Earthquake Essay 1 (100 words)
Earthquake is the trembling or shaking movement of the surface of earth. It is a sudden violent shaking of the earth surface occurs naturally and causes great destruction because of the strong movements within the earth's crust or volcanic action. It is a natural disturbance which can be characterized as convulsion or concussion of the ground. It originates at any point within the crust and pushes a mass of rock to slip suddenly. A huge energy gets released and travels through rocks as waves, which causes vibrations and shaking of the earth surface. The word earthquake reveals its meaning very clearly (earth means ground or soil and quake means shake or tremble).
Earthquake Essay 2 (200 words)
Earthquake is one of the dangerous and life threatening natural disaster which can come anytime and anywhere on the earth. Most of the earthquakes come with minor tremors however larger earthquakes with strong tremors generally begins with slight tremors but soon gets changed into more violent shocks. Stronger earthquakes generally end up with huge and forced vibrations at long distance from the main point of arousal. It gradually diminishes with reduced aftershocks. The focus of earthquakes becomes the subterranean point where it originates. Magnitude and intensity of the earthquake can be measured with the help of variety of scales such as Richter scale, moment magnitude scale, modified Mercalli scale, etc.
Earthquake is a life threatening event that responsible for the huge damage to the living and non-living beings. Earlier, it was quite hard to imagine the intensity of the earthquake before its occurrence. However, now-a-days, it has become easy to estimate the magnitude and intensity of earthquake because of the instrumental advancement in the world. People, in the ancient time, believed that earthquake occurs as mother earth was angry with them. It was Aristotle (a great Greek philosopher) who relate the occurrence of earthquake to some physical factors. According to him, the compression of air within the arch escapes cause shakes of some part of the earth surface and called as volcanic activity.
Earthquake Essay 3 (300 words)
Earthquake is a natural calamity can occur anytime and anywhere on the earth surface, cause lots of disturbance of to the living beings and useful natural resources. If we think about the earthquake, we also think that nothing is more destructive than this natural calamity. Earthquake has its long devastating history from the ancient time all over the world however its monotonous regularity makes us more fearful. Earth crust consists of several unfixed solid rock faces which move slowly below the surface under the range of millimeters to kilometers. The rate of movement increases with the thickness of plates. Such huge moving plates get separated from other plates and get out of their boundaries. Earthquake occurs when such moving plates clash with each other and separate.
Sometimes volcanos (located around edges of the Pacific Ocean, known as Ring of Fire) bursts and releases lots of lava, gas, etc which causes pressure and imbalance within the earth surface and produces earthquake waves in the surrounding areas. Thus, volcanic activity within the earth surface is one of the reasons for earthquakes. Faults created by the volcanic activitiy are filled up by the strong earht surface movement which causes tremor. Everyone should take care of them when earthquake occurs by following some precautions like:
- People should stay calm and stay inside or outside the door but away from windows, buildings and power lines.
- They should stand against the wall near to the center of building, at doorway and crawl under some heavy furnitures like a desk or table.
- Never use flammable things like matches, candles, or any other flame as they caught fire with broken gas lines.
- Never use elevators as they may stuck.
- If someone is in the running car, he/she must stop the car and stay inside until the earthquake stops.
Long Essay on Earthquake
Earthquake Essay 4 (400 words)
Earthquake is a natural calamity which has power to destroy human lives in few seconds. It is lonely responsible for the huge damage to living and non-living beings. Earlier, people were unaware of the reasons of earthquake occurrence and the extent of damage. They believed that earthquake occur whenever mother earth become angry with them. It was Aristotle (a great Greek philosopher) who made people aware that earthquake occur because of some physical factors. He told that, some parts of land moves whenever air compressed within the arch escapes which is called as volcanic activity. Earthquake waves cause movement in the surrounding areas because of air pressure and imbalance.
Another reason of earthquake occurrence is isostatic adjustment. Earth surface contains some raised and depressed blocks which make balance of earth surface however the balance disturb when blocks moves revolving on units of axis. Raised blocks get down and cause imbalance on the earth surface which inturn cause earthquake. Generally, it occurs in the volcano prime areas, under the feet of mountains and hills. However, it is not sure that earthquakes do not occur in other places. Earthquake may occur anytime in any part of the world. Some of the earthquakes become weak however some of them become very strong with huge force which may shake the earth suface far away from the centre point.
Earthquakes with huge intensity become really dangerous and cause severe damage. According to the scientific study with the help of Seismograph, there are some secondary waves and tertiary waves in the earthquake. There are various measurement scales which can accurately measure the intensity of earthquake such as Mercall’s scale, Richter scale, moment magnitude scale, etc. Himalaya zone, the Ganga, Deccan Plateau, the Brahmaputra valleys, etc are the earthquake prone areas in India. Kutch (Gujarat, India) earthquake of the year 1819 was so massive (calculated 8 on Richeter Scale) and affected a huge area (around 5000 square kilometers depressed by 15 feet and 1500 square kilometers raised by 50 feet). More than 10000 people were killed in the earthquake event of Latur and Osmanabad districts of Maharashtra on 30th of September in 1993.
