Accepted Answer

A)  Fires 
B)  Elevation changes 
C)  Tsunami 
D)  Liquefaction 
E)  Ground rupture

Question 2

Strong earthquakes have been felt in Southeast Missouri, what causes these earthquakes?

Accepted Answer

A)  Dip-slip faults from subduction 
B)  Strike-slip faults from a transform plate boundary 
C)  megathrust earthquakes from a divergent plate boundary 
D)  megathrust earthquakes from a convergent plate boundary 
E)  These are intraplate earthquakes.

Question 3

Which of the following statements is FALSE about P-waves?

Accepted Answer

A)  P-waves are the fastest of the waves. 
B)  P-waves can move through solid, liquids, or gases. 
C)  P-waves are a type of compressional wave that moves with a push/pull motion. 
D)  P-waves cause the most damage in an earthquake.

Question 4

During an earthquake will one side of the fault always rise up relative to the other side?

Accepted Answer

A)  Yes. Earthquakes are always associated with upward movement along the fault. 
B)  Yes. Earthquakes are always associated with subduction. 
C)  No. Faults in earthquakes never move up and down. 
D)  No. Faults in earthquakes sometimes are preceded by ground uplift, but not always. 
E)  No. Faults that rise up are usually associated with volcanoes and not earthquakes.

Question 5

Blind faults are dangerous because they do not always extend to the surface and thus could be undetected.

Accepted Answer

A) True 
 B)False

Question 8

Mexico City was built on mud deposits. How will this affect the earthquake hazard there?

Accepted Answer

A)  Earthquakes will be dampened there. 
B)  There will not be any earthquakes there. 
C)  Earthquakes shaking will be increased. 
D)  The ground will be susceptible to supershear, which will cause sonic booms that increase damage. 
E)  There will be more earthquakes due to brittle rupture of the mud.

Question 9

The probability of a major flood in any given year is the same whereas the probability of a major earthquake in any given year changes over time. Explain both how and why the probability of a major earthquake changes over time.

Accepted Answer

D)  Fault that is creeping slowly 
E)  Fault that is not moving

Question 13

Seismic gap refers to a region where no seismic activity ever occurs.

Accepted Answer

A) True 
 B)False

Question 14

What is the difference between earthquake intensity and magnitude?

Accepted Answer

A)  Only strong earthquakes have intensity; weak earthquakes have magnitude and intensity. 
B)  Intensity refers to the effects that earthquakes have, magnitude refers to energy released. 
C)  Intensity refers to energy released and magnitude refers to the effects that earthquakes have. 
D)  Only weak earthquakes have intensity; strong earthquakes have magnitude and intensity.
