it is the shaking and trembling of the Earth’s surface caused by a sudden release of energy in the Earth’s crust.
Earthquake
These faults are still moving and can cause earthquakes in the future, What is it?
active fault
These faults haven’t moved in a long time and are less likely to cause earthquakes.
Inactive fault
A type of fault which Happens when rocks are pushed together and one block moves up over the other.
Reverse fault
Occurs when rocks slide horizontally past each other.
strike-slip fault
Occurs when rocks are pulled apart and one lock moves down relative to the other.
normal fault
Is the type of stress that causes the rocks to push or squeeze against one another.
compression stress
when two plates rub against each other as they move in opposite direction.
shear stress
Is the two separate plates can move farther away from each other, or the end of one plate can move in different directions.
tension stress
the origin or the center of the earthquake and is located underground.
focus
A point of the surface of the earthquake which is directly above of the focus of an earthquake and where the earthquake vibration reach first.
epicenter
lateral waves that move side to side as a sine wave perpendicular to the direction of the wave.
S-wave
a type of surface wave producing both a vertical and horizontal component of motion in the direction of wave propagation, that travel near the surface of solids.
Rayleigh wave
a type of surface wave having a horizontal motion that is shear or transverse to the direction of propagation, that travel near the surface of solids.
love wave
it is an instrument that responds to ground displacement and shaking such as caused by quakes, volcanic eruptions, and explosions.
