Typhoon Rammasun, a category 3 storm, threatened Manila on July 14, 2014, following the devastation of Super Typhoon Haiyan in 2013. Anticipatory actions led to the evacuation of at least 300,000 people, although many remained in their homes, while schools were closed and flights canceled. The document emphasizes the lessons learned from past typhoons, highlighting the importance of preparedness, timely evacuation, and wind-resistant building designs to mitigate future disasters.

1. 2014 TYPHOON SEASON
TYPHOON RAMMASUN
Tuesday, July 15, 2014

2. Rammasun is the strongest
storm to threaten the country
since Haiyan, a Cat-5 "super
typhoon," wiped out nearly
everything in its path when it
crossed over the central
Philippines in November, 2013.

3. RAMMASUN (CAT 3) WAS
HEADED FOR MANILLA—THE
FIRST DIRECT HIT ON THE
CAPITOL IN FOUR YEARS—
ON JULY 14, 2014

4. TYPHOON RAMMASUN HEADED
TOWARDS MANILLA

5. PHYSICAL DETAILS
• Typhoon Rammasun, with
gusts of up to 160 kph (99 mph)
and sustained winds of 130 kph
(81 mph) near its centre, hit
land over Rapu-Rapu island in
the eastern province of Albay,

6. TIMELY ANTICIPATORY
ACTIONS
• At least 300,000 people have
already fled from their homes
in Albay province alone.
• However, many people were
unwilling to evacuate.

7. TIMELY ANTICIPATORY
ACTIONS
• Schools were closed.
• International flights were
cancelled.
• The army was placed on high
alert.

14. REMEMBERING TYPHOON
HAIYAN

15. SUPER TYPHOON HAIYAN
DEVASTATED THE PHILIPPINES;
NOVEMBER 8-10, 2013

16. HAIYAN: A SUPER TYPHOON

17. HAIYAN REACHED THE
PHILIPPINES: FRIDAY, NOV. 8

18. LANDFALL ON FRIDAY
MORNING, NOV. 8

19. RATED AS PROBABLY THE
STRONGEST TYPHOON
EVER TO STRIKE THE
PHILIPPINES

20. ADVANCE EVACUATIONS
• 800,000 people were evacuated
to emergency shelters.

21. AN EVACUATION CENTER

22. INITIAL IMPACTS IN THE
PHILIPPINES
• Wide spread flooding,
mudslides, and power outages
• Winds of 380 kph (290 mph)
• TACLOBAN hit very hard by the
storm surge with many deaths
• Tacloban’s airport destroyed

23. TACLOBAN (ON LEYTE
ISLAND) HIT THE HARDEST

24. FOUR HOURS OF FEAR AND
DESTRUCTION
• Winds flattened hundreds of homes.
• Heavy rainfall triggered mudslides and
flash flooding.
• A storm surge with waves of up to 10 m
(30 feet) destroyed everything,
sweeping people away and drowning
thousands.

25. STORM SURGE

26. AN AERIAL VIEW
• It was like a tsunami," Interior
Secretary Manuel Roxas told
Reuters.
• "From a helicopter, you could see
the extent of devastation. From the
shore and moving a km inland, no
structures were left standing.

27. INITIAL IMPACTS IN THE
PHILIPPINES
• Loss of communication
• An estimated 10,000 people
dead
• Economic losses in the billions

28. SURVIVOR STORIES
• Survivors of the storm
described towering waves that
swept away all but the most
robust engineered structures.

29. DESTRUCTION EVERYWHERE

30. DESTRUCTION EVERYWHERE

31. DESTRUCTION EVERYWHERE

32. DESTRUCTION EVERYWHERE

33. DESTRUCTION AND DEATH
EVERYWHERE

34. DESTRUCTION EVERYWHERE

35. TACLOBAN AIRPORT

36. SURVIVOR NEEDS
• Survivors were in desperate need
of clean drinking water and food
• Survivors were temporarily cut off
from aid, and from their families in
the Philippines as well as in other
countries (e.g., 3 million in the
USA)

