Topic The strategy of evacuation from earthquake affected area. Investigators The research conducted by Robert Olson for evacuation awareness in earthquake prone areas and to recognize the outlay for cost effective methods to develop evacuation attentiveness. The research conducted by Benjamin Wisner, on people’s susceptibility to natural disasters. The research conducted by Adams R. and Spence R. on the devastation caused by earthquake. Abstract The most terrifying and devastating occurrence in nature is undeniably an earthquake. An earthquake is shivering of earth with huge force, resultant of the strain released which was accumulated in earth from a long time.

Earthquakes result in huge damages and loss of lives. Vigorous shaking of earth leads to collapsing buildings, tidal waves and fire eruptions. During earthquake, the strategy adopted for the evacuation from the affected place can make a difference of life and death for people. There are various factors which need to be taken into consideration for establishing the effectiveness of the evacuation methods. These factors include the intensity of the earthquake, the distance from the epicenter, the geography of the area, and the immediate aftermaths of earthquake.

The immediate aftereffects of earthquake can result into a fire or the damages caused due to building collapsing. The strategy for evacuating patients from hospital or children from school is entirely different and need special deliberation considering the special requirements of the invalids and the children. Keeping these factors while formulating the strategies for evacuation will definitely lead to successful evacuation. The human needs to be extra careful to combat this wrath of nature. Earthquakes tops on the list of natural disaster known to humans as of today, a large extent of people globally faces wrath of earthquake every year but still treats it extremely unconscientiously due to this lack of awareness serious losses of human lives occur which can be avoided if they are provided with the emergency guidelines of what steps need to be taken throughout the earthquake and remedies past an earthquake.

Raising of Earthquake resistant structures is one of the basic needs to prevent human loss during a earthquake. To reduce the sociological impacts and humanitarian loss from disasters such as earthquakes, proper knowledge is the solitary most excellent means that can aid human being to survive and reduce losses from earthquake. IntroductionAggressive shivering of land due to the release of gases in the form of high pressurized energy from earths crust is known as EARTHQUAKE.

Usually landslides and volcano eruptions are generated from earthquakes. Earthquakes caused due to the movement and warping of earths crust are addressed as “Tectonic Earthquakes”. The geosphere of earth consists of several interlocked crustal plates persistently moving due to the slow eruption of gases and heat coming out from earth’s mantle & core.

Geological timescale is used to calculate the time of plate’s movement over another plate. When the geological timescale is raised and a fault occurs in these plates interlocking habit resulting in jammed plate, the slow but continuous eruption of heat & gases begin to congregate underneath the defective plate and converts into immense quantity of energy turned into seismic waves got erupted disbalancing the plate’s position creating cracks and landslides on earths surface. According to geologists, 90% of collective energy underneath the plate is used to crack the plate for eruption turning into enormous heat due to the resistance while, only 10 % of that energy converts into Seismic waves erupting onto the surface.

The heat generated by this process remains in the earth itself which is the main cause for the raise in temperature of earth. An earthquakes magnitude is calculated on the basis of data analyses collected by recording the flow of seismic energy.
