earthquake occurs is called a(n)___________.
A.
B.
C.
D.
Earthquake zone

Epicenter
P-wave
_____9. During an earthquake, the first type of wave that hits a seismic monitoring station
is the ______.
A. P-wave
B. S-wave
C. They both arrive at the same time.
_____10. The type of energy wave that is created during an earthquake that moves
thorough rock in much the same manner as energy moving in an ocean wave is
called______.
A. P-wave
B. S-wave
_____11. Which of the following statements about earthquake magnitude or strength is
true?
A.
Earthquake magnitude or strength is measured by the Mercalli scale.
B.
The amount of energy released by an earthquake increases at the same rate as
the rate of magnitude (1.0 to 1.0).
For each 1.0 increase in magnitude, the amount of energy released increases by
more than 30 times.
Earthquakes measured at high magnitudes occur more frequently than those at
low magnitudes.

cating%20the%20epi%20conf%20packet.pdf
Go to page 4 to get material for the question. Make sure you fill out pages 4-7.
Make sure data tables and maps are filled out. Print out material to hand in.
If you do this at home you will need a compass and a ruler to draw circles and
measure.
