GEOLOGY

Detailed explanation-1: -A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore. What causes Tsunamis? The most common cause is a seafloor earthquake.

Detailed explanation-2: -Tsunamis generally reach a maximum vertical height onshore, called a run-up height, of no more than 100 feet above sea level. A notable exception was the 1958 tsunami triggered by a landslide in a narrow bay on Alaska’s coast.

Detailed explanation-3: -A tsunami is usually composed of a series of waves, called a wave train, so its destructive force may be compounded as successive waves reach shore.

Detailed explanation-4: -Tsunamis (pronounced soo-ná-mees), also known as seismic sea waves (mistakenly called “tidal waves”), are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite.

Detailed explanation-5: -tsunami, (Japanese: “harbour wave”) also called seismic sea wave or tidal wave, catastrophic ocean wave, usually caused by a submarine earthquake, an underwater or coastal landslide, or a volcanic eruption.
