How Dangerous Are Tsunamis, Really?

By Peter DD Vizard

Since 2004, when the first big Tsunami occurred, we all realize how dangerous a Tsunami can be. Tsunamis are mainly caused by lifting sea floor and transferring the energy to the water. They can also be caused by underwater volcanic eruptions and even landslides.
Thousands of people lost their lives and the coastal areas were completely destroyed. The problem with a Tsunami is nobody can predict when and where it happens.
Even a strong earth quake under the sea is not predicting how much power the wave has, when the Tsunami travels thousands of kilometers on the ocean surface to an island or continent.
Even today the U.S. Geological Survey is not able to tell us the potential risk level of a Tsunami. They have data of the earthquake, but they can only assume the danger of a Tsunami. Since the Tsunami in the Indian Ocean, we know how difficult it is to predict a Tsunami and its strength or direction.
Except for the largest Tsunamis in 2004, only a few Tsunamis have giant breaking waves. Often small Tsunamis are coming to the shores and are seen as strong and fast-moving tides.
Small Tsunamis happen every day. They are very often to far away from land or they are too small to have any effect when it hits the shore.
Researches provide information that The Pacific Ocean is creating most of the worlds Tsunamis. This is because of many existing volcanic undersea eruptions and overlapping sea plates. For example other countries are affected many hours later, when a large Tsunami occurs at the deep sea of South America.
Many scientists are working hard to install a global warning system for predicting Tsunamis, but the equipment for detecting and measuring dangerous Tsunamis is not giving enough data to provide good advice.
In any case it is better to warn the population, even when the waves are small and not noticeable as a Tsunami.
