This type of wave moves rock up and down like a wave in a rope.
What is an S wave.
100
Type of fault caused by compression.
What is reverse fault?
100
Earthquakes usually occur at faults along here.
What is a plate boundary?
100
Stress as this to rocks.
What is energy?
200
Place inside the Earth where the earthquake starts
What is the focus?
200
These waves are the slowest waves, but are the most devastating to buildings.
What are surface waves?
(P waves are the fastest.)
200
This scale measures the amount of damage or intensity and earthquake produces.
What is Mercalli Scale?
200
This type of stress causes a normal fault.
What is tension?
200
The highest risk of earthquakes in the USA occurs in this REGION?
What is the Pacific Coast?
300
Stress that pushes rock in opposite directions.
What is shearing?
300
Seismograph data tell you what about the epicenter of an earthquake?
What is how far away the epicenter is?
(You need three seismographs to pinpoint EXACTLY where the epicenter is located.)
300
With this type of fault, the two sides of the fault move past each other in opposite directions.
What is a strike - slip fault?
300
A creep meter uses a wire stretched across to sides of a fault to measure this type of movement.
What is movement in opposite directions?
400
Stress that causes folding?
What is compression?
400
These waves move like an accordion and can move through solids and liquids.
What are P waves.
400
The Richter Scale assigns this to an earthquake to measure the size of seismic waves.
What is a magnitude number?
400
In a normal fault, the hanging wall does this in relation to a footwall?
What is move down in relation to the footwall?
400
These four things can cause damage during an earthquake.
What are shaking, liquefaction, aftershocks, and tsunamis?
500
A fold in the crust that bends UPWARD into an arch.
What is an anticline?
(A syncline is when the rock bends down.)
500
To tell HOW FAR a seismograph is from the epicenter, geologists do this.
What is measure the difference in time between the P and S waves.
(To tell the EXACT LOCATION of an epicenter, geologists need the data from three different seismographs.)
500
A creep meter and a laser ranging device measure this tpe of movement.
What is horizontal movement?
500
In a reverse fault, the hanging wall does this in relation to the footwall.
What is move up?
500
Forces of plate movement, can produce these five landforms.
What are anticlines, synclines, fault block mountains, folded mountains, and plateaus.
