Japan, a well-developed country, which is geographically located in East Asia, between North Pacific Ocean and the Sea of Japan, is one of the most influential countries in Continent of Asia. Many Western Countries are well developed as well like The United States, Australia and other European Countries. In response to the question if Japan is a Western, well the answer is yes. Geographically, Japan is not even located near those of Western Countries, but if we are going to look at it based on how the country’s Economic Status, it is very Western-like country. That is because they consolidated ...

Earthquakes and other natural disasters are common occurrences in the world since historic times. There are several methods that different civilizations use to avert the consequences of the disasters. In particular, earthquake is one such disaster that is not predictable, yet its impacts are great in the property and human life. Due to this phenomenon, the construction of house had to include earthquake resistant techniques. There are several methods that traditional societies use in constructing house that are earthquake resistant. Most of these methods utilize locally available materials. These include the following. - Construction technology that use ductile ...

In New Zealand, people lie at the interface of the Indo-Australian and Pacific tectonic plates. According to history, these two plates have been grinding against each other for millions of years. Nonetheless, the outcomes for these collisions have three distinct outcomes which vary according to the specific location within New Zealand. In between these two tectonic zones, lies the Alpine fault which extends to the south of New Zealand from Greymouth and disappears into the ocean approximately 12 km from Milford. The alpine fault reportedly has fractured four times since its formation at intervals of about 150-350 years (Van ...

Introduction

On 11 April 2012 two huge earthquakes occurred beneath the floor of the Indian Ocean, off the coast of North Sumatra. Registering a magnitude of 8.6, the first was followed by another of 8.2 magnitude, which scientists subsequently identified as an aftershock. Neither triggered a large scale tsunami, which scientists attribute to the movement being of the “strike-slip” type, rather than the “thrust” type. However, strike-slip earthquakes are normally of a ...

Japan is a mountainous region where arable land is scarce and therefore Japan is far from food self-sufficiency, importing 60% of its annual grains consumed (McDonald, 2011). Rice is a national crop in Japan, and the government has put subsidies and support means to encourage its farmers to produce rice in large quantities for its population. Once the earthquake hit Japan and consequently by the tsunami, the country was left with destroyed land and infrastructure. Lands were flooded therefore, agricultural activities couldn’t take place and, even after flooding the land could not be used because of the salt left behind ...

1. How do continents grow and how are they modified Continents arise due to movement of plates causing boundaries within the earth surface. Plates move through the oceanic crust along narrow zones between each other leading to the development of plate-tectonic forces. As a result, this forces leads to development of boundaries between the plates. This plates becomes the continents. Generally, continents arise because of continental drift that forces a single land mass on the earth surface to split and drift hence forming a continent. Their modification arises due to various plate boundaries that develop within the earth surface. These boundaries ...

Earthquakes may have varied effects on the ways in which they affect the human settlement and activities that are conducted on a daily basis. The natural disasters that result from the geographical activities of earthquakes affect the settlement patterns and the human activities that might be of use when it comes to earning a daily life. Earthquakes have adverse effects on the housing and settlement of people. They are forced to change the way they were initially structured which makes it difficult to cope with the new ways of life. They are also driven into hard economic situations where they have ...

Earthquakes are vibrations of the Earth that are caused by the rupture and sudden movement of rocks along faults or breaks within the earth's crust. The elastic-rebound theory is a model used to explain the origin of earthquakes. It illustrates the buildup of elastic strain from stresses within the earth's crust and the abrupt release of energy along faults as the rocks return or rebound to their initial state (Ristau 249; Hamblin and Christiansen 510). The point within the Earth where the earthquake's energy is generated by the initial slippage or movement is called the focus. The epicenter is the ...

Abstract

Natural disasters have always happened and will continue to happen. Unfortunately, there is a major difference in how developed countries prepare for and respond to natural disasters, compared to developing countries. When a disaster hits a developing country, the death rates are much higher than in a developed country, the recovery period takes longer and the long term economic impact is more severe. This paper looks at the causes for the differences and addresses steps a developing country can take to be better prepared for and respond against potential natural disasters. There is a distinct difference in the terminology disaster professionals use between the ...

