Introduction
Tsunamis, also known as seismic sea waves, are massive ocean waves that are typically caused by underwater earthquakes, volcanic eruptions, or landslides. These waves can travel at high speeds across vast distances and can cause significant damage when they reach the shore. Tsunamis can be extremely dangerous and deadly, as they can flood coastal areas, destroy buildings and infrastructure, and cause widespread devastation.
Task
In the next part we are going to explain all about Tsunamis.

2. Causes of tsunami.
What causes tsunamis
Tsunamis are usually caused by large undersea earthquakes, which create powerful seismic waves that can displace large amounts of water. The displacement of water then generates a series of long waves that can travel great distances across the ocean, sometimes reaching heights of over 100 feet by the time they reach land. Other causes of tsunamis include volcanic eruptions, landslides, and meteorite impacts. However, the majority of tsunamis are caused by earthquakes.
3. Different types of tsunami.
Types of tsunamis
There are two main types of tsunamis: local tsunamis and distant tsunamis.
Local tsunamis are relatively small and occur near the source of the earthquake, volcanic eruption, or landslide that generated them. They typically affect coastlines within a few hundred kilometers of the source and are characterized by short periods between waves and high wave amplitudes.
Distant tsunamis, on the other hand, are much larger and occur far from the source of the disturbance. They are often caused by earthquakes that occur on the ocean floor, and they can travel thousands of kilometers across the ocean before reaching land. Distant tsunamis are characterized by long wave periods (up to an hour or more) and lower wave amplitudes, but they can still cause significant damage and loss of life when they reach shore.
Evaluation
If you really read the text about the information, so these are some questions that you should answer.
- Name the 2 cause of tsunami.
- Explain how tsunami forms.
- Types of tsunami.
Conclusion
To conclude, at the end of your reading, you are able to know better about:
- What is a tsunami.
- How tsunami works.
- What are the types of tsunami.
