ANSWER ALL QUESTIONS IN THIS SECTION
QUESTION 1
Divergent Boundary Seismicity - ANSWERS-Earthquakes that occur at mid-ocean
ridges at shallow depths, have two kinds of faults responsible for tremors:
- Strike-slip
- Normal
QUESTION 2
Transform Boundary Seismicity - ANSWERS-Earthquakes that occur along
transform boundaries.
QUESTION 3
Convergent Boundary Seismicity - ANSWERS-Earthquakes can occur at shallow,
intermediate, or deep depths.
Possibly a result from the phase change of olivine to spinel (a denser material).

QUESTION 4
Intraplate Seismicity - ANSWERS-5% of seismic energy. Earthquakes occur along
ancient, pre-existing faults. Earthquakes here are usually shallow-focus.
QUESTION 5
Intensity - ANSWERS-A measure of the degree shaking caused by an earthquake.
QUESTION 6
Modified Mercator Intensity Scale - ANSWERS-Using buildings to describe the
intensity of an earthquake. Does not measure the earthquakes actual severity.
QUESTION 7
Richter Scale (ML) - ANSWERS-Based on the amplitude of the largest seismic
wave recorded on the Seismogram. This is able to account for the decrease in wave
amplitude as distance increases.

QUESTION 8
Liquefaction - ANSWERS-occurs when an earthquake's violent shaking suddenly
turns loose, soft soil into liquid mud.
QUESTION 9
Is able to create sand volcanoes if there is a layer of loose sand beneath the
overlying bed.
QUESTION 10
Material Amplification - ANSWERS-Loose sediments allow for seismic waves to
easily pass through in contrast to hard material that weakens the amplitude.
QUESTION 11
Seiches - ANSWERS-Rhythmic sloshing of water in lakes, reservoirs, or enclosed
basins.