Geography is one of the ancient earth science. The word ‘Geo’ meaning ‘Earth’ and ‘graphy’ meaning ‘to describe’ was first used by Eratosthenes, a Greek scholar in third century B.C. Geography is basically the study of the earth’s surface and associated changes and impacts associated with it. It is the study of the interactions of all physical and human phenomena and also the landforms created during these interactions. Physical geography is one of the main discipline of geographical science. It is mainly concerned with the study of the spatial patterns of weather and climate, soils and vegetation, water in ...

Interpretative essay on “UFO in Kushiro” by Haruki Murakami and “The swimmer” by John

Cheever. Haruki Murakami’s “U.F.O. in Kushiro” and John Cheever’s, “The Swimmer” are two fictional accounts with a similar message on the significance of tragedies in life on our perspectives and decisions. Based on the relationships and communications between the different characters, the conversations in the two texts seem ominous to reality but are in essence a keen explanation of the relationship between reality and the inner personal reactions to tragedies like loss. Komura and Neddy are the two main characters that are stylistically used to communicate how tragedies expose both the vulnerability and the consequent rediscovery of different ...

2011 Tohoku Earthquake and Tsunami

Introduction

The Tohoku earthquake that occurred in the Pacific Ocean on 11th March, 2011 at a shallow depth of 32 kilometers is by far the largest earthquake ever recorded in the Japanese history and the fifth largest in the world. The earthquake was of 9.0 magnitude with its epicenter located 130 kilometers off Sendai, Honshu, the largest city in the Tohoku region. This earthquake set off devastating tsunami waves travelling like a jet plane at the speed of 700 kilometers an hour (Sorkhabi, 2011). The waves that reached the altitude of 40.5 meters travelled up to 10 ...

The decision for Royal Caribbean International to determine whether to continue to make stops in the devastated Island Nation of Haiti and its Labadee beach is certainly one that has deep implications associated with it. In the wake of the utterly devastating Haiti Earthquake, even though research states that there will be no effect on the number of reservations made for the cruise liner, the company still has a moral and social obligation which is far greater than the profit motive. Although the Labadee beach has remained untouched by the earthquake, having guests stay in the same area where ...

Summary of the geotechnical and structural problems of the I-495 Bridge

The I-495 Bridge in Wilmington, Delaware experienced geotechnical and structural problems leading to its closure. According to structural engineers, the closure of the bridge was following an external force that caused the four pillars of the bridge to tilt. The 11-mile long bypass through the bridge remains closed for an unknown time. The tilting pillars were because of a shifting force on the earth surface, but the engineers had not yet identified the source. Engineers and workers are using shovels, and high-powered sensors to discover the main cause of the shifts on the ground (Nann, and Jeff 1). After ...

Imagine a typical day doing the usual chores of gathering supplies like water, cloth or food. The market is busy with bartering for things taken for granted in northern continents. Children were running and playing among refuse materials on dirty streets. Conditions were poor. Then suddenly, the entire ground and every standing structure began to shake and fall. At that moment, it seemed as if the whole world was crumbling around the people of a nation that was already hurting. A devastating 7.0 earthquake struck Haiti in January of 2010. Four years later, a helicopter tour would reveal that rebuilding has not ...

Understanding of Pompeii about Mount Vesuvius eruption in AD 79

When the Vesuvius erupted in AD 79, it caught the population of Pompeii by surprise and utterly unprepared. Though we know now that all the signs of possible volcano were there in AD 79 but the residents of those times had no idea of the warning signs. We only get to know about the tyranny through the preserved letters from Younger Pliny who was an eye-witness to the disaster. Through him and his account we have gained insight of the reactions and effect on the people caught in the natural disaster. Younger Pliny’s letters leave no shadow ...

The Powerful Ocean

The Powerful Ocean A great disorder Tsunami is composed of two words from Japanese namely "Kanji" and "harbor" meaning waves. It is the series of the water waves caused due to the dislocation of large volume of water. The wavelength of these waves is longer than the normal waves called rising tidal. The period ranges from minutes to hours called wave train. There are many reasons for this disorder to occur as landslides, volcanic eruption, Earthquake, underwater explosions and due to the disturbances above or below the water in the oceans. On entering into shallow water, their velocity ...

Introduction

This research paper discusses the phenomenon of earthquakes – the geography and distribution of where they occur, and the explanations of the forces and processes involved. The theory explains why they occur more in some places than others and describes related phenomena including volcanic activity.

