Tsunami can be defined as giant waves that occur as a result of a sudden movement in the seas, oceans or large lakes. These waves occur as a result of movements caused by natural events such as strong earthquakes, volcanic eruptions, underwater landslides or meteor strikes. It is more common for tsunamis to occur, especially after submarine earthquakes.
What is a tsunami? Why and how does it occur?
Tsunami waves, unlike normal waves, travel at a much higher speed. While a normal wave usually travels at 30-40 km/h, tsunami waves can reach speeds of thousands of kilometers per hour. This causes tsunami waves to be felt at much longer distances and have a greater impact.
A tsunami begins as a surge in sea level. This fluctuation begins at a very small size in the deep oceans and grows as it approaches the shores. When tsunami waves reach shores, they reach a much higher wavelength than normally expected and invade the shores. Tsunami waves may look like ordinary waves many times, but this is very misleading. Tsunami waves usually come in the form of multiple waves, with each wave having a higher dimension than the previous one.
The effects of tsunamis can be quite devastating. Very high wave sizes can destroy coastal structures, drag people and change underwater surfaces. Therefore, preventive measures such as tsunami warning systems and evacuation plans are very important. Tsunamis are a reminder of the power of nature and that people must be prepared for natural disasters.
