What is a Tsunami?
A tsunami is a large wave caused by a sudden displacement of a large volume of water, usually an oceanic earthquake, landslide, volcanic eruption, or other underwater explosion. When the displacement of water is suddenly and catastrophically large, it generates a large wave called a "tsunami".
How does a Tsunami Form?
A tsunami is formed when a large volume of water is suddenly displaced, such as when an earthquake occurs on the ocean floor and causes a vertical displacement of the seabed. This displacement sends a wave through the water that can travel long distances without much loss of energy. As the wave approaches the shore, it may take on a more shallow angle and increase in height due to the shallower water depth.pptsupermarket.com

Dangers of a Tsunami
The most significant danger of a tsunami is the damage it can cause to coastal areas. Large waves generated by the tsunami can cause significant structural damage to buildings, roads, bridges, and other infrastructure. The strong currents generated by the tsunami can also carry away vehicles, boats, and other objects and sweep them into deeper water. In addition to the physical damage, tsunamis can also cause significant environmental damage by washing away soil and pollutants and depositing them in other areas.pptsupermarket.com
Preparedness for a Tsunami
Preparedness for a tsunami is crucial to minimize the impact of the disaster. People living in coastal areas should be aware of the potential dangers of tsunamis and take necessary precautions:
Conclusion
Tsunamis are powerful and unpredictable natural disasters that can cause significant damage to coastal areas. Understanding the characteristics and dangers of tsunamis and taking appropriate precautions can help minimize the impact of these disasters.pptsupermarket.com