The Research

The accepted theory of the cause of most earthquakes cites the continuous movements of huge sections of the earth’s crust (known as the lithosphere), which comprises tectonic plates (Earthquakes and Plate Tectonics” 1977), which are further classified as either oceanic or continental plates, dependent on their location on the Earth’s surface: beneath the ...

Preparing for an earthquake is an important training which everyone should be aware of in order to save lives. “Earthquakes are one of the most frightening natural calamities that carry destructive aftereffects” (James 31). It is a sudden movement of the earth that is being caused by unexpected release of strain that has being accumulated over a long period of time. This causes a sudden slipping or movement on the crust of the earth that is accompanied by a series of vibrations. There are also instances when aftershocks are felt later on also. Due to this there have been designed the instructions for ...

Abstract

The city of San Francisco experienced two earthquakes in 1906. This caused firestorms which lasted for days destroying life and property worth billions. The city residents were shocked at the sudden turn of events. This is because they could not come to terms with the massive loss they had suffered as a result of the earthquake. People lived in fear as they lost hope in their livelihood since they did not expect such a catastrophe to befall them. However, they quickly recovered and embarked on the reconstruction of their city. There were various causes of the earthquake. As much as such ...

Introduction

There are many reasons which have made up the modern day Haiti. The racial caste systems are what have made the mulattos consider themselves superior to the blacks. The Haitian revolution which occurred in 1791 to 1804 help make the republic to be the first to ever be ruled by black people. The settlement done between the French and Haiti is what started to make the country be in debt with other countries. The occupation of US brought about the formation of good roads, housing and health care. During the earthquake the US were the ones who provided more ...

Introduction

Over years, engineers strive to construct structures that have conventional designs and are capable of fulfilling the designed jobs effectively and safely. Even with all these design factors adhered to, accidents and unexpected loads caused by things like earthquakes, explosions, tornados, moving machine impacts and many other things make a well constructed building suffer damages. Because of such unforeseen accidents and abnormal loads are capable of causing many damage and loss of lives, engineers should provide an effective structural integrity to structures. Structural integrity could be achieved through proper judgment and sharing of ideas and opinions on how to come ...

Earthquakes

Earthquakes produce vibrations that are recorded, detected and measured with the use of the seismographs. Seismographs amplify the ground motions by a million times more than the motions beneath making a zigzag transcribes that are known as the seismograms. This data is relevant for the determination of the focal depth of an earthquake the time and the epicenter of the phenomena. In addition, approximations can be complete with relative sizes and amounts of force it produced. The focus hypocenter of the earthquake is the origin of the fault where rapture initiates. The depth in kilometers and map locations in longitudes and ...

An earthquake results from a sudden energy release in the earth’s crust that causes a seismic wave which in turn causes shaking of the ground and leads to devastating occurrences.

Introduction

Natural disasters tend to have significant implications. These include collapsing of buildings, which translate to loss of life and destruction of property worth a lot of money. Natural disasters include earthquakes, floods, volcanoes, and extreme weather conditions such as hurricanes, lighting, storms, and mass movements. Each of these natural disasters requires the design of the building to incorporate an element or a factor, which avoid or reduce the impact of the natural disaster or how it will resist the natural disaster. In the design of buildings, earthquakes are of significant importance since they result to a lot of damage in structures and ...

- Background Several of the Asia and Pacific developing countries are located in the world’s hazard belts and are subject to occurrence of natural disasters such as floods, droughts, cyclones, earthquakes, windstorms, tidal waves and landslides, etc. The major natural disasters that happen at times in this region are mostly due to climatic and seismic causes. Weather become increasingly unpredictable, communities and local governments are beginning to recognize the risks associated with the occurrence of increasing number of natural disasters and have begun to ask more questions. We all need to know what we can ...

Way back in the medieval period the tribal’s presumed that earthquakes were considered to be god’s anger which was caused due to his dissatisfaction. In the current times, however, the real explanation behind the cause of earthquakes has been found and today scientists understand the cause earthquakes and know how to deal with it. Scientists use different kinds of equipments to predict earthquake by detecting the seismic activity before it happens. The predictions might be based on various data – for example, research has proved that just before an earthquake a number of male toads abandon the place along ...

Earthquakes are destructive natural phenomenon caused by tectonic activity occurring along plate edges and faults. They generally have a trail of destruction owning to the large areas affected, as well as the suddenness and unpredictability. The higher the magnitude of the earthquake on the Richter Scale, the greater the destruction it is likely to cause. Damages include the destruction of property, loss of life, disruptions in vital infrastructural services such as power and water supply, transportation and communications. Earthquakes can also have a major economic impact.

