EARTHQUAKE
HAZARDS
WHAT IS AN EARTHQUAKE?
“The perceptible shaking of the surface
of the Earth, resulting from sudden
release of energy in the Earth’s crust
that creates seismic waves.”
(United States Geological Science-USGS)
LET US RECALL!
• Fault or fault plane- where the ground split
• Hypocenter- where earthquake originates
• Epicenter- where it occurs at the earth
surface
• Convergent Boundary- when one plate is
force over another during an earthquake
• Divergent Boundary- when plates drifted
apart from each other
• Transform Fault- when plates slip by each
other.
LET US RECALL!
• Intensity- earthquake’s property that
indicates the effects and damage caused by
• batay sa sa naramdaman ng mga tao at sa
epekto sa kapaligiran at mga gawang
(Intensity I-X)
LET US RECALL!
• Magnitude- a value that tells the
reader the amount of seismic energy
released by an earthquake.
• impormasyon mula sa instrument
gaano kalakas ang enerhiya na inilabas
lindol (M= 7.2)
EARTHQUAKE HAZARDS
 Ground shaking or Ground motion
 Ground Surface Rupture
 Liquefaction
Tsunami
 Earth-quake induced Landslide
Measured in
the:
1. Velocity of
ground motion
2. Acceleration
of ground
motion
3. Frequency
content of the
shaking
4. Duration

WHEN WILL THE “BIG ONE” HAPPEN?
No one knows!
What science knows is, the return period of
earthquake is about 200 - 400 years and
large earthquake has happened in the West
Fault since the 1700s. The last was in 1658
years ago)

TSUNAMI
“Harbor

or
“Seismic Sea

Signs of an Impending TSUNAMI
1. ANIMAL BEHAVIOR
Zoologist hypothesize that some animal
species like elephants have the ability to
sense subsonic Rayleigh waves from an
earthquake or a tsunami.

LUMIKAS
Dapat agarang lumikas ang mga komunidad
na nasa baybaying-dagat patungo sa mas
mataas na lugar o papalayo sa baybaying-

MAGMATYAG
Pinapayuhan ang publiko na maging alerto sa
mga di-pangkaraniwang alon sa karagatan;
lumayo sa baybaying-dagat at huwag
magtungo sa dalampasigan para panoorin

• Do not use your telephone to call relatives and
friends. Disaster prevention authorities may
need the lines for emergency communications.
• Do not use your car and drive around disaster-
striken areas. Rescue and relief operations
need the roads for mobility.
• Check your water and electrical lines for
defects. If any damage is suspected, turn the
system off in the main valve or switch.
TRAPPED?
• Pray
• Check pockets or bags for lighter – anything that will help
you scratch, dig, screw or signal way out.
• Make noise (bang pipes, car horn, whistle, etc.)
• Conserve energy
• Do not drink urine or alcohol (man can survive 10 days
without food; 3 days without water; no one drinks on the
first day)
• Mobile phones: text instead of calling, or be concise if

Editor's Notes

  1. Quake, tremor, or temblor
  2. Quake, tremor, or temblor
  3. Intensity- it can be determined by taking the stock of devastation in the area affected. (Mercalli Scale; Giuseppe Mercalli 1902)
  4. Magnitude- calculated by measuring the amplitude of the seismic waves through a seismometer.
  5. The Earth shakes with the passage of earthquake waves, which radiate energy that had been “stored” in stressed rocks, and were released when a fault broke and the rocks slipped to relieve the pent-up stress. Ground shaking will vary over topography, bedrock type, and the location and orientation of the fault rupture.
  6. The entire City of Bacoor is susceptible to experience up to Intensity 8 of ground shaking should there be any movement in the nearby West Valley Fault Line that generates a Magnitude 7 earthquake with a depth of 10kms.
  7. Any structure built across the fault is at risk of being torn apart as the two sides of the fault slip past each other. Dip-slip faulting (vertical offset) Strike-slip faulting (lateral offsets)
  8. Phenomenon in which the strength and stiffness of a soil is reduced by earthquake or other rapid loading. It normally occurs in saturated soil (in which the space between individual particles is completely filled with water). Liquefied soil will force open ground cracks in order to escape to the surface. Ito ay naoobserbahan lamang sa mga lugar na binubuo ng sediments (putik, buhangin) o lupa na nakababad sa tubig Ang sediments o lupa sa ilalim ng water table ay pansamantalang nawawalan ng tibay
