What is a tsunami? I do not know. Tsunami is a series of giant waves. In Japanese, tsunami means ‘Harbor Wave’. And in Chinese? Just listen. A wave is created when energy passes through water. Moving air or wind provides energy to water, forming regular waves. While on the ocean floor, when a tectonic
plate suddenly slides beneath the other. The resulting earthquake releases tremendous amount of energy. This energy spreads outward from the point of earthquake, triggering waves that can form tsunami. Initially, these waves are small in size but
they travel at great speeds. However, when the waves approach the shore, the rising seabed obstructs the energy of waves. This slows down the speed of waves. But the energy flux must remain constant leading to an increase in height of waves. Thus resulting in tsunami.