An earthquake is a natural phenomenon caused by vibrations in the earth’s crust. These vibrations are caused when elastic rocks strain and abruptly ruptures and then bounce back. These vibrations can either be noticeable or catastrophic causing the loss of lives or property. Earthquakes are part of the earth’s evolution and cannot be stopped since they are natural. They are among the most destructive and unpredictable natural disasters that have left millions injured, dead and others homeless. Earthquake prediction has become technologically impossible and above scientists knowledge. The Chile earthquake which registered 9.5 is the largest ever recorded ...

Risk management cycle and strategy of disaster

- Introduction Recent studies on the climate have linked global warming to the occurrence of earthquakes. Even though it does not seem real that climate change would affect plate tectonics movement, scientists have managed to identify a probable linkage between the movement of plate tectonics and global warming. This provides in depth insight into the recent occurrence of strong earthquakes such as the 2010 earthquake in Chile, 2004 in Indonesia, and the 2010 earthquake that ripped Haiti. The past decade alone has witnessed three of the strongest earthquakes to ever hit the earth. Therefore there could a link between the movement ...

Research Motivation

The reason I wanted to research this topic is due to the fact that I was born and raised outside of Nashville, TN, and throughout my childhood and high school years there, I was aware of a potential for an earthquake in Nashville. In my community, we had learned early on about the possibility for earthquakes in places like California and Japan, but the thought of an earthquake here in my home town was really an afterthought. My sole opinion as well as opinion of many other citizens in the area was not directed at the threat of an earthquake ...

Earthquakes are one of the most damaging natural disasters that exist. Although scientists cannot predict exactly when an earthquake will occur, they can ascertain where one is likely to happen. Furthermore, engineers are working on designing buildings that will sustain the impact of earthquakes.

An earthquake is what occurs when two sections of the earth abruptly slip along each other. According to the Lisa Wald, “the surface where they slip is called the fault or fault plane.” The position underneath the earth’s surface where the earthquake begins is called the hypocentre, and the position immediately over it on ...

Geog 315: Assignment 2 Literature review

Introduction The Tohoku magnitude-9 earthquake occurred on March 11th 2011. Its epicenter was on the undersea floor of the Pacific Ocean, about 45 miles (72 kilometers) east of Tohoku in northeastern Japan, and at a depth of about 20 miles (32 km). The cause was the sudden movement at the junction of two tectonic plates – the Eurasian Plate rising over the Pacific Plate. The tremors lasted about six minutes, and caused a huge and devastating tsunami. Huge waves reached Japan’s coastline less than an hour after the earthquake itself, and in some locations travelled inland as far as six ...

Introduction

One of the catastrophes that the world faces today is earthquakes. An earthquake is formed when certain energy is released in the earth’s crust and as a result creates a type of waves referred to as seismic waves. It is the effect of the movement of these waves that results in an earthquake Not all parts of the world experience this but some countries like Japan are unfortunate as earthquakes are experienced frequently. Just recently Japan was faced with one which caused massive damage to the country as a whole. An earthquake cannot be predicted and thus victims of such a catastrophe ...

An earthquake of magnitude 7.0 in Richter scale, which lasted for the duration of 30 seconds, hit the Haiti region on January 12, 2010, and claimed an estimated 222,570 deaths. Haiti occupies the west part of the island of Hispaniola, one of the Greater Antilles islands, situated between the Puerto Rico and Cuba. The fault zone is called Enriquillo-Plaintain Garden fault, runs some 16 kms from Port-au-Prince, and at the intersection of the regions separating the Caribbean plate and North America plate. According to the estimation of the United States Geological Survey (USGS), several million of earthquakes ...

An earthquake is a sudden movement of the earth’s crust caused by seismic waves within the earth. Earthquakes also known as temblors can be tremendously destructive to artificial as well as naturally occurring features. With all the destructive energy that earthquake possess it is difficult to imagine that a few thousands of them occur every year, not with a destructive magnitude but in the form of tremors. Areas that are on the “Ring of Fire” are mostly hit by earthquakes because of the volcanic activity present in these areas. It recorded that eighty percent of the world earthquakes occur ...
