Hydrometeorological hazard

- 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.

2
New cards

• Typhoon

• Flood

• Thunderstorm

• Flashflood

• El Niño

• La Niña

TYPES OF HYDROMETEROLOGICAL HAZARD:

3
New cards

Philippines

ranks among the world's most

disaster-prone countries.

4
New cards

"Pacific

Ring of Fire," and in the geologically unstable

region between the Pacific and Eurasian

tectonic plates.

It is highly prone to

natural disasters, particularly typhoons, floods,

landslides, volcanic eruptions, earthquakes, and

tsunamis, lying as it does in the typhoon belt, in

the active volcanic region known as the _______

5
New cards

Typhoon

- A tropical cyclone is a rapidly rotating storm

system characterized by a low-pressure center, a

closed low-level atmospheric circulation, strong

winds, and a spiral arrangement of

thunderstorms that produce heavy rain and/or

squalls

6
New cards

High Pressure

- Cold air

- Air gets denser and heavier

7
New cards

Low Pressure

- Warm air

- Air becomes less dense and lighter

8
New cards

Inter Tropical Convergence Zone (ITCZ)

is

a belt of low pressure which circles the Earth

generally near the equator where the trade

winds of the Northern and Southern

Hemispheres come together.

9
New cards

increasing ocean swell, falling

barometric pressure, and strengthening winds in

the days leading up to landfall.

Signs of an approaching typhoon or hurricane

include _____

10
New cards

PAGASA

provides weather forecasts and tropical

cyclone warnings, flood bulletins and advisories,

hydrological, climatological and weather

forecasts.

11
New cards

Public Storm Warning Signals

are raised to warn

the public of incoming weather disturbances.

Once a Storm Signal is raised, conditions are not

yet necessarily felt in the given area.

12

Northeast Pacific Ocean and Atlantic Oceam

13

15
New cards

thunderstorm

also known as an electrical

storm or a lightning storm

16
New cards

thunderstorm

characterized by the presence of lightning and

its acoustic effect on the Earth's atmosphere,

known as thunder.

17
New cards

thunderstorm

are sometimes called

thundershowers

18
New cards

LIGHTNING

THUNDER IS CAUSED BY ______

19
New cards

channel

When a

lightning bolt travels from the cloud to the

ground it actually opens up a little hole in the

air, called a _______.

20
New cards

Flash flood

is a flood caused by heavy or

excessive rainfall in a short period of time,

generally less than 6 hours.

21
New cards

Flooding

is a longer term event than flash

flooding: it may last days or weeks

22
New cards

El Niño and La Niña

are a global climate

phenomenon caused by cyclical shifts in the

water temperature of the Pacific Ocean.

23
New cards

El Niño

- is the warming phase of water temperatures

around the Pacific Equator.

24
New cards

La Niña

- is the opposite of El Niño: an intensification

of normal weather patterns. This causes

ocean surface temperatures to cool down as winds strengthen and blow warm water

towards the west.

25
New cards

Storm surge

is the abnormal rise in seawater

level during a storm, measured as the height

of the water above the normal predicted

astronomical tide.

26
New cards

Man-Made Hazards

- events or conditions that are caused by

human activities and have the potential to

cause harm to people, property, or the

environment

27
New cards

Man-Made Hazards

- often preventable or controllable

28
New cards

• Technological Hazards

• Sociological Hazards

• Environmental Hazards

Types of Man-Made Hazards

29
New cards

Technological / Industrial Hazards

- Hazards originating from technological or

industrial accidents, dangerous procedures,

infrastructure failures or specific human

activities.

30
New cards

Chernobyl Accident, 1986

was the

result of a flawed reactor design that was

operated with inadequately trained

personnel. The resulting steam explosion

and fires released at least 5% of the

radioactive reactor core into the

environment, with the deposition of

radioactive materials in many parts of

Europe.

31
New cards

fire, power outages, dam failure,

transport accidents, infrastrature failure

Technological / Industrial Hazards Examples:

32
New cards

Sociological Hazards

- Hazards due to sociological causes, also a

sub-class of anthropogenic hazards.

33
New cards

crime, terrorist, threats, and war.

Sociological Hazards Examples:

34
New cards

Battle of Marawi

- In May 2017, Muslim militants acting in the

name of the Islamic State (ISIS) seized

Marawi, a lakeside economic hub in the

Lanao del Sur province of Mindanao, the

second-largest island in the Philippines. It

took the Filipino military five months to

regain control of the city.

35
New cards

Environmental hazards

are hazards that

affect biomes or ecosystems

36
New cards

oil spills, pollution, slash and burn

deforestation, ground fissures, build-up of

atmospheric carbon dioxide

Environmental hazards Examples:

37
New cards

Guimaras Oil Spill

- On August 11, 2006, an oil spill occurred in

Panay Gulf when the oil tanker, MT Solar 1,

in the Philippines, causing what is considered

sank off the coasts of Guimaras and Negros

to be the worst oil spill in the country's

history

38

Preparedness and Risk Reduction

39
New cards

Disaster

- It is often described as a result of the

combination of several things: the exposure

to a hazard.

40
New cards

Prevention

- A pre-event element of DRR which is the

outright avoidance of adverse impacts of

hazards and related disasters.

41
New cards

Response

- A post event element with the provision of

emergency services and public assistance

during or immediately after a disaster.

42

adjustment in natural or human systems in

response to actual or expected climatic

stimuli or their effects.

43
New cards

Disaster risk reduction (DRR)

- a term used for reducing and preventing

disaster risks. It is founded on the principle

that while hazards are inevitable, its adverse

effects like lost lives and/or destruction of

property are not.

44
New cards

exposure to a hazard; vulnerability; capacity

Disasters are often described as a result of the

combination of several things:

45
New cards

Disaster Risk = Hazard x Exposure x Vulnerability / Capacity
