Study Notes
Earthquake Waves
- Seismic waves are responsible for carrying the energy released during an earthquake.
- There are two main types of seismic waves: Primary (P) waves, which are compressional and travel fastest, and Secondary (S) waves, which are shear waves that travel slower.
Pacific Ring of Fire
- The Pacific Ring of Fire is a horseshoe-shaped area in the Pacific Ocean characterized by high volcanic and seismic activity.
- It extends along the coasts of North and South America, Asia, and Australia, containing around 75% of the world's active volcanoes.
Characteristics of Volcanoes
- Volcanoes are generally described as openings in the Earth's crust through which molten lava, volcanic ash, and gases are expelled.
- They can be categorized into several types, including shield volcanoes (broad and gentle slopes), stratovolcanoes (steep, conical shapes), and cinder cone volcanoes (small, steep hills).
Tectonic Plate Divergence
- When tectonic plates move apart or diverge, magma rises from the mantle to fill the gap, often creating new oceanic crust.
- This process can lead to the formation of mid-ocean ridges and volcanic activity.
Precautionary Measures for Volcanic Eruptions
- Precautionary measures undertaken before, during, and after a volcanic eruption are known as volcanic hazard preparedness.
- These measures include evacuation plans, public education on eruption signs, and monitoring volcanic activity to mitigate risks to human life and property.
