Typhoons
ORIGIN
late 16th century: partly via Portuguese
from Arabic ṭūfān (perhaps from Greek
tuphōn ‘whirlwind’); reinforced by Chinese
dialect tai fung ‘big wind’.

4. An earthquake is a sudden release of
energy along a fault in the Earth's crust.
a sudden and violent shaking of the ground,
sometimes causing great destruction, as a
result of movements within the earth's crust
or volcanic action.
Earthquake
It poses a severe threat because of its
irregular intervals and difficulty to forecast.

5. Volcanic eruptions occur when molten
material from the Earth's interior is
extruded to the surface.
Volcanic
Eruption
Avalanches of hot materials, release of
toxic gas, and lava flows make volcanic
eruptions dangerous.

6. Did You
Know?
Earthquakes and volcanoes commonly
occur in the boundaries of tectonic
plates.
The Pacific Ring of Fire, for example, is
a horseshoe-shaped belt in the Pacific
Ocean where active volcanoes and
frequent earthquakes occur.

7. Floods and flashfloods are common
products of torrential rains especially if it
occurs after a long period of dry
conditions.
Flood/
Flashflood
Dam breaks can also result to flooding, and
can severely affect the communities
nearby.

8. landslides
A landslide is the movement of rock,
earth, or debris down a sloped
section of land.
Landslides are caused by rain,
earthquakes, volcanoes, or other
factors that make the slope unstable
Landslides have three major causes:
geology, morphology, and human
activity..

9. HISTORY OF
NATURAL DISASTER
IN THE PHILIPPINES

10. Luzon Earthquake
1645. The magnitude
7.5 earthquake that
struck Luzon killed 600
people and greatly
damaged churches
including the Manila
Cathedral. The
earthquake was
considered the
strongest to hit the
country since the
Spanish conquest.

11. Luzon Earthquake. (July
16, 1990) An earthquake
of 7.8 magnitudes and
intensity of 9 struck
Luzon. The epicenter was
Nueva Ecija however the
ground rupture
stretched up to the
province of Aurora. The
earthquake killed an
estimated 1,621 people
and collapsed several
buildings including Hyatt
Terraces Baguio Hotel
and Hotel Nevada also in
Baguio.

12. Taal Volcano 1754
Eruption. The
volcano erupted for
7 months burying 4
towns in Batangas.
As much as 40
inches of ash were
recorded in some
areas.

13. Taal Eruption ( Jan.
30, 1911). The very
explosive eruption
wiped out 7
barangays on the
island and killed
more than 1,000
people from
scalding by hot
steam or hot mud.
The eruption was
one of the most
notable in the
volcano’s
recorded history.

14. Taal Eruption
(1965). The
eruption
devastated
villages on the
lake shore and
killed an
estimate of 100
people.

15. Mayon Eruption ( Feb. 1,
1814). The eruption was
the strongest recorded
to date of the Mayon
volcano. The volcano
erupted
characteristically dark
ash and car-sized
boulders toward the
town of Cagsawa
therefore burying it
along with the Cagsawa
Church which its ruins
now a tourist attraction.
An estimate of 2,000
people were killed
during the eruption.

16. Hibok-Hibok Eruption.
A volcanic fissure
opened following days
of earthquakes and
subterranean
rumblings. From the
opening, lava was
continuously spewed
and drained into the
sea for four years
destroying the town
and eventually forming
a cone which is now
known as Mt. Vulcan.
The eruption caused
the Sunken Cemetery
and Gui-ob Church
ruins, both are now
tourist attractions in
Camiguin.

17. Panay Earthquake. (
Jan. 25, 1948) While
recovering from the
effects of World War
II, Panay was hit by
an earthquake with
an estimated

people and injured
1,274 more..

19. Pinatubo Eruption.(
June 12-15, 1991) A
series of eruptions
occurred after being

of years. The eruption
was worsened by
Typhoon Yunya
(Typhoon Diding)
therefore causing a
messy rain of mud and
massive lahars and
killing more than 800
people. The eruption
was the second-largest
volcanic eruption in the
world during the 20th
century.

20. Mindoro Earthquake.(
Nov. 15, 1994) The
earthquake had a
magnitude of 7.1 and
intensity of 7. With the
epicenter in Verde Island

and landslides therefore
killing 78 people and
damaging almost 8,000
houses.

21. Samar Earthquakes. (
April 21, 1995) A series
of earthquakes struck
Samar and generated a

the largest earthquakes
have magnitude
between 7 to 7.3..

22. The Philippines was hit
with a succession of
three typhoons Yvette
(Oniang), Zack (Pepang),
and Angela (Rosing). The
latter intensified into a
super typhoon and had
the third highest wind
speeds recorded in the
Philippines. Overall, the

most intense and
costliest typhoons in the
Philippines.
( Oct. 18, 2010)

29. Tropical Storm Washi

and deadliest typhoon
on record with death toll
reaching more than
6,000.
(Nov. 8, 2013)

34. Typhoon Haima (Super

35. 2019 Cotabato
earthquakes
The 2019 Cotabato
earthquakes were an
earthquake swarm which
struck the province of
Cotabato on the island of
Mindanao in the
Philippines in October
2019.[6] Three of these
earthquakes were above

magnitude scale with a
Mercalli intensity of VIII.
More than 40 people have
been reported dead or
missing and nearly 800
were injured as a result of
these events.
(Oct.16 , 29, Dec. 15
2019)

36. Super Typhoon Rai, locally
referred to as “Odette”
Super Typhoon Rai made nine
landfalls on 16–17 December
2021, severely disrupting the
livelihoods of vulnerable
farmers and fishers and
compounding the impacts of
other climate-induced shocks
and the coronavirus disease
2019 pandemic. Beyond its
immediate impacts, Super
Typhoon Rai adversely affected
the food security of households
who depend on farming and
fishing for their primary or
secondary source of livelihoods
as their productive capacities
decreased and their incomes
were disrupted.
(Dec. 16-17, 2021)

37. Over the last two days
more information has
started to emerge
about the landslides
triggered by Tropical
Storm Megi / Agaton,
which caused mayhem
on the island of Leyte in
the Philippines on 11
April 2022. The latest
news on casualties is
that at least 123 people
were killed, the majority
in landslides, but more
remain missing.
Eighty-six of the casualties
were in Baybay, a
mountainous area prone to
landslides in central Leyte
province, where 236 people
were also injured, the city
government said in a
report.

38. Some areas can be more
affected by a hazard or
disaster than other areas due
to the following factors:
Vulnerability
to Hazards
and Disasters
Proximity to a
hazardous event
High population
density in an area
Lack of public education
and awareness
Lack or non-existent
early warning systems
