An earthquake is any seismic event that causes seismic waves. These can be caused by human activity or natural causes. For example, fracking often causes earthquakes which are human caused. Earthquakes often shake or displace the ground or surface of the earth near the epicenter and if the displaced earth is under the ocean, it will usually cause a tsunami. Most earthquakes are caused by geological faults but they can also be caused by landslides, mine blasting, and volcanic activity. Earthquakes are measured by overserving seismometers that are set up across the globe in strategic places for ...

The areas hit by the tidal waves were Sri Lanka, Indonesia, India, The Maldives, Thailand and the western coast of Somalia. This tsunami measured a magnitude of between 9.1 and 9.3 becoming the third largest earthquake ever to be recorded on a seismograph. It was a Megathrust quake. Such an incident occurs when a ...

Introduction

The development of Disaster Psychology into various spheres of knowledge aims at the analysis of the psychological reactions emanating from either anthropogenic or environmental disasters consequences. This concept provides new approaches to efficiently constructing short-term and possible long-term relief programs. Emerging through stressful instances such as disasters, individuals usually undergo and express certain psychological reactions like denial, anger, irritability, isolation, blame games (blaming others or self-blames), mood swings, feeling stunned and helpless, depression, fear of nightmares, and grief (Frey et al. 2010). The duration and magnitude of these psychological reactions differ and can at times be mild or acute, ...

Abstract

The direct effects of earthquakes could range from building collapses to the destruction of the infrastructure on the hindrance to water supplies and the water purification infrastructures. This paper highlights the details and the circumstances that followed the earthquake in San Francisco in the year 1906 and also the fire that broke out in the aftermath of the event. Further, we delve into how the earthquake later turned around to affect the environment, economy and the society of the area where the earthquake mainly struck and also the impact that it had on the surrounding areas.

The problems of hunger and poverty in developing countries appear to be of great importance nowadays. However, the issues regarding foreign aid tend to be disregarded and usually do not find proper reflection in the minds of politicians leading both supporting and needy nations. At the same time, hunger and poverty are not the typical characteristics of wartime, but rather evident images of the gap between rich and poor countries that has been widened over the past decades. It is important, therefore, to investigate the effects of war actions and peacetime on developing countries, and reveal the possible way ...

According to the estimation of the United States Geological Survey (USGS), several million of earthquakes ...

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 ...

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 ...

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 ...

Equilibrium Price and Quantity

The earthquake in Japan has affected the supply chain in the world including those of cars. As a result, there would be fewer supplies until Japan recovers from the earthquake. (Miyoung and Jim) Figures 1 and 2 show the demand and supply curves of Japanese cars would have been affected by the earthquake. Figure 1 shows the demand curve of Japanese car demand. It is the typical demand for Japanese cars. Figure 2 shows the shift of the supply costs of Japanese car. The situation is not a simple case of low inventory. So, it is not just a question ...

Before the introduction of Richter scale, the measurement of earthquakes was done using the Mercalli Scale developed in Italy by Giuseppe Mercalli in 1902. Mercalli scale involves the use of observations and estimation of the intensity by people who experienced the earthquake. The features to be observed include the effects on buildings, human beings and the earth surface in general. The initial scale by Giuseppe had a scale of 1 to 10 and was later revised to 12. A scale of one means that the intensity of the earthquake is low, and the effect is not felt while a scale of ...

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 ...

1. Wildfire risk assessment using Geographic Information System (GIS) is an essential tool for tracking the increasing number of fires around the world. NASA has updated maps available daily on its Earth Observatory website. The terrible July 2012 wildfire in Colorado was first reported on June 23 in Pike National Forest. The TERRA satellite was able to track the movements of the fire from space. It is hard to track a fire from the ground because a fire moves wherever the wind pushes it. Even today the map is available at http://earthobservatory.nasa.gov which shows the burn area of the fire. The ...