Earthquake is the result of release of elastic energy after forceful tectonic plate movements. Elastic energy released in the form of seismic or shock waves which travels for a long distance outwards in all directions from the centre point (a place of maximum destruction). High-rise buildings and ancient structures of the cities (like Delhi) can be badly affected by the seismic force of earthquake.
Earthquake Essay 5 (600 words)
Earthquake is a very dangerous natural disaster which occurs as a sudden shaking movement of rocks in the earth's crust. Some of the earthquakes of low intensity become less dangerous however earthquakes having high intensity become very dangerous and can be extremely violent especially in the areas it occurs. There is no any fix duration for the occurrence of earthquake, it may occur anytime and anywhere for any duration. It may be brief but repeat many times a day. Earthquake is the result of sudden energy release within the surface of earth. This released energy under earth crust creates powerful seismic waves which travel through the earth surface. The frequency of waves and type and size of earthquake is measured by the help of seismology which involves the use of seismometer.
Large earthquakes may destroy things to a great extent as they take down huge buildings, cause injury and thus death of people. There are various scales used to measure the intensity of shaking and the magnitude of an earthquake. The scale showing magnitude 3 or less indicates that the earthquake is less harmful however the scale showing magnitude 7 or more causes huge level damage over a wide range of area. Earthquake which occur under the ocean take the form of a tsunami. It is a giant form which can cause death and destruction to the living and non-living things. High intensity earthquakes give rise to the landslides in the surrounding areas.
In the ancient time, people in China were used a device in order to guess the occurrence of earthquake. The device was similar to the jar having dragons on top and surrounded by frogs with open mouths. They guess the occurrence of earthquake by the exchange of fitted ball in dragon's mouth to the frog's mouth. The direction of earthquake was decided by the position of frog receiving a ball. This device was an effective tool in the ancient time to figure out the origin of an earthquake.
Causes of Earthquake
- One of the main reasons of the earthquake is plate tectonics which causes tectonic movements in the earth surface. Tectonic plates under the earth surface collide to each other and ride over the other which becomes the reason of mountain formation, earthquakes and volcanoes. This process releases a huge level of energy which creates a force and thus surface movement.
- Geological faults are also the reason of earthquakes. There are various forms of faults however three main types are normal fault, reverse fault (also called thrust fault) and strike-slip fault. Normal faults generally occur in the areas with extended crust, reverse faults occur in the areas with shortened crust and strike-slip faults occur in the areas where two fault sides slip horizontally.
- Most earthquakes become the part of a sequence of earthquake clusters which can recur in a regular pattern and related to each other in terms of location and time. Such earthquakes cause less damage however larger earthquakes (mainshock) create a foreshock (an earthquake of smaller magnitude) and cause much damage.
A series of earthquake can occur in the variety of earthquake storm whenever earthquake hit a fault in the clusters. Tsunami is a dangerous form of earthquake which occur as a result of a chain of fast moving waves in ocean because of powerful earthquakes. It is a very serious challenge for the people's lives, safety as well as earthquake engineering as they can engulf coastal areas, swipe away whole city, damage houses and many more. It is sad to say that it cannot be prevented however people can be warned through various warning systems to run away and save lives.

Natural Disasters Essay
Our Earth has suffered a great deal from reoccurring natural disasters that have repeatedly put a strain on people’s lives. A natural disaster is a sudden event, an accident or a natural havoc, that causes great extents of damage or multiple deaths. Over these past years a numerous amount of these disasters has been seen happening all around the world. Tragedies of towns getting torn apart were reported as well as the occurrence of many deaths, disabilities and shelter damage. People have been losing relatives, friends, shelter and property. Even though these disasters cannot be stopped from occurring, recognizing their danger and their effects is essential.
Natural disasters may occur in many different forms including but not limited to floods, earthquakes, and volcanic eruptions. There are a variety of different natural causes that lead to these disasters starting from a change in weather, all the way to deep heat under the earth’s layer. One of the most recognized natural disasters is “The Yellow River Flood”. The Yellow River Flood is known as the most vigorous, and by far the worst flood in human history. It has also been ranked to be the second deadliest natural disaster to ever occur. This unfortunate event occurred in September of 1887, when the Yellow River over-ran the dikes in China's Henan Province. The flood destroyed 11 large Chinese towns along with hundreds of villages, leaving millions homeless. The flood covered an extensive widespread of 50,000 square miles, unfortunately killing approximately 900,000 to 2,000,000 people.
Another well-known disaster is the Indian Ocean Tsunami. It was caused in December 26, 2004 by an earthquake that approximately had the energy of 23,000 Hiroshima-type atomic bombs. The 9.0 magnitude earthquake was under the Indian Ocean, close to the west coast of Sumatra Indonesia. Within a few hours of the earthquake, killer slammed into the coastline of 11 Indian Ocean countries, damaging...
