MALAYSIA: KUALA LUMPUR
IS THE FEDERAL CAPITAL
MALAYSIA
•

•
Population: 23,522,482
Area: 329,750 km2
Coastline: 4675 km
GDP: $207.8 billion
GDP Per Capita: $9,000
MALAYSIA IS AT RISK FROM
EARTHQUAKES & VOLCANOES
• EARTHQUAKES
and VOLCANIC
ERUPTIONS
(usually from
sources outside
the country; i.e.,
Indonesia, not
inside)
WESTERN MALAYSIA,
WHERE KUALA LAMPUR IS
LOCATED, IS AT GREATER
RISK FROM NATURAL
HAZARDS THAN EASTERN
MALAYSIA
KUALA LUMPUR
KUALA LUMPUR
• The city covers an area of 243 km2
(94 sq mi) and had an estimated
population of 1.6 million in 2010.
• Greater Kuala Lumpur, also known as
the Klang Valley, was an urban
agglomeration of 6.9 million in 2010
and one of the fastest growing
metropolitan regions in Malaysia.
MALAYSIA: PART OF THE COMPLEX
EURASIAN AND INDO-AUSTRALIAN
PLATE TECTONICS
MALAYASIA IS ON THE
SUNDA SUB-PLATE
THE SUNDA TECTONIC
PLATE
• The Sunda Plate is a minor tectonic
plate on which the majority of
Southeast Asia is located.
• The Sunda Plate was formerly
considered a part of the Eurasian plate,
but GPS measurements have
confirmed its independent movement at
10 mm/yr eastward relative to Eurasia.
EARTHQUAKE OF
JUNE 5, 2015
M6.0 (USGS)
16 km northwest of Ranau, Sebah
DEPTH: 54 km (34 mi)
Sabah Deputy Chief Minister Joseph
Pairin Kitingan blamed the tragedy on
a group of 10 foreigners who
"showed disrespect to the sacred
mountain" by posing naked at the
peak last week.
He said a special ritual would be
conducted later to "appease the
mountain spirit."
PHYSICAL EFFECTS
• The M6.0 earthquake struck early
Friday near Malaysia’s Mount
Kinabalu a popular tourist
destination.
• The ground shaking triggered
landslides, sending huge granite
boulders tumbling down the 4,095meter-high peak.

PRELIMINARY SOCIAL
EFFECTS
• By Saturday, the death toll had
reached 13.
• Some climbers were stranded;
others made it down safely.
• People were advised to expect
aftershocks
PRELIMINARY SOCIAL
EFFECTS
• The ground shaking damaged
buildings, schools, a hospital, and
roads in Ranau.
SEARCH AND RESCUE
OPERATIONS
• About 60 rescuers and four
helicopters were combing the
mountain, where loose rocks and
boulders that fell during the quake
blocked part of the main route.
SEARCH AND RESCUE
MALAYSIA IS AT RISK FROM OTHER
NATURAL HAZARDS
• CYCLONES
• FLOODS
(especially during
cyclone season)
• LANDSLIDES
(TRIGGERED BY
TOO MUCH RAIN OR
EARTHQUAKE
GROUND SHAKING )
Floods and landslides from
cyclones are the primary hazards
affecting Malaysia.
Effects from earthquakes and
volcanic eruptions are usually
from distant sources.
Droughts also occur.
KUALA LUMPUR AND
PUTRAJAVA
• Kuala Lumpur is the cultural, financial,
and economic center of Malaysia, and
also the seat of Malaysia’s Parliament
and the official residence of the King.
• Putrajava is the location of the
executive and judicial branches of the
federal government, which were
relocated from Kuala Lumpur in 1999.
TOWARDS DISASTER RESILIENCE
IN MALAYSIA
A Paradigm Shift
From Disaster Proneness Will Improve
the Quality of Life in Malaysia
CONTINUATION OF THE STATUS
QUO WHEN MALAYSIA IS AT RISK
AND DISASTER PRONE - - Will result in new and more complex
HEALTH PROBLEMS
WILL result in unnecessary
DEATHS AND INJURIES
WILL result in longer and more costly
RECOVERY and RECONSTRUCTION
A PARADIGM SHIFT TOWARDS
DISASTER RESILIENCE IN
MALAYSIA - - Will result in fewer and less complex
HEALTH PROBLEMS
WILL result in fewer
DEATHS AND INJURIES
WILL result in shorter and less costly
RECOVERY and RECONSTRUCTION
A PARADIGM SHIFT FROM
DISASTER PRONENESS
TOWARDS DISASTER
RESILIENCE IS
A THREE STEP PROCESS
TOWARDS DISASTER RESILIENCE
IN MALAYSIA
• Step 1: Integrate Past Experiences Into
Books of Knowledge
• Step 2: From Books of Knowledge to
Innovative Educational Surges to Build
Professional and Technical Capacity
• Step 3: From Professional and Technical
Capacity to National Disaster Resilience
Step 1: Integrate Past
Experiences Into Books of
Knowledge
NOTE: A book of Knowledge is
everything we know or think we know
about Malaysia’s risk-causing
hazards
BOOKS OF KNOWLEDGE
Are “TOOLS” to facilitate a
commitment by Malaysia to minimize
the likely impacts of the inevitable
future cyclones, floods, landslides
earthquakes, volcanic eruptions, and
droughts, thereby anticipating and
preventing disasters
WHAT DO WE KNOW?
• Disaster resilience has become an
urgent global goal in the 21st
century as many Nations are
experiencing disasters after a
natural hazard strikes, and learning
that their communities, institutions,
and people do NOT yet have the
capacity to be disaster resilient.
Step 2: From Books of
Knowledge to Innovative
Educational Surges to Build
Professional and Technical
Capacity in Malaysia to
Minimize Likely Impacts in the
Next Disaster
NOTE: Step 2 is a task for a
Nation’s “Academies of Science,
Engineering and Medicine,” its
educational institutions at all
levels, and its electronic and
print media that provide public
information
WHAT DO WE KNOW?
• Disaster resilience does not just
happen; it is the result of decisionmaking for a national paradigm shift
from the status quo to an improved
“coping capacity” that enables the
country to recover quickly after a
disaster.
GOAL: MINIMIZE THE “DOMINO
EFECTS” OF THE NEXT DISASTER
Step 3: From Professional and
Technical Capacity to Sciencebased Decision-making for a
Paradigm Shift from the status
quo to Disaster Resilience in
India
NOTE: Step 3 is a task for
Malaysia’s “decision-makers,”
(i.e., its political leaders,
stakeholders, and leading
professionals)
who have a basis for deciding
on the nature and scope of a
national paradigm shift
