B. earthquake
C. earthquake beneath the sea
D. eruption of volcano under the sea

Answer

**Step-by-Step Solution:**

1. **Understanding Tsunami**: A tsunami is a series of ocean waves caused by any large and sudden disturbance in or near a body of water. This disturbance can be due to various reasons, but the most common cause is an underwater earthquake.

2. **Identifying Causes of Tsunami**: The main causes of tsunamis include:
- Underwater earthquakes
- Volcanic eruptions
- Landslides
- Meteorite impacts

3. **Focusing on Earthquakes**: Among these causes, underwater earthquakes are the most significant contributors to tsunamis. When an earthquake occurs beneath the ocean floor, it displaces a large volume of water, leading to the formation of tsunami waves.

4. **Conclusion**: Therefore, we conclude that a tsunami is primarily the after effect of an earthquake that occurs beneath the sea.

**Final Answer**: Tsunami is the after effect of an earthquake beneath the sea.
