chapter 5 earthquake notes

stress a force that acts on an area of rock to change its shape or volume
tension streches rock and pulls on the crust.
compression pushes rock together
shearing can cause masses of rock to slip
normal faults has tension in Earths crust pulls rock apart
hanging wall the block of rock that lies abouve
footwall a rock that lies below
reverse fault has the same strucsure as a normal fault,but the blocks move in the opposite direction
strike-slip fault the rocks on either side of the fault slip past eachother sideways with little up or down motion
surface waves move more slowley than P waves and S waves
P waves when the crust vibrates forward and back along the path of the wave
S waves when the crust vibrates from side to side and up and down
mercalli scale was devoloped to rate earthquakes according to their intetensity or strength at a place
magnitude a number that geologist assign to an earthquake based on the its size
ritcher scale assigns a magnitude number to an earthquake based on the seismic wave size
siesmograoh an instroment that recordes and measures siesmic waves
moment magnitude scale a rating system that estimates the total energy realeased by an earthquake
earthquake the shaking that results from the sudden movment of rock along a fault
focus the area beneath earths surface where rock that is under stress breaks making an earthquake.
epicenter the focus directly above the point on the surface.
