, strong winds, and tornadoes
Dissipating Stage
Downdrafts, downward flowing air, dominate the storm
Riverine
a flood that occurs when rivers overflow their banks and flow into surrounding areas
El Nino
Warm water, weak trade winds, droughts
La Nina
Cool water, strong trade winds, lots of rain
9 Days
How long a typhoon may last
Volcano
A rupture in the earth’s crust
Magma
Molten rock found within Earth
Lava
Molten rock released from Earth’s mantle
Magma Chamber
Large underground pool of magma within the volcano
Crater
The opening at the top of a volcano
Main vent
Channel magma flows through to get to the surface
50
how many volcanoes erupt per year
Pacific ring of fire
Where 75% of volcanoes are
Hotspot
Columns of rising mantle materials that begin to melt as they rise to lower pressure and shallower depths
High pressure buildup
When does an eruption take place
Viscosity
A liquid’s resistance to flow
Composite volcano
Found on destructive plate margins and has a distinct conical shape
Shield Volcano
Found at constructive plate margins or at hotspots and has gentle sloping slides
Lava Flow
It is a mass of magma that flows down the slope (at a rate of 3km per day or 45km per hour) of a volcano
Volcanic Gases
Gases emitted by a volcano that include water vapor, carbon dioxide, sulfur dioxide, and hydrogen halides
Pyroclastic Flow
Hot, dry masses of volcanic fragmented materials that move along a slope. It is faster than lava flow. Ashy and grey at day, and glowing hot red at night
Tephra Falls
Showers of fine to coarse-grained volcanic materials and other airborne products of a volcanic eruption. Can reach several 100 kilometers away as it is carried by the wind
Ash
Less than 2mm
Lapilli
2-64mm
Blocks Projectiles
More than 65mm
Ballistic Projectile
it is a type of tephra fall wherein rocks are released into the air by an erupting volcano. It can land within 2km of the vent but can travel as far as 5km or further if the eruption is very explosive
Lahar
Flowing mixture of volcanic debris and water
Hot Lahar
Associated directly with volcanic eruption
Cold Lahar
Caused by heavy rainfall
