Essay on Tsunami

Tsunamis can start from anything that suddenly displaces the seafloor, causing water to compensate for it (Kusky, 2008, p.1). Tsunamis can also be referred to as seismic sea waves. Two tsunamis occur per year around the world, and one very destructive one every 15 years, on average (Department of Homeland Security, n.d.). One specific tsunami happened in the Pacific Ocean near Chile on September 16, 2015. A tsunami can cause massive damage, wreak havoc, and ruin anything it gets near. Some do not know that tsunamis have many causes, not just earthquakes. Normally, though, it will be an earthquake, landslide, or volcanic eruption that occurs minutes before the tsunami arrives (NTHMP, n.d.). One can also be caused by the movement of…

The movement of earth's crust is capable of shifting huge volumes of water, then it unleashes great and powerful waves. Among nature's most powerful forces of destruction, these waves are called tsunamis. The Japanese term means "harbour waves". Tsunamis are a series of large ocean waves of extremely long wavelength and a period which is suddenly displaced on a massive scale by an underwater disturbance such as an earthquake occurring on or near the seabed or a volcanic eruption. Tsunamis hit…

Introduction: What is a harmful problem that waves cause? Tsunamis cause mass destruction and death whenever they hit land. Tsunamis are seismic sea waves/ huge ocean waves that are created by undersea disturbances and earthquakes. There are 3 main types of tsunamis: local tsunami, regional tsunami and distant tsunami. A local tsunami affects coasts less than 100km away from it's source and generally hits within an hour of occurring and sometimes within 10 minutes. Local tsunamis are…

A tsunami is a seismic sea wave. Displacement of water forms a sequence of waves and this generally happens in an ocean or a large lake.Tsunamis are different because normal waves are caused by wind or tides, which is actually generated by the gravitational pull of the Moon and Sun. According to Source 1, the first recorded tsunami was back in 7000-6000 BCE and this was in Portugal but the primary cause is unknown. Since then there have been many tsunamis that have caused damage, two of the…

Tsunami Many natural and manmade disasters happen every year. Some minor, others life changing. The life changing experiences have quite literally changed these people's lives. One of these many natural disasters had this effects on people… this was the 2011 tsunami in Japan. An earthquake in the area caused a hurricane to start. This hurricane quickly destroyed the cities in it’s way and killed 20,000 people in the process. The disaster had many effects on the people who were there firsthand…

Tsunamis: what are these exactly, how do they occur, and why are known to be so deadly? Tsunamis are massive sea waves that are spawned from earthquakes generated underneath the ocean at tectonic plate boundaries. Although earthquakes are known to be the main cause of tsunamis, these enormous waves can occur due to occurrences such as rapid changes in the atmospheric pressure or volcanic eruptions. These waves are formed in a series, sometimes referred to as a “wave train.” There is never just…

Sea by Richard Lewis is based on the terrible tsunami of 2004. The tsunami happened on December 25th and was caused by a very large earthquake in the Indian Sea. The theme was that in times of great trouble and tribulation people will change their ways and become more respectful and helpful. ¨Within 15 minutes, tsunami waves were crashing the coast of Sumatra. At the north end of the island was a heavily populated region known as Aceh. There, waves reached 80 feet high over large stretches of…

Skull Found In Papua New Guinea Likely Belongs To World's Oldest Tsunami Victim In 1929, the 6000-year-old human skull was found in a site at Papua New Guinea. New research analysis has now revealed that the ancient skull likely belongs to the oldest tsunami victim in the world, and the catasthrophic event killed that person. Professor James Goff, the first author of the study and a UNSW Sydney scientist, says that the site where the Aitape Skull was found was once covered with flood caused by…

characteristics of a tsunami? A tsunami is a large series of long wavelengths and period (time between crests) which can vary from a few minutes to over an hour. A Tsunami is a natural disaster and can be generated by any large, impulsive displacement of the sea level. An example of this is earthquakes with a magnitude of 6.5 or greater, landslides into or under the water surface, volcanic activity and meteorite impacts. Two tsunamis occur per year throughout the world which inflict damage near…

Disasters are destructive and have a huge impact on people’s lives. The article, ”Surviving the Tsunami,” by Lauren Tarshis, is about the 2011 Japanese tsunami. Before the tsunami, the earthquake was different than others. Instead of having quick bursts of shaking, this quake continued for about 6 minutes. The massive earthquake prompted a giant tsunami. The tsunami, as high a 133 feet, advanced towards the shore and the students of Kamaishi East ran for higher ground. All of the students and…
