Animated Voice : Images Of Tsunamis

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

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.

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.

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 crust and top of the mantle make up the land but they aren't just one big piece they are made up of many pieces called tectonic plates, which look like puzzle pieces. The plate boundaries are made up of lots of fault lines, and most of the earthquakes around the world happen on these fault lines, Because the edges of the plates are rough, they get stuck but the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake. Some earthquakes happen out at the bottom of the sea which most of the time causes a tsunami because the earthquake opens the sea floor which then makes the water fill in the gap but when the gap closes again it pushes the water out which causes a tsunami.

The word tsunami comes from a Japanese word meaning “Long harbor waives”. Tsunami is much known and very common in Japan because thousands of Japanese have been killed and some suffered in recent centuries. Tsunami waves generally speaking cause a lot of damages such as, killing people, destroying building, and costing million of dollars. Moreover, a tsunami is a series of great sea waves caused by an underwater earthquake, landslide, or volcanic eruption. The 2004 Indian Ocean earthquake that is located on epicenter off the west coast of Sumatra, Indonesia, is actually one of the worst disasters in the history of Indian Ocean that generated by the most powerful 9.0 magnitude earthquake. An aggressive

How does an earthquake cause a tsunami? We live on Earths crust. The earths crust is broken up into many parts and fit together like a jigsaw puzzle. These puzzle pieces are called “tectonic plates” At times these plates move towards one another and push together. At other times they move apart away from each other. The plates usually move slowly so we do not feel the movement beneath us. There are times however that we do feel the movements. These movements that we feel are called earthquakes as they shake the ground beneath us. There are two kinds of plates one is referred to as the “continental plate” and the other is called the “oceanic plate”. Just as their names imply the plates that lie under the continents are continental plates and those that lie under the ocean are “oceanic plates”. As we have learned in class many of the worlds earthquakes occur in what is called the ring of fire. The ring of fire is a vast area surrounding the Pacific Ocean. The edges of some of Earths tectonic plates meet in this area. Since the plates meet up there they can bump into each other. They can also move away or slide past one another. When this happens it can cause earthquakes and volcanic eruptions. Another factor in this formula for earthquakes are something called faults. Faults are large fractures in the Earths crust. These fractures are found at the edges of the tectonic plates. This is where most earthquakes happen. When an

An average of two tsunamis occur every year through the world that damages the land nearest to it. Also on average every fifteen years a destructive ocean-wide tsunami occurs.

A tsunami can get very high all the way to the top of the empire state building that is a 100 feet.The highest tsunami is about 1720 feet that is very high for water and it is all caused by an earthquake.Have you ever been near a tsunami if you have not they are huge it can take out almost the whole of new york city.new york is huge but it is not near the ocean so it could not take it out. When I was in new york I got the chills because there was flood warnings and I got

On Friday at 2:46 p.m. local time, near the northeast coast of Japan, there was a magnitude of 9.0 disastrous earthquake occurred on March 11, 2011 (“Poster of the Great Tohoku Earthquake”, 2012). Earthquakes occur at fault when a fracture in the earth along which movement occurs. When strain builds up, the fault slips and earthquake is created. Earthquake, the most destructive natural disasters of all is caused by the movement of the tectonic plates in the lithosphere. The ground shaking is produced by a rapid released of energy and stress in the Earth. When the stress is release, it sends vibrations known as seismic waves that produced at the focus of the earthquake. Honshu earthquake is considered as one of the deadliest earthquakes and

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
