Question
What are the main causes of Tsunamis?
Answer
The main causes of Tsunamis
- Submarine Earthquakes: The most common cause of tsunamis is submarine earthquakes. These earthquakes occur beneath the ocean floor when there is a sudden release of energy along tectonic plate boundaries. As the seafloor shifts during these earthquakes, it displaces a large volume of water, setting off powerful tsunami waves.
- Underwater or Coastal Landslides: Tsunamis can also result from underwater or coastal landslides. When large masses of sediment, rock, or debris slide into the ocean, they displace water and generate tsunami waves. These landslide-induced tsunamis can be triggered by various factors, including heavy rainfall, volcanic eruptions, or human activities.
- Volcanic Eruptions: Volcanic activity, especially explosive eruptions, can lead to tsunamis. When a volcanic eruption occurs either on an island or beneath the sea, it can displace water, creating a series of waves that propagate across the ocean. These volcanic tsunamis are less common than earthquake-induced tsunamis but can be highly destructive.