37. USA MILITARY FORCES
WERE DISPATCHED TO
ASSIST LOCAL OFFICIALS
IN WHAT BECAME A
HISTORIC RELIEF EFFORT

38. Search and Rescue and Relief
Efforts Were Hampered by
Landslides and Damaged Road
Systems

39. LOOKING TO THE FUTURE

40. ONCE AGAIN, TYPHOON HAIYAN
DEMONSTRATED THAT IT
USUALLY TAKES MULTIPLE
DISASTERS BEFORE THE
STRICKEN NATION WILL ADOPT
POLICIES TO BECOME DISASTER
RESILIENT

41. ONCE AGAIN, UNAFFECTED
NATIONS USUALLY DON’T
LEARN ANYTHING NEW AND
DON’T CHANGE EXISTING
POLICIES ON THE BASIS OF
ANOTHER NATION’S
EXPERIENCES

42. TYPHOON DISASTER RESILIENCE
POLICIES AND MEASURES ARE
NEEDED BY MANY NATIONS
Preparedness
Adoption and Implementation of a Modern Wind
Engineering Building Code
Time,y Early Warning and Evacuation
Timely Emergency Response (including
Emergency Medical Services)
Cost-Effective Recovery

43. BASES FOR POLICIES THAT CALL FOR
TYPHOON DISASTER RESILIENCE
EXPERIENCES WITH
PREPAREDNESS
EXPERIENCES WITH
MONITORING AND WARNING
EXPERIENCES WITH
DISASTER SCENARIO
PLANNING
EXPERIENCES WITH
RECOVERY AND
RECONSTRUCTION
EXPERIENCES WITH
PREVENTION, MITIGATION,
AND ADAPTATION
INTEGRATE GLOBAL
EXPERIENCES WITH
LOCAL EXPERIENCES

44. THE CHALLENGE:
POLICY CHANGES: CREATE, ADJUST, AND
REALIGN PROGRAMS, PARTNERS AND
PEOPLE UNTIL YOU HAVE CREATED THE
KINDS OF TURNING POINTS NEEDED FOR
MOVING TOWARDS TYPHOON RESILIENCE

45. LESSON: ANTICIPATORY ACTIONS
ARE THE KEY TO PREPAREDNESS
• The people who know: 1) what to
expect (e.g., high-velocity winds,
rain, flash floods, landslides, and
storm surge), 2) where and when it
will happen, and 3) what they
should (and should not) do to
prepare will survive.

46. LESSON: EMERGENCY
RESPONSE IS COMPLEX
• All kinds of things can go
wrong during the emergency
response period when the
uncontrollable and unthinkable
events happen along with the
expected events

47. LESSON: TIMING OF EMERGENCY
RESPONSE IS VITAL
• The “Uncontrollable and
Unthinkable” events can
significantly hinder the timing of
urgent emergency response
operations.

48. LESSON: TIMELY EARLY WARNING
AND EVACUATION SAVES LIVES
• The people who have timely early
warning in conjunction with a
community evacuation plan that
facilitates getting out of harm’s way
from the risks associated with
storm surge, high winds, flooding,
and landslides will survive.

49. LESSON: WIND ENGINEERED
BUILDINGS SAVE LIVES
• Buildings protected by wind
engineering to withstand a
typhoon’s high velocity winds will
maintain their function, protect
occupants and users, and minimize
death and injury.

50. LESSON: EMERGENCY MEDICAL
PREPAREDNESS SAVES LIVES
• Damaged hospitals and medical
facilities combined with lack of
clean drinking water, food, and
medicine, and high levels of
morbidity and mortality will quickly
overrun the local community’s
capacity for emergency health care.

51. LESSON: THE INTERNATIONAL
COMMUNITY PROVIDES AID
• The International Community
provides millions to billions of
dollars in relief to help “pick up the
pieces, ” but this strategy by itself is
not enough to ensure typhoon
disaster resilience.

52. CREATING TURNING POINTS FOR
TYPHOON DISASTER
RESILIENCE
 USING EDUCATIONAL SURGES CONTAINING
THE PAST AND PRESENT LESSONS TO FOSTER
AND ACCELERATE THE CREATION OF TURNING
POINTS

53. THE PEOPLE OF THE PHILIPPINES
HAVE HAD MANY
OPPORTUNITIES TO LEARN
VITAL LESSONS
FROM PAST TYPHOONS OF ALL
SIZES MAKING LANDFALL THERE
The Philippines has more than enough
experience with typhoons for action.
