Essays the causes of tsunami


An earthquake can cause a volcano with its additional disruption and pressure. Magma is melted, liquid rock so of course, it is harmful to anything in its path. This sudden release energy that causes the seismic waves that make the ground shake.

When two blocks of rock or two plates are rubbing against each other, they stick a little. Great subduction zone earthquakes occur around the world where…. Surface waves: Primary and secondary waves affect the surface resulting in the generation of waves called surface waves. These waves are considered to be the most destructive waves. Volcanoes Plate movement can also cause another natural disaster called volcano. Under certain conditions, when plates are pushed or pulled together, volcanoes are created thus, both earthquakes and volcanoes tend to occur in the same place.

Earthquakes occur among many places on earth and to a variety of different degrees. Earthquakes are specifically common in the San Francisco Bay region in California. Scientists have made great strides in the process of learning about earthquakes and continue to do more work that will help them learn about earthquakes in the future.

Earthquakes occur when two fault planes strike one another resulting in the shaking of the earth. Home Flashcards Create Flashcards Essays. Essays Essays FlashCards. Browse Essays. Sign in.

This is a tsunami, an earthquake that is formed underwater. The sea floor abruptly deforms and displaces the overlying water from its equilibrium position.

Waves are formed when the displaced water mass, acting under the influence of gravity, attempts to regain its equilibrium. The main factor that determines the initial size of a tsunami is the amount of vertical sea floor deformation. A tsunami can also be generating from submarine landslides. During a submarine landslide, the equilibrium sea level is altered by sediment moving along the sea floor. The aftermath of this horrendous storm is shocking. A tsunami that is caused by an undersea earthquake is also called a seismic sea wave.

Scientists can calculate where and when a given undersea earthquake occurred and predict when the resulting seismic sea wave will reach shore. The scientists base their calculations on data provided by instruments called seismographs.

These instruments detect vibrations called seismic waves that the earthquake sends through the rock beneath the ground Phillip. An earthquake on land differs greatly than one underwater. The fact that there is water involved makes the situation even more tedious to handle. To detect an earthquake underwater is sometime impossible, the wave may come without any warning the wave may cause more death and damage than ground shaking. In addition to earthquakes similar ground shaker plays a key part in the causes of tsunamis.

However, even volcanic eruptions, landslides and comets or other heavenly bodies hitting the sea can be a source. When the tectonic plates of the earth positioned under the sea are disturbed, an earthquake takes place, causing the seawater to displace and erupt in sudden waves. These waves move further and further towards the shores. They can go unnoticed in the deep ocean but become more prominent as the water becomes shallow.

Landslides are another prominent cause of a tsunami. When heavy debris falls without warning with massive force into the sea, it causes a tremendous ripple effect. This ripple effect thus, causes tidal waves to form, which ultimately rise towards the land and cause massive destruction. During the eruption of a volcano on land, debris falls with a great thrust into the water body, causing the same ripple effect. Volcanoes can be underwater as well. They are known as submarine volcanoes. Tsunamis can further occur as a result of meteorological activity and human-made triggers.

When water washes away the shores with such colossal force, it damages the sewage system and freshwater. It also causes water fit for drinking to erode and contaminate. Because of the water being stagnant and polluted, numerous diseases like malaria affect a large number of people.

They become ill, and infections spread quickly. A tsunami may even destroy nuclear plants which result in emittance of harmful radiations. These radiations are fatal to the health of every living organism. Mass evacuations become necessary in areas exposed to radiations because they can result in cancer, death and can even affect the DNA structures.

The saddest effect of a tsunami is the loss of lives in huge numbers. Tsunamis hit suddenly, with almost no warning and hence people get no time to escape it or run away. They drown, collapse, are electrocuted, etc. Tsunamis not only cause massive destruction of life but also degrade the environment in a gigantic way. It uproots trees and destroys pipelines which lead to the release of dioxides, raw sewage and other pollutants into the atmosphere.

When these hazardous pollutants are washed into the sea, they also cause unbearable damage to the aquatic underwater life. When the waves of a powerful tsunami smash the shores, they destroy trees, cars, buildings, telephone lines, pipelines and other man-made equipment into bits and pieces.

Poverty rises in areas which get most affected by the wrath of tsunamis. The governments are also able to do little for their betterment immediately due to the high funding requirement and expenses. And how do they affect the world? Tsunamis can be caused by landslides or volcanic eruptions that occur on the ocean floor. Rarely, they can be triggered by large meteorite impacts. But most tsunamis are caused by an earthquake. Luckily, not all earthquakes cause tsunamis. They must be large earthquakes that occur under or near the ocean, and create movement under the sea floor.

When these earthquakes occur at a submarine level, the vibrations cause the ocean water to ripple and move. And the bigger the earthquake.. A tsunami is, in essence, an enormous wave. Or, to be more specific, a series of giant waves.

They most often occur in the Pacific Ocean due to the amount of ocean trenches, mountain chains, and volcanoes that line the ocean floor. The problem with tsunamis is the fact that their effects are somewhat unpredictable. They can strike hundreds of kilometers away from where the initial earthquake took place. Generally, places such as Alaska, Japan, the Philippines, and the west coast of the United States are at the greatest risk.

Tsunamis reach coastal areas the quickest, landing enormous waves on the shore in a manner that can tear buildings apart and sweep people and vehicles away. They flood areas quickly and have an energy that is often equivocated to the energy from multiple blasts of TNT. Tsunamis cause many people to lose their homes and places of business, and cost governments millions of dollars in repairs and assistance.
