Earthquakes
- The Philippines is located in
the Ring of Fire.
- The Ring of Fire is a ring of volcanoes around the Pacific Ocean
that result from subduction of oceanic plates beneath lighter
continental plates.
- Most of the Earth’s volcanoes are located around the Pacific Ring
of Fire because that’s the location of most of the Earth’s
subduction.

- The Ring of Fire is a ring of volcanoes around the Pacific Ocean
that result from subduction of oceanic plates beneath lighter
continental plates.
- The Philippines is located along a
convergent boundary.
- Along the boundaries, rocks bend
or break.
- Breaks in rocks are called fractures.
(fracture, fault, or joint)
- Faults are breaks along rocks
with movement.
- Rocks get squeezed and/or
stretched.
- When they do, they
STORE ENERGY.
- When they can't anymore, they
BREAK and RELEASE THE STORED
ENERGY.

- A Seismograph
measures and
records seismic
waves made by an
earthquake.
- The amplitude of shaking recorded by the
seismograph is converted to Richter scale
magnitude, which uses a scale in the
powers of ten scale.

- Earthquakes generate waves
that travel through the earth
- Earthquakes occur when rocks slip along faults
- Faults are classified by the kinds of movement that occur
along them

- Faults are classified by the kinds of movement that occur

- Earthquakes occur when rocks slip along faults
- Epicenter: The point at the surface of the Earth above the
focus
- Focus (Hypocenter): The point within the Earth where an
earthquake rupture starts
- Focus (Hypocenter): The point within the Earth where an
earthquake rupture starts
- Where is this energy released?
- Energy is released in the form of seismic waves.
- Energy is released in the form of seismic waves.
- Intensity:
effect of an
earthquake
and how it is
felt by people.
tells us how
much a certain
area was
shaken when
the
earthquake
reached that
area,
- Magnitude:
describes the total
amount of energy
that was released by
the earthquake at
the focus. -
determined from
seismic records
- The effects of an earthquake can be very different from place
to place . An earthquake can have many different intensity
numbers although it only has one magnitude.
- The primary effects of earthquakes are ground shaking, ground
rupture, landslides, tsunamis, and liquefaction. Fires are
probably the single most important secondary effect of
earthquakes.

- The resulting
magnitudes reflect
a10 times increase in
strength for every
increase of one in the
Richter magnitude
