Pacific Ring of Fire
A region around the Pacific Ocean known for frequent earthquakes and volcanic activity.
Why is the Pacific Ring of Fire active?
Why is the Pacific Ring of Fire active?
The Pacific Ring of Fire is prone to earthquakes and volcanic activity because it contains many tectonic plate boundaries.

Study Notes
- The Pacific Ring of Fire is known for frequent volcanic eruptions and earthquakes.
- The Pacific Ring of Fire is a region around the Pacific Ocean known for frequent earthquakes and volcanic activity.
- The Pacific Ring of Fire is prone to earthquakes and volcanic activity because it contains many tectonic plate boundaries.
- Normal faults occur due to tension, while reverse faults occur due to compression.
- A city that experiences frequent seismic activities is likely located near a tectonic plate boundary.
- Earthquakes are caused by movement along faults due to tectonic forces.
- Movement along a fault generates seismic waves by releasing stored energy from built-up stress in rocks.
- A strong earthquake recorded along a fault line indicates that stress was suddenly released, causing seismic waves.
- During an earthquake, a safe location is under a sturdy table.
- If no sturdy table is available during an earthquake, drop, cover, and stay away from windows or other hazards.
