Science 8

1. Prepare the
following:
 Folder
 Fault Model
 Scissors
 Glue
 Ruler
 Colored Paper
(Green, Brown,
and Blue) or
Colors

5.  Epicenter
• Point directly above the focus
 Hypocenter
• The source from which the
energy is released radiating
from all directions.

7.  Fault Plane
• The surface along which the plate
breaks and slides
 Fault Zone
• The region with prominent but less
dense fractures and deformations
that mark the end of the fault plane

8. The large fractures in rocks formed
by shifting or dislodging of parts of
the Earth’s crust, often when
adjacent surfaces moved with
respect to each other.

9. Two types according to
displacement of the plates
Three types according to
geometry and orientation

10.  Where earthquakes are most
likely to happen in the future.
 There are recorded seismic
activities in the last 10,000 years

11. Marikina Valley Fault:
 Montalban
 San Mateo
 Marikina
 Pasig
 Taguig
 Muntinlupa
 San Pedro
 Biñan
 Carmona
 Santa Rosa
 Calamba
 Tagaytay
 Oriental Mindoro

12. Western Philippine
Fault:
 Luzon Sea
 Mindoro Strait
 Panay Gulf
 Sulu Sea
Eastern Philippine Fault:
 Philippine Sea
Southern of Mindanao
Fault:
 Moro Gulf
 Celebes Sea

13. Central Philippine Fault:
 Entire Ilocos Norte
 Aurora
 Quezon
 Masbate
 Eastern Leyte
 Southern Leyte
 Agusan Del Norte
 Agusan Del Sur
 Davao del Norte

14.  There are no seismic activities
in the last 10,000 years
 May possibly generate an
earthquake in the future

16.  Dip-Slip Fault (Normal and Reverse)
 Strike-Slip Fault (Left-lateral and Right-lateral)
 Oblique-Slip Fault

17. Hanging wall movement
determines the geometric
classification of faulting

18. The hanging wall moved
predominantly up or down relative
to the footwall
• Normal Fault
• Reverse Fault

19.  The hanging wall
slips down relative
to the footwall
 Happens at
divergent
boundaries

20. The hanging wall
slides over the
footwall.
Happens at
convergent
boundaries

21. The motion of
plates are
horizontal

22.  If the hanging wall moves
to the left, the
earthquake is called
right-lateral strike-slip
fault
 If it moves to the right,
it's called a left-lateral
strike-slip fault

24. The hanging wall motion
is neither dominantly
vertical nor horizontal,
the motion is called
oblique-slip.

26. An instrument used to detect and
record seismic waves

27. SEISMOGRAPH

28. Seismogram is a record written by a seismograph in
response to ground motions produced by an earthquake
