Tsunami Research Paper

The tsunami caused devastation in coastal communities in Indonesia and eleven other countries. More than 225 000 people died leaving families destroyed, children orphaned and people not knowing if their loved ones were dead or alive. 500 000 people were left homeless adding to the trauma of the disastrous event. Across the affected countries there were an estimated 5 million people deprived of basic services such as clean water and sewage. This lead to

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.

Throughout this unit, the Science in Practice class has been learning about natural disasters and the impact it has on humans and environment. The natural disaster that will be discussed in this report is the Boxing Day Tsunami, which occurred on the 26th of December, 2004. The tsunami took place in the Indian Ocean. Due to, two tectonics plates, the Indo-Australian plate and the Eurasian plate colliding, causing an underwater earthquake. Due to this awful disaster, people were killed, injured, diagnosed with diseases, homes and businesses were destroyed, the environment damaged.

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.

Magnitude of the earthquake was 9.5 out of 10, with a rupture zone of about 1,000 km. About 1,655 people were killed, 3,000 wounded, 2 million homeless, and about $550 million lost in southern Chile. The volcano actually triggered a tsunami that killed 61 people and caused extensive damage in Hawaii, the Philippines, Easter Island, Samoa, and California. Residual damage caused landslides and volcanic eruptions after two days and lasted for several weeks. There were four foreshocks with magnitudes of seven or upper, five aftershocks with seven or upper levels, and some volcanoes. The first tremors and aftershocks began on May 21, 1960 and lasted until November 1, 2016.

All along the coast of Central America the tsunami was observed. (February 4, 1965, Alaska Earthquake, Rat Islands, Magnitude 8.7) This earthquake was recorded at a magnitude 8.7 and caused a big tsunami of over 10 m on Shemya Island. It barely caused any damage, though. Just two months after the initial shock, an aftershock earthquake at a magnitude of 7.6 hit the same area. (March 28, 2005, Sumatra Earthquake aka Nias Earthquake) Just off the coast of Sumatra, Indonesia, was a devastating earthquake that killed 1,300 people. A majority of the devastation occurred on the island of Nias. The massive earthquake sparked a panic around countries along the Indian Ocean because there was a massive tsunami just three months earlier in December. ( August 15, 1950, Assam, Tibet Earthquake, Magnitude 8.6) There were at least 780 people who died in this 8.6 magnitude earthquake. Many buildings completely collapsed in areas of Eastern Tibet. Landslides and ground cracks/fractures ended up washing away and entire village. The village of Yedong collapsed into the Yarlung Zangbo River and literally washed

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

In the article, ¨Indian Ocean Tsunami; Then and Now¨ by Lucy Rodgers and Gerry Fletcher the text says, ¨About 228,000 people were killed as a result of the 9.1 magnitude quake and the giant waves that slammed into coastlines.¨ Anything can happen at any time, and everybody living in that area were not expecting a tsunami to hit out of nowhere, causing 228,000 of them to get killed. On page 48, the text says, ¨For as far as Ruslan could see, Meulaboh had become a lake, clogged with floating debris.¨ Everything in the city was basically gone, all because nobody saw anything coming and nobody was prepared. Finally, on page 78, the text says, ¨A man stared at him with wide, and bulging eyes. Unblinking eyes, rigid with death. Around him were several more corpses, caught in the brush like debris.¨ Thousands people got killed and hurt, because a tsunami hit out of

The U.S. west coast is very vulnerable to tsunamis. If a big quake hits Oregon’s fault, then it can generate tsunami waves up to 98 ft high. A tsunami in this region can threaten lives and damage the area from California to Alaska. Future tsunamis in the Cascadian Subduction Zone off the Pacific Northwest are possible.

too much weight is put upon an underwater slope. The underwater avalanches can then trigger

Good morning, at this moment we have breaking news, an catastrophic eartquake of 9 magnitude on the richter scale hit Japan a few minutes ago, this event caused a tsunami with waves up to ten meters. The epicentre was aproximately 70 kilometers east of the Oshika peninsula of Tokio and the hipocenter at an underwater depth of approximately 29 kilometers. The number of casualities is 24608 and the death tool is estimated around 15894 dealths. The lenght was aproximate six

Tsunamis have a very powerful, long reach. They can transport destructive energy from their source to coastlines thousands of kilometers away. Hawaii, because of its mid-ocean location, is especially vulnerable to tsunamis. Regardless of their origin, tsunamis evolve through three overlapping but distinct physical processes; generation by any force that disturbs the water column, propagation from deeper water near the source to shallow coastal areas, and inundation of dry land. Of these, the propagation phase is most understood, whereas generation and inundation are more difficult to model with computer simulations.

The 2011 Japanese tsunami will cost approximately 25 trillion Yen (298.66 billion dollars) the cost was about 6% of Japan's total economic output in 2010. It is also estimated that it would take 5 years to rebuild and recover from the damage. Due to the massive loss of money Japan's economy has fallen 1.3% which was then the world's second-largest it destroyed 138 000 13th which has a total cost of approximately 360 billion dollars the main area hit cost 6 000 lives and roughly 100 to 110 billion dollars. The total amount of people that lost their lives was around 22 000, with another 2 500 people missing. There were 6 million homes without power - 10% of Japan's population. There was 230 000 cars and trucks destroyed. Many roads, trees, shops and schools got destroyed.

In May 1960, the strong earthquake happened on the seabed of central and southern Chile triggered a huge tsunami, which causes tens of thousands of people dead and missing; coastal port completely paralyzed; 2 million people are homeless. The maximum wave height is 20-30 meters. Near vertical waves destroy houses and sweep away crowds. its influence in the world is largest. it is also one of the most serious tsunami disasters.
