Tsunamis Essay

Scientists used to believe that rogue waves could appear at any particular area of ocean only once every several millennia; however, recent oceanographic data suggest these waves are far more common than originally believed

Did you know Hurricane Sandy is known as “The Superstorm”? Sandy was one of the most destructive hurricanes in the 2012 Atlantic Season. On October 19, 2012, the meteorologists named the storm Hurricane Sandy. Sandy developed in the Caribbean Sea on October 22, 2012.Sandy was deadly, moved very quickly, but there are ways to survive hurricanes.

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.

-“The wave disturbance travels 300 m for each wavelength.” The speed of the wave does not determine how long the wave disturbance travels for each wavelength. We do not have enough information to determine that.

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

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

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

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

It is not correct to say that this means that the wavelength is .20s. The wavelength is the distance between the crests or troughs. It is a distance not a time. It is also not correct to say that the wave continues to travel for .20s before stopping. The wave may actually continue

The first type of waves are ocean waves which include: rogue waves, plunging, spilling, surging,and tsunami waves. Rogue waves are giant waves that can be over 100ft high; however, according to Tulane University physicist Lev Kaplan. These waves are caused by tsunamis that appear to come out of nowhere. Plunging waves occurs when the ocean floor is steep or has sudden depth changes, such as from

Sally was with Mrs. Chipley roaming the streets, so they could see Sally’s aunt Sarah. It was a stormy night at the end of summer.

Tsunamis are one of the most destructive natural disasters. A series of waves in an ocean or lake caused by the displacement of a large body of water is known as a tsunami, meaning ‘harbor wave’ in Japanese. A tsunami is also known as a tidal wave or seismic sea wave. Their wavelength is much longer than a typical sea wave, therefore tsunamis do not resemble normal undersea currents. Instead of appearing as a breaking wave, a tsunami may instead resemble a very tall tide or wave. Unlike typical wind-generated ocean waves, tsunamis are not caused by the gravitational pull of the Sun and Moon but instead are generated by the displacement of water. Tsunamis are very destructive and their causes and impact to the environment and to humans show this; so, looking at and understanding a past example of a devastating tsunami and preparing for one in the future can help save lives and lessen the overall damage.

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
