    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 the coastal regions approximately 10 times each year. Tsunamis are often the main cause of death associated with the earthquake in the coastal region. There are four stages of tsunami formation namely initiation, split, amplification and lastly, run up…

  • Positive Characteristics Of Tsunami

    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…

  • Tsunami Research Paper

    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…

  • Cause Of Tsunami Essay

    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…

  • Causes Of Tsunami Essay

    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…

    high magnitude earthquake. The earthquake, which was said to have released the energy of roughly 23,000 Hiroshima style bombs, triggered a tsunami that followed shortly after (Nation Geographic 1). The Tsunami that followed caused mass destruction and is actually considered one of the deadliest natural disasters to ever be recorded (Taylor 1). This Tsunami, known as the 2004 Indonesian Tsunami, struck on December 26 at around 7:58 a.m. tore through and obliterated most of the coastline (Figure…

  • The Effects Of The Boxing Day Tsunami

    According to Szczucinski, a professor at the Adam Mickiewicz University in Polan, the Boxing Day Tsunami affected the coastal zone environments. There was extreme coastal erosion due to the large waves hitting shore. The salt water also had an effect by polluting the ground. He also states that the “surface waters caused significant changes in coastal zone ecosystems, where the run-up reached up to 31 meters above sea level and in some places the shoreline moved as much as 1.5 kilometers due to…

  • Samoan 2009 Tsunami Report

    Samoan 2009 tsunami report: What caused the earthquake and tsunami? On Tuesday the 29th of September 2009, a huge tsunami hit Samoa – as well as several other islands – and impacted many, leaving a path of destruction. Tsunamis are big waves that are generated from earthquakes, or volcanic eruptions that occur in the ocean. When the waves move inland they gradually gain height as the ocean gets shallow. So, the speed of the tsunami is related to the depth of the ocean. Tsunamis travel very fast…

  • Japan 2011 Tsunami Summary

    Japan 2011 Tsunami By Jayden Dwyer Summary On March 11, 2011, 231 miles northeast of Japan a 9.1-magnitude earthquake occurred 15.2 miles underwater. This is the biggest earthquake in Japanese history. The earthquake erupted along a subduction zone, this is where two tectonic plates meet and collide (convergent) with each other. Subduction is a process where one of the two plates slides underneath the other plate melting into the mantle, this builds up stress between the two…

  • Tsunami Vs Peshtigo Fire

    Disasters are catastrophes that have impacted many places and people. Two examples of disasters are the Japanese Tsunami and the Peshtigo Fire. The tsunami that struck Japan was a tragic event that destroyed many homes, buildings, and vehicles. After an earthquake hit, a tsunami, or a very long and high wave, formed along the coast. The wave came and destroyed many cities and towns. The Peshtigo fire was a fire that occurred in 1871. Many fires happened for the previous days and then one night,…
