36
Answer 4 20

• Focus

37
Question 4 - 30

  earthquake
• Found at the surface

38
Answer 4 30

• Epicenter

39
Question 4 - 40

• Define each type of earthquake wave
• Compression
• Shear
• surface

40
Answer 4 40

• Compression -
• Primary wave, moves fastest, arrives at measuring
  station first
• Travels by expanding and compressing the ground
• Shear
• Secondary wave, slower
• Travels side to side
• Surface wave
• Occurs when compression and shear waves reach the
  surface, responsible for ground shaking and
  causing damage

41
Question 4 - 50

• Name given to earthquakes that occur after the
  big one

42
Answer 4 50

• Aftershocks
