 Where do Earthquakes happen?
7. Find an image of the seismograph. Label the P wave, the S waves,
the S-P interval and the amplitude of one of the waves.

Station A:
Station B:
Station C:
9. Copy down the distances you found from the S-P graph:
Station A:
Station B:
Station C:

12. By what factor does the scale increase? How many times bigger is
a 7.0 than a 5.0 on the Richter scale?
13. Copy down the amplitudes you found for each station:
Station A:
Station B:
Station C:
14. Based on your data, what magnitude of Earthquake do you
predict? Compare this to the actual Earthquake data. Where was the
Earthquake location?
