The highest ever disaster caused by an earthquake occurred on January 24, 1556 taking a toll of 8, 30,000 lives in Shensi province of China. Affected people bear the risk of loosing their property, as the whole city gets changed into debris. There is double burden of evacuation besides the property damage, which is equally torturing as is the occurrence of an earthquake. After being evacuated people are compelled to live under the sky as the property is destroyed (Asimov 1998).
Powerful earthquakes put people and property in danger by swaying buildings and creating cracks beneath resulting in landslides. Such powerful earthquakes have caused huge destruction of property including bridges, water tanks, sewer, and utility services the world over wherever they have occurred. Damage increases multifold where soil is soft due to water saturation, which enlarges the circumference of ground movements. On slanting slopes, soil starts falling during the occurrence of earthquakes, causing landslides. Tsunami is an indirect reaction of earthquake, causing more loss of life and property than the earthquake itself because of powerful sea waves (USGS 1997).
The effect of earthquakes is measured through their intensity and magnitude. Intensity of the earthquake is measured by the violence of feeling its impact at different places of the affected area. The magnitude of the violence is decided by the effect on buildings,
grounds, and the people. The intensity scale of determining the loss of people and property is different for different countries. In most of the America, the Modified Mercalli Intensity Scale having 12 intensity levels is used. Earthquake of intensity I is hardly felt. Intensity II is noticed by people resting on the top floors of the building. Earthquake of intensity III is felt while remaining inside of the upper floor buildings. Effect of intensity IV can be

This has enabled the science to develop into the modern age on par with other sciences. The basic reason behind the occurrence of earthquakes is the push and pulls forces inside the earth’s mantle. The forces are high enough to swivel and twine the tectonic plates on the top causing earthquakes (Walker, 2007).
The author states that there are many similarities between the two natural phenomena that occur. The both cause widespread destruction if they occur in populated regions; both can be trigger each other. However, their occurrence relationship is not very strong and cannot be used as a predictor for their activity.
Again in the case of the recent Japan disaster, the most important water use was for the cooling on the nuclear power plant at Fukushima, northeast of Japan which was damaged by the earthquake and tsunami.
It focuses on the phenomenon of earthquakes and identifies the main components of earthquakes. In the past, earthquakes have caused severe and considerable damage to properties lives and communities around the globe. This paper therefore analyzes the scope and effects of these natural events and identifies the main elements of it.
This implies that even though earthquakes are natural occurrences and cannot be prevented; there are still ways through which they can either be deviated. It is also important for the government officials from countries which are risk experiencing this natural occurrence to come up with measures that will ensure security among its citizens.
Earthquakes in the Xi Chuan Province: An Analysis of a Disaster’s Representation Through Video, Print, and the Web and How these Affect Disaster Management Activities as Well as the Perception of the Calamity Within and Outside the Affected Region. The Xi Chuan basin is classified as a high seismic area because the region is located right where the Himalaya mountain belt and the Eurasian plate collide (Li and Chen 1003).
This paper gives an explanation of the formation, occurrences, causes, and how an earthquake forms through the tectonic plate theory. The crust and the uppermost part of the mantle are made up the tectonic plates that float over the molten rocks. The plates are in a continuous motion and move over and under each other colliding at each other, which can result in a stretch, bend, and breakings.
The paper uses a practical approach to examine earthquakes by evaluating five specific cases. These cases include major events in the 1755 Lisbon Earthquake, the 1906 San Francisco Earthquake, the 1964 Alaska Earthquake, the 1960 Chilean Earthquake and the 2004 Sumatra Earthquake.
Geologically, it has been shown that the province has had eleven earthquake of magnitude above seven. There has been also eight earthquakes with magnitude range of 6 to 6.9. The most current earthquakes in Sichuan Province are the
Despite the fact that today atomic theory is a well-known modern science cornerstone, such as germ evolution theory, throughout history, people had the belief that matter was perhaps constant and could randomly be broken down into
