What Causes a Tsunami?

Tsunamis are a series of large waves caused by earthquakes, water landslides, volcanic eruptions, or sudden movements of the ocean floor due to very few meteorite impacts.

However, strong seabed earthquakes are the cause of most tsunamis. Seismologists say that only earthquakes with magnitudes greater than zero can generate large tsunamis.

Including vibrations that occurred on the east coast of Japan on Friday - most of the earthquakes that caused the tsunami occurred in the subduction zone where crustal debris pressed against each other. Subsidence means that a tectonic plate slides under another tectonic plate and sinks deep into the mantle

Friction between the two slowly moving plates of the Earth's crust creates a large amount of earthquake energy released as an earthquake. When a strong submarine earthquake strikes a relatively short distance beneath the ocean floor, it suddenly pushes a huge piece of floor into the Earth's crust. This suddenly replaced a lot of seawater which turned into a tsunami spreading outward from every direction of the epicenter of the earthquake. Just like the ripple of the pond, it is a much bigger scale.

The tsunami that occurred in the open ocean seems to be just a small wave, but it is likely to grow rapidly when they reach a shallow water area before they hit the coastal settlement. A wave of up to 9 meters has appeared many times, and in the past it is believed that a maximum of 30 meters of tsunami occurred.

In the area closest to the undersea earthquake, damage is usually the most intense. That's because the fast moving waves hit the ground very quickly. The tsunami was emitted from the position of the seabed earthquake at about the same speed as the jet liner, but the vast space of the Pacific is so wide that the alarm system is in place to warn people on the road ahead.

Earthquakes, sudden destructive vibrations of the Earth are the result of the movements of the Earth's crevice plate (this is also the cause of volcanic activity). Tsunamis are large waves, usually caused by sea earthquakes. Earthquakes occur everywhere, but they are the most common (and most destructive) of the coastal areas. These types of disasters usually occur at certain times of the year, but they are caused by very specific atmospheric conditions due to the general climate. Due to the large duplication, these types of disasters are best considered together. Hurricanes are formed especially in the ocean and therefore mainly affect coastal areas. The tornado also forms a quite limited area. Thunderstorms occur more widely

It is important to understand the cause of the tsunami and how they are formed before truly understanding the damage and destruction that these natural disasters can cause. There are many reasons for the eruption and explosion of tsunamis, volcanoes, volcanoes, but the most common cause is an earthquake. Since the Greek historian Thucydides combined the tsunami of the Aegean Sea with the former earthquake in 426 BC, the relationship between the earthquake and the tsunami was more than 2000 years ago (Koenig, Science). However, in order to interfere with the tsunami, the obstruction is very large, under or under the sea, and must cause movement of the ocean floor. When an earthquake occurs, usually a piece of material falls into the Earth and the pressure rises. Finally, the locked area enters the cave. Suddenly the undersea suddenly turns upwards, and some areas sink when the tension is released. When this happens, irregular ocean will start competition.
