2. EARTHQUAKE

3. ACTIVATE??????
1.Have you ever experienced an
earthquake? If so, where were you and
what was it like?

4. ACTIVATE??????
2.How did you feel during the
earthquake? What were your immediate
actions or reactions?

5. ACTIVATE??????
3.How did your community or city
respond to the earthquake? Were there
any emergency procedures in place?

6. EARTHQUAKE
The Earthquake is any sudden shaking of
the ground caused by the passage of
seismic waves through Earth’s rocks.

7. SEISMOLOGY
Seismology is the study of earthquakes and
seismic waves that move through and around
the Earth. A seismologist is a scientist who
studies earthquakes and seismic waves.

8. SEISMIC WAVE
Seismic waves are caused by
the sudden movement of
materials within the Earth,
such as slip along a fault
during an earthquake.
Volcanic eruptions,
explosions, landslides,
avalanches, and even rushing
rivers can also cause seismic
waves.

9. SEISMIC WAVE
Earthquakes send out seismic energy
as both body and surface waves. The
two main types of waves are body
waves and surface waves.
• Body waves can travel through the
Earth's inner layers.
• Surface waves can only move along
the surface of the planet like ripples
on water.

10. SEISMIC WAVE
Primary waves can travel through liquid and solids.
Secondary waves can travel through solids only.

11. Surface waves can only move along the
surface of the planet like ripples on water.
Love Waves—surface waves that move parallel
to the Earth's surface and perpendicular to
the direction of wave propagation.
Rayleigh Waves—surface waves that move in
an elliptical motion, producing both a vertical
and horizontal component of motion in the
direction of wave propagation.
Surface WAVE

12. BODY WAVE
Body waves can travel through the Earth's
inner layers.
P waves - primary seismic waves. Move
fast back and forth such as compression
and expansion. Initial shaking felt during
earthquake.
S waves - secondary seismic waves. Move
slowly perpendicular to the direction of
wave propagation. Intense shaking and
are responsible for much of a damage.

13. Fault
Is a fracture or zone of
fractures between two
blocks of rock. These
blocks can move relative
to each other along the
fracture, which is the
reason why earthquakes
occur.

16. tRANSFORM BOUNDARIES
At transform boundaries, two plates slide
past each other horizontally. This horizontal
movement can cause earthquakes, but it
doesn't typically create volcanoes or cause
the formation of mountains. An example of a
transform boundary is the San Andreas Fault
in California.

17. Divergent Boundaries
At divergent boundaries, two tectonic
plates move away from each other. As the
plates separate, magma rises from the
mantle to fill the gap, creating new crust.
This can form underwater mountain ranges
known as mid-ocean ridges. An example of a
divergent boundary is the Mid-Atlantic
Ridge.

18. Convergent Boundaries
At convergent boundaries, two plates collide.
Depending on the types of crust involved
(continental or oceanic), this can lead to the
formation of mountains, the creation of
subduction zones (where one plate is forced
beneath another), or the formation of volcanic
arcs. The Himalayas are an example of a mountain
range formed by a convergent boundary between
the Indian Plate and the Eurasian Plate.

20. Intensity and
Magnitude

21. Intensity
This measures the effects of an
earthquake at specific places. The
intensity of an earthquake can vary
depending on the location's distance
from the epicenter, the depth of the
earthquake, and the local geological
conditions.

22. Magnitude
This measures the energy released at the
source of the earthquake. It is determined
from measurements on seismographs. The
magnitude of an earthquake is a single,
absolute value that does not vary
regardless of location.

23. What to Do
Before an
Earthquake

24. First aid kit, a battery-powered radio, a
flashlight, and extra batteries at home.
Learn first aid.
Learn how to turn off the gas, water, and
electricity.
Make up a plan of where to meet your
family after an earthquake.

25. Don't leave heavy objects on shelves
(they'll fall during a quake).
Anchor heavy furniture, cupboards, and
appliances to the walls or floor.
Learn the earthquake plan at your school
or workplace.

26. What to Do
DURING an
Earthquake

27. Stay calm! If you're indoors, stay inside. If
you're outside, stay outside.
If you're indoors, stand against a wall near
the center of the building, stand in a
doorway, or crawl under heavy furniture
(a desk or table). Stay away from windows
and outside doors.

28. If you're outdoors, stay in the open away
from power lines or anything that might
fall. Stay away from buildings (stuff might
fall off the building or the building could
fall on you).
Don't use matches, candles, or any flame.
Broken gas lines and fire don't mix.

29. If you're in a car, stop the car and stay
inside the car until the earthquake stops.
Don't use elevators (they may shut down).

30. What to Do AFTER
an Earthquake

31. Check yourself and others for injuries.
Provide first aid for anyone who needs it.
Check water, gas, and electric lines for
damage. If any are damaged, shut off the
valves. Check for the smell of gas. If you
smell it, open all the windows and doors,
leave immediately, and report it to the
authorities (use someone else's phone).

32. Turn on the radio. Don't use the phone
unless it's an emergency.
Stay out of damaged buildings.
Be careful around broken glass and
debris. Wear boots or sturdy shoes to
keep from cutting your feet.
Be careful of chimneys (they may fall on
you).

33. Stay away from beaches. Tsunamis and
seiches sometimes hit after the ground has
stopped shaking.
Stay away from damaged areas.
If you're at school or work, follow the
emergency plan or the instructions of the
person in charge.

34. What is
tsunami?

35. Tsunamis are giant waves
caused by earthquakes or
volcanic eruptions under the
sea.

42. ONE OF THE biggest TSUNAMI HAPPENED HERE
in philippines
It measured 8.0 on the moment magnitude scale occurring at a
depth of 20 km (12 mi). The initial earthquake was widespread and
was felt as far as the central Philippine islands of the Visayas. A
massive tsunami devastated 700 kilometers of coastline bordering
the Moro Gulf in the North Celebes Sea, resulting in destruction
and death in the coastal communities of the Sulu Archipelago,
southern Mindanao particularly the provinces of Sultan Kudarat
and Sarangani (formerly part of South Cotabato), and in the
Zamboanga Peninsula including Zamboanga City and Pagadian City.
