Study Notes
Tsunami Formation
- Tsunamis are large ocean waves generated by sudden disturbances in the seafloor or in the body of water above it.
- The main processes that can lead to tsunami formation include:
Causes of Tsunami Formation
- Underwater Earthquakes: Tectonic plates shifting and displacing a large volume of water, making it the most common cause of tsunami formation.
- Volcanic Eruptions: Explosive volcanic activity or the collapse of a volcanic structure can displace water, leading to tsunami formation.
- Landslides: Submarine landslides or landslides that enter the water can generate tsunamis.
- Meteorite Impacts: Large meteorites impacting the ocean, although rare, can produce significant waves.
Tsunami Wave Characteristics
- Displaced water forms waves that travel across the ocean at high speeds.
- As these waves approach shallow coastal areas, they increase in height and can cause massive destruction upon reaching shore.
