100
What is a Body Wave?
A wave that move through the inside of the earth.
100
What is triangulation?
The process of locating the center of an earthquake through the use of 3 different stations.
100
What is a normal fault?
A fault type in which the two plates move away from each other.
100
What is a tsunami?
A natural disaster that can result from an earthquake causing the vertical movement of the sea floor.
100
What is the richter scale?
A logarithmic scale for earthquakes based on the magnitude of the wave.
200
What is a Primary Wave?
The fastest type of body waves, that push and pull rocks in the direction of the wave.
200
What is an epicenter?
The center of an earthquake on the surface.
200
What is a reverse fault?
A type of fault that occurs on a convergent boundary.
200
What is 5-15 floors?
The range of floors that a building could have that would most likely result in a collapse from an earthquake?
200
What is compression?
Type of stress associated with reverse faults.
300
What is a Secondary Wave?
A body wave that can only pass through solids, and moves rock perpendicular to the wave.
300
What is a seismograph?
The device used to observe in progress earthquakes.
300
What is a hanging wall?
The block of rock positioned above the fault, in a hanging shape.
300
What are unreinforced buildings?

or

What are buildings made of brittle material? (ex: stone/concrete)
Building types that result in the greatest damage in earthquakes.
300
What is tension?
Type of stress associated with normal faults.
400
What is a Love Wave?
A surface wave that moves the ground side to side.
400
What is a seismogram?
The output of a device observing in progress earthquakes.
400
What is a strike-slip fault?
A type of fault in which the two sections move adjacent to each other.
400
What are wooden buildings?

or

What are high-rise, steel framed buildings?
Types of buildings that result in the least damage from earthquakes.
400
What is the mercalli scale?
A scale for earthquakes based on damage.
500
What is a Rayleigh Wave?
A wave that rolls along the surface of the ground in a circular movement.
500
What is a travel-time graph?
A graph that is used to calculate distance to epicenter of an earthquake, based on arrival times of both wave types.
500
What is a foot wall?
The block of rock positioned on the underside of the fault.
500
What is soil liquefaction?
The liquefying of subsurface materials.
500
What is horizontal shear?
Type of stress associated with strike-slip faults.
