Earthquake Waves | Epicenter Triangulation | Fault Types | Earthquake Hazards | Stress/Measurement |
---|---|---|---|---|
What is a Body Wave?
A wave that move through the inside of the earth.
|
What is triangulation?
The process of locating the center of an earthquake through the use of 3 different stations.
|
What is a normal fault?
A fault type in which the two plates move away from each other.
|
What is a tsunami?
A natural disaster that can result from an earthquake causing the vertical movement of the sea floor.
|
What is the richter scale?
A logarithmic scale for earthquakes based on the magnitude of the wave.
|
What is a Primary Wave?
The fastest type of body waves, that push and pull rocks in the direction of the wave.
|
What is an epicenter?
The center of an earthquake on the surface.
|
What is a reverse fault?
A type of fault that occurs on a convergent boundary.
|
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?
|
What is compression?
Type of stress associated with reverse faults.
|
What is a Secondary Wave?
A body wave that can only pass through solids, and moves rock perpendicular to the wave.
|
What is a seismograph?
The device used to observe in progress earthquakes.
|
What is a hanging wall?
The block of rock positioned above the fault, in a hanging shape.
|
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.
|
What is tension?
Type of stress associated with normal faults.
|
What is a Love Wave?
A surface wave that moves the ground side to side.
|
What is a seismogram?
The output of a device observing in progress earthquakes.
|
What is a strike-slip fault?
A type of fault in which the two sections move adjacent to each other.
|
What are wooden buildings?
or What are high-rise, steel framed buildings?
Types of buildings that result in the least damage from earthquakes.
|
What is the mercalli scale?
A scale for earthquakes based on damage.
|
What is a Rayleigh Wave?
A wave that rolls along the surface of the ground in a circular movement.
|
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.
|
What is a foot wall?
The block of rock positioned on the underside of the fault.
|
What is soil liquefaction?
The liquefying of subsurface materials.
|
What is horizontal shear?
Type of stress associated with strike-slip faults.
