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.
