14. Lesson Objectives:
 Define tsunami.
 Distinguish between tsunami, tidal wave & storm
surge.
 Identify and recognize the natural signs of an
impending tsunami;
 Discuss how one may prepare and protect oneself in
case of a tsunami-generating earthquake.
 Prepare a plan on what to do before, during and after
tsunami.

15. Activity Time:
Activity # 1:
See the
difference

18. Activity #1:
TSUNAMI TIDAL WAVE STORM SURGE

19. Processing time!
What is TSUNAMI?
- is a series of giant waves commonly
generated by under-the-sea earthquakes and
whose heights could be greater than 5
meters.

20. Processing time!
TSUNAMI
- sea waves resulting from the disturbances
of ocean floor by an earthquake; it is a series
of giant waves commonly generated by
under-the-sea earthquakes.

21. Processing time!
TIDAL WAVE
- is a shallow water wave caused by the
gravitational interactions between sun,
moon, and Earth.

22. Processing time!
STORM SURGE
- is the abnormal rise in seawater level
during a storm, measured as the height of
the water above the normal predicted.

23. There two types of Tsunami
Local Tsunami
- are confined to coasts within a hundred kilometres of the
source usually earthquakes and a landslides. It can reach the
shoreline within 2 to 5 minutes.
Far Field or Distant Tsunami
- can travel from 1 to 24 hours before reaching the coast of the
nearby countries. These tsunamis are coming from the
countries bordering Pacific Ocean like Chile.

31. Signs of an impending tsunami
* Earthquake.
* See ocean water disappear from the
beach, bay or river or changes in water
level
* Hear unusual roaring sound.

33. Activity Time # 3:
MAKE A PLAN ON WHAT
ARE THE THINGS YOU
SHOULD DO BEFORE,
DURING AND AFTER
TSUNAMI

34. BEFORE:
 Find out if your home, school, workplace or other frequently
visited locations are in tsunami hazard areas. For high risks areas,
know the earthquake and tsunami plans for each locations.
 Contact your municipality to know the risks, evacuation and
alerting system in your community. Know the sound of the alert
and make sure all in your family are familiar with it and what to
do. Sign up for local alerts.
 Make a personalized preparedness emergency kit. Families should
be prepared to be self-sustaining for at least 3 days.

35. BEFORE:
 Kits should include practical items such as drinking water,
food, cash, and portable radio. However, they should also
include items that are unique to your own families’ needs.
This could include baby items, medical prescriptions, pet
food, etc.
 If you have already dipped into emergency kit and food
supply while staying at home, consider safely getting the
supplies to replenish it following your local public health
authorities’ guidelines for leaving your residence.

36. BEFORE:
 During the COVID-19 pandemic also add hygiene items such as
hand sanitizer and non-medical masks to your kit to keep your
family safe during an evacuation.
 Know the difference between tsunami watch and tsunami
warning. Tsunami warning means may have been generated and
could be close to your area. A full evacuation is suggested.
Tsunami watch means a tsunami has not yet been verified but
could exist and may be as little as an hour away. Stay alert for
more information.

37. BEFORE:
 Review evacuation plans with household members.
Be prepared ready to evacuate at a moment’s notice.
 Plan evacuation routes to areas 30 meters above sea
level or 3 k inland. If you can’t go as high and as far
away as you can. You should be able to reach your
safe location on foot with 15 minutes.

38. DURING
A strong earthquake lasting 20 seconds or
more near the coast.
A noticeable rapid rise or fall of coastal waters.
Coastal water making unusual noise. The
noise may sounds like an approaching train,
plan, or truck

39. DURING
Following an earthquake, move quickly to
higher ground away from the coast. In case of
a tsunami warning, be prepared ready to
evacuate at moment’s notice.
Follow posted evacuation routes, where
present. Take your animals with you but do
not delay your evacuation to collect them.

40. DURING
 A tsunami is a series of waves that can continue for
hours and next waves may be larger than the earlier
ones. Do not assume that after on wave, the danger is
over. If you cannot evacuate to higher ground,
evacuate vertically to a higher floor, onto a roof, up a
tree, or grab a floating object.
 If you are at sea, stay there. Boats are generally safer
in water deeper than 100 meters.

41. DURING
Watching a tsunami could put you in grave
danger. If you can see the wave, you are too close
to escape.
Monitor the tsunami’s progress and listen for
warnings or instructions from local officials. If
you are safe when the first the first tsunami hits,
stay put until authorities declare all is safe as
more waves may follow.

42. AFTER
 Be prepared for aftershocks, which could generate
another tsunami.
 Return home only after local officials tell you it is safe.
 Be aware of secondary effects. These include landslides,
contaminated water, mudflows, damaged bridges,
buildings, and roads and other hazards.

43. AFTER
 Do not light matcher or turn on lights or appliances
until you are sure there are no gas leaks or flammable
liquids spilled. Avoid use of contaminated water.
 Place help sign in your window if you need assistance.
 Experiencing a disaster is challenging enough, but
during the COVID-19 pandemic it can feel even more
difficult.

44. AFTER
 Do not light matcher or turn on lights or appliances
until you are sure there are no gas leaks or flammable
liquids spilled. Avoid use of contaminated water.
 Place help sign in your window if you need assistance.
 Experiencing a disaster is challenging enough, but

difficult.

45. NOW YOU KNOW!
 NOW YOU KNOW ABOUT HOW TSUNAMI
GERENERATED AND THE DIFFERENT SIGNS OF
THE IMPENDING TSUNAMI, HOW ARE YOU
GOING TO MITIGATE ITS EFFECT?

46. EVALUATION: TRUE OR FALSE
:
1. I should go to the shore to watch a tsunami
2. All undersea earthquakes cause tsunami.
3. If I felt a strong earthquake while near the coast, I
should wait to hear the rumbling sound before
moving to high ground.
4. If a small tsunami is coming, I should get out of the
water and wait until I hear it is safe to return.

47. EVALUATION: TRUE OR FALSE
5. If a big tsunami is coming, I should move as far inland
or to higher ground.
6. If I am swimming when a small tsunami comes, I could
get dragged out of the sea by the strong rips and
currents.
7. A tsunami is most often caused by undersea
earthquakes.

48. ASSIGNEMENT
Based on what you have learned so far, what are the areas
in your municipality or province that can possibly be
affected by tsunami.
 If my home is near the coast, will I be affected by
tsunami?
 How do I prepare for tsunami? (how far is your
home/school from the coast? To elevated area?
 Learner will write their answers on their journal.
