Cause And Effect Of Tsunami

The most noticeable difference between a tsunami and a hurricane is the cause of each. A tsunami is the aftermath of an underwater earthquake or volcanic eruption. The force of the earthquake or eruption, along with the moving of the tectonic plates, sends large amounts of water in all directions. The waves can be thousands of feet high when they reach the shoreline. These giant waves can arrive at a moment's notice with no warning. The tsunami is a large natural phenomenon originating from the ocean, but it is not the only phenomenon to start in the ocean.

That is the image of a tsunami and they strike somewhere in the world almost every year. Some archeologists say that a mediterranean tsunami hit the north shore of Crete about 3500 years ago which sent Minoan civilization to surrender to Mycenaen Greeks. In the fifth century B.C. the Greek historian, Thuydides, was the first to document the connection between earthquakes and tsunamis. The majority of tsunamis are in the Indian and Pacific oceans where the Tectonic plated collide and the one carrying dense oceanic crust dives under the more floatable one forming a deep ocean trench. Normally it happens smoothly, but sometimes they become stuck and friction strain builds up, then it releases energy which raise and lower the water above it which becomes a tsunami. Created from the seafloor up they grow in dangerous heights in shallow waters only because in the deep oceans it barely

Some believe that the 2004 Indian Ocean tsunami was caused by an Indian-Israeli-American nuclear test. The possibility that it was some kind of human intervention that destabilized the tectonic plates, an invention that is caused only in nuclear experiments and explosions. The most popular theory is that the Indian and U.S. military are the “main cause of the disaster by testing tectonic weapons, which use electromagnetic waves, thus triggering

Tsunamis are caused by earthquakes underneath the ocean, which can results in gigantic waves that cause devastation and change the Earth’s surface by causing radiation and causing underwater landslides. In the article “Is Santa Catalina Island Sinking or Rising?” it describes how an effect of tsunamis. It states, “A tsunami could have struck the coast from Catalina when the underwater landslide occured” (Los Angeles Times 2). Therefore, tsunamis can strike coasts and can create landslides underwater, changing the ocean floor by creating caves and canyons. Also, tsunamis can wear away beaches. When giant waves crash into coasts of masses of land, they can wear away the coast. Finally, tsunamis can cause radiation. In the article “Dangerous Tsunami Threat off U.S. West Coast,” it explains, “It [the tsunami] also damaged a nuclear power plant, causing a meltdown and spreading dangerous radiation in the area” (Los Angeles Times). Consequently, tsunamis can destroy and interfere with human made buildings which may contain toxic gases which may be released into the air and cause damage the environment. Incidentally, damaging the environment can lead to killing plant and animal life, and the Earth in that area could potentially become barren and

The Boxing Day Tsunami had occurred on the 26th of December 2004. The tsunami had started under water, in the Indian Ocean. The cause of the tsunami was that the Indo-Australian plate had subducted below the Eurasian plate, this process is called a convergent plate boundary. This resulted with an underwater earthquake, making waves approximately 20-30 metres high and travelling at speeds up to 500km/ph. Theses waves travelled throughout Indonesia, Sri Lanka, India and Thailand and left each country in terrible conditions. The earthquake that occurred underwater had

Tsunamis occur when an earthquake happens in the ocean and the energy goes to the water creating huge waves. Tsunamis are very dangerous they can be so strong that they wash away the city, harm thousands, and cause hundreds of thousands to billions of dollars in damage. “A giant tsunami along the West Coast would wash away coastal towns, destroy U.S. Highway 101 and cause $70 billion in damage. More than 100 bridges would be lost, power lines toppled and coastal towns isolated. Residents would have as few as 15 minutes’ notice to flee to higher ground, and as many as 10,000 would die” (Dangerous tsunami threat off U.S. West Coast). This shows what kind of damage this geo-process can

Since these earthquakes are caused by tectonic plate movement therefore displacing the ocean floor they are almost always accompanied by massive ocean waves, sometimes reaching heights of over 100 ft and reaching speeds of 500 mph, known as seismic sea waves or more commonly known as Tsunamis4. Alongside the catastrophic events that megathrust earthquakes ensue on an affected region these colossal Tsunami waves further destruct costal lines in their path, sometimes reaching many miles inland.

Distant tsunami: A series of gravity waves in the ocean originating from a source typically thousands of kilo-meters away from the shoreline that is inundated. These waves are produced by the displacement of the entire water column of the ocean by an underwater earthquake, landslide, volcanic eruption, or extra terrestrial impact.

