EARTHQUAKES

• Ring of Fire

  Areas surrounding the Pacific Ocean experience high amounts of volcanic and seismic activity
• Earthquakes

  shaking of the Earth's surface resulting from the sudden release of energy
• Active Fault

  • fault where movement or slippage is expected to occur
  • areas that are prone to earthquakes
• Inactive Fault

  • fault that has ceased activity for a long time
  • does not disturb or break all layers of the soil
• Hypocenter

  location where the movement took place, also known as the focus
• Epicenter

  point on the ground directly above the hypocenter
• Fault Scarp

  elevated surface caused by the movement of the fault
• Magnitude

  amount of energy released by an earthquake as the ground shakes
• The more energetic, the higher the magnitude
• Richter Scale

  used to measure the magnitude of an earthquake
• Tsunami

  • harbor waves or waves that come into the bay from the ocean
  • huge destructed waves generated when an earthquake occurs underwater
