• The shaking of the Earth’s surface resulting from the sudden release of energy in the lithosphere is referred to as an earthquake.
• The stress along the outer layer of the Earth causes the build-up of energy.
• Normal faults are illustrated by a hanging wall slipping down the footwall.
• A fracture between two blocks of rocks is referred to as a fault.
• Earthquakes occur frequently in Japan, Indonesia, and Philippines due to their location within the Pacific Ring of Fire.
• In a fault slip, the rocks either stick together, slide past each other, or there is no movement at all.
• The Rocky Mountains were formed by a normal fault.
• The San Andreas fault is a strike-slip fault.
• A transform fault shows two plates moving apart from each other.
• A factor that keeps the rocks from slipping past each other is their arrangement, bending, depth, or roughness.
• Rocks cannot release this energy due to friction, bending, vibration, or depth.
• A reverse fault forms when the hanging wall moves downward relative to the footwall.
• A thrust fault is described by two blocks of crust pushing together.
• The illustrators of the module are Angelo Zaldy C. Francia, Victor Genesis O. Odtohan.
• There are three kinds of faults: strike-slip, normal, and thrust (reverse) faults.
• Earthquakes are the shaking of the surface of the Earth resulting from the sudden release of energy in the Earth’s lithosphere.
• The energy will eventually be released once the fault overcomes the friction movement.
• Earthquakes cannot be stopped from happening, but there are things that people can do to avoid or decrease the loss of life and damage to property.
• Seismologists are still figuring out how to detect seismic tremors accurately.
• People who live along the Ring of Fire must anticipate the occurrence of earthquakes and volcanic eruptions.
• Strong earthquakes have caused countless deaths all over the world, even before people have started recording these events.
• The Philippines can be located on the globe by determining its latitude and longitude or by identifying the landmasses and bodies of water in the surrounding area.
• The grinding over the surface of the fault holds the rocks together so they do not slip promptly when pushed sideways.
• Earthquakes are generated by the movement of faults.
• Faults are thin zones of crushed blocks of rocks that can be hundreds of centimeters to thousands of kilometers long.
• The surfaces of faults can be vertical or horizontal and they can expand into the earth and might possibly reach out up to the Earth's surface.
• Faults are also breaking in the Earth's crust where rocks on either side of the crack have slid past each other.
• Stress in the outer layer of the Earth pushes the sides of the fault together.
• An earthquake is brought about by an abrupt slip on a fault, much like what happens when you snap your fingers.
• Examples of strike-slip faults are the San Andreas Fault and the Anatolian Fault.
• Strike-slip faults are rocks sliding past one another on a horizontal plane, with little to no vertical movement.
• The amount of ground displacement in an earthquake is called the slip.
• Faults are compressional, pushing the sides together.
• When rocks slip past each other in faulting, the upper or overlying block along the fault plane is known as the hanging wall, or headwall and the lower block is known as the footwall.
• Faults are pulling the sides apart.
• Transform faults have walls that move sideways, not up or down.
• Normal faults form when the hanging wall drops down.
• Reverse faults, also known as thrust faults, are rocks sliding one block of crust on top of another.
• Normal faults are two blocks of crust layer pulling apart, extending the crust into a valley thus, creating a space.
• Reverse faults form when the hanging wall moves up.