The Tsunami that took place after the initial quake was caused by a portion of seabed rupturing upwards, and displacing a large portion of the water being displaced. This water traveled at 450 miles, at 8 feet tall, to the Chilean and Peruvian coast. Early viewers of the tsunami later reported waves being up to 10 feet tall. This rupture was believed to be caused by 2 unusually dense pieces of seabed that had been previously undetected by scientists, and consequently caused a large displacement of water. There were also small ruptures of seismic

The tsunami waves reached heights up to 128 feet at Miyako city and traveled inland as far as six miles. A tsunami is a series of large sea waves caused by a large displacement of water. The tsunami flooded an estimated area of approximately 217 square miles in Japan. The massive waves destroyed large three-story buildings where many people seeked for safety. Within hours of the first tsunami hit Hawaii and set off multiple warning to Canada, Alaska, South America, the United States, the Oregon coast, and the Pacific.

This generated one of the deadliest tsunamis known to mankind, killing over 230,000 people and leaving over two million people displaced. The epicenter of the earthquake was located in the Indian Ocean, right off the west coast of Sumatra. The tectonic plates beneath the ocean floor had been colliding and building up pressure for hundreds of years, until this day when subduction occurred between the Indian and the Burma plates. The process of subduction displaced billions of tons of water, creating waves that traveled towards the shorelines at hundreds of miles per hour and as high as sixty to one hundred feet. There was absolutely no warning for the people of Southeast Asia, as the tsunami progressed quite rapidly. (National Geographic,

Tsunamis occur when there is sudden movement in an extensive body of water such as earthquakes, landslides on the sea floor, major volcanic eruptions or meteorite impacts. The most common source of a tsunami is earthquakes, which are another type of geomorphic hazard that is caused by the friction and stress that tectonic plates put on each other. Tsunamis primarily occur in coastal or island regions where there is a tectonic border or what is known as the ring of fire. As shown in the diagram below the ring of fire is located along the coastal and island regions of the world.As a result of the Pacific Plate diving beneath the Eurasian plate, on March 11, 2011, there were 2 geomorphic hazards, a magnitude-9 earthquake struck north Japan, which caused a deadly tsunami that reached heights of 39 meters. The destructive dilemma was dubbed ‘The Great Sendai Disaster’. The earthquake was caused by multiple centuries of stress on the tectonic plates surrounding the island. The earthquake caused a tsunami that reached the height of 39 meters (128 feet). Japanese scientists had previously discovered that there was another tsunami just like the one in 2011 that took place in 869 AD. But their warning was unhindered. The tsunami, which occurred in 869 AD, was caused by the same tectonic fault as the 2011 tsunami. The epicenter of the earthquake was off the northeast cost of Japan leading to a devastating tsunami that killed many and left many wishing they were. The massive earthquake caused an upward wave that headed towards the city of Sendai. Researches have recently uncovered a thin layer of clay that lubricated the fault zone causing the deadly tectonic slip, thus creating a tsunami that could wipe out an entire city as it did in 2011.The aftermath of the 2011 tsunami and earthquake was not pretty; it caused many deaths, injuries, traumas, financial difficulties, destruction of property, health bills and the destruction of the landscape as a whole. The natural disaster caused nearly 16,000 casualties and there are an estimated 2,500 people still reported missing. Although drowning caused most deaths others include, crushed by debris, suicide and diseases caused by nuclear radiation (cancer) spilled from nuclear

The morning of December 26, the peaceful morning was cut short of by a massive earthquake that struck off Indonesia causing a deadly tsunami The earthquake was described as having the power of 23,000 Hiroshima bombs, reaching a magnitude of 9.0. After the tsunami started it travels 13 countries and left beaches filled

The 9.0 magnitude Indian Ocean earthquake was caused by subduction under the Indian Ocean. Earthquakes are usually caused by convection currents leading to subduction/convergent currents. Convection currents is caused by magma rising from the deepest part of the earth, then slowly cooling, sinking again then re-heating, then rising upwards basically repeating the rising and cooling then re-heating cycle over and over again. The plates are separated from each other and they move apart, the plates then obviously hit another plate right next to it causing subduction. This earthquake was caused on the Oceanic crust, in the Indian Ocean, creating tsunamis that caused disasters and thousands of life loss throughout the Indian Ocean basin. The

A tsunami is a series of huge waves occurring when there is a major disturbance on the ocean floor. Tsunamis often occur due to earthquakes, volcanoes, or landslides (Park 16). Underwater earthquakes may produce waves that travel in all different directions. Some tsunamis lose power and die out under water, others may produce large waves as they approach land. Tsunamis may look like an onrushing tidal wave as they approach land, but do not occur because of tides (Park 6). Their walls of water can move across the open ocean at speeds of up to 560 miles per hour. When the waves hit the coast, they can reach up to 100 feet (Park 5). The tsunami in Japan is believed to have occurred after two of Earth’s tectonic plates collided in the
