---|---|---|---|
What is a fault?
This is a fracture surface along which rocks can slip
|
What is a P wave?
The type of seismic wave that travels the fastest.
|
What is a seismograph?
This instrument helps to measure the magnitude of an earthquake.
|
What is fires caused by ruptured gas or electrical lines?
The most common hazard following an earthquake.
|
What is elastic strain?
This is the direct cause of earthquakes
|
What is secondary waves?
This type of seismic wave can travel through solids but NOT through liquids.
|
What is a seismograph?
This instrument records seismic waves.
|
What is a tsunami?
Another name for a seismic sea wave.
|
What is a strike-slip fault?
The fault type that is assocaited with transform plate motion and moderate, shallow earthquakes
|
What is P waves?
The following statement is true of what type of seismic wave:
"They travel fastest through rock" |
What is the P-waves?
This type of seismic wave shows up first on a seismograph.
|
What is liquefaction?
The type of hazard when a building is sitting on loose or unstable ground and an earthquake causes that dirt to move like liquid.
|
What is convergent?
The plate motion associated with a reverse fault and STRONG, DEEP earthquakes
|
What is a surface wave?
This type of seismic wave causes the most damage.
|
What is three?
The amount of seismograph recordings needed to locate the epicenter of an earthquake.
|
What is fault lines?
People living along this are at the greatest risk from the effects of earthquakes.
|
What are weak and shallow?
The characteristics associated with earthquakes that come from divergent plate motion and a normal fault line
|
What are P and S waves?
These types of waves help scientists to determine the internal structure of the earth.
|
What is the Moment Magnitude Scale?
The amount of energy released during an earthquake is measured on this type of scale.
|
What is BEING PREPARED!
The best defense against an earthquake
