Objective
• Explain how movements along faults
generate earthquakes.
Some of the countries located in the Pacific Ring of Fire include the Philippines,
Japan, Taiwan, New Zealand, Russia, Antarctica, Indonesia, Canada,
Mexico, Chile, United States, Peru, Canada and Papa New Guinea.
An earthquake is the sudden shaking of the ground which lasts for seconds. It
causes destruction anywhere it occurs, and no one knows exactly when and
where it is going to happen. Sometimes, it could lead to a tsunami, or a large
ocean wave created by undersea earthquakes or volcanic eruptions. An
earthquake wave is also known as seismic wave.

July 16, 1990
• Faults are fractures in the Earth’s crust
where rocks on either side of the crack have
slid past each other. Just like in
the experiment, a break was formed in the
clay, which represents the soil, as movement
occurs and the parallel lines are displaced.
Layers of rocks may experience several types of stress.
Stress is a force that acts on rocks to change its shape
or volume.
Tension is a type of stress that pulls on the
crust stretching the rock from opposite directions.
Compression is a force that squeezes rocks until they
fold or break.
Shearing is a force that pushes masses of rock in
different directions.
•
Strike-Slip Faults
• are rocks sliding past one another on a horizontal plane, with little to no vertical
movement. Examples to these are the San Andreas Fault and the Anatolian Fault
Normal Faults
• are two blocks of crust layer pulling apart, extending the crust into a valley thus, creating a space. A
normal fault has the upper side or hanging wall appears to have moved downward with respect to the
footwall. The Basin and Range Province in North America and the East African Rift Zone are two
notable districts where normal fault is spreading apart Earth's crust
Reverse Fault
• are also known as thrust faults, the slide one block of crust on top of another.
These faults are normally found in collision zones where tectonic plates push up
mountain ranges, for example, the Himalayas and Rocky Mountains.
