What to Focus On

  • Direct sources: mining, volcanic eruptions, deep drilling
  • Indirect sources: gravitation, magnetic field, seismic activity, meteors
  • Gravity anomaly means a difference between expected and observed gravity
  • Earthquakes are caused by sudden release of energy along faults
  • Focus and hypocentre mean the same point inside the Earth
  • Epicentre is directly above the focus on the surface
  • Body waves travel through the Earth's interior
  • Surface waves move along the Earth's surface
  • P-waves are fastest and travel through solids, liquids, and gases

Common Mistakes to Avoid

The focus and epicentre are the same point.

P-waves and S-waves behave in the same way because both are body waves.

Surface waves are one of the two body waves.
