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.
Essay on Cow
It had been an average day in the office, conference calls, report writing, fighting off the mosquitoes that plague us here in Haiti. My clock showed just 10 minutes until it was time to leave for the day, when without any warning the ground made slight movements, which rapidly became violent. The earth shook harder than I have ever felt before, I ran to the door but could not get out. I hid under my desk, my hand pressed up against the surface protecting my head, hoping it would hold up to the pressure of 2 stories falling on it. If I were buried under a ton of debris, would I ever get rescued? Was this the end for me?
As quickly as the earthquake started, the violent tremor stopped, everything became still again. Covered in dust, I scrambled shaking over the rubble by the office and made it out to the safety of the street outside. People were coming out stunned, some crying, some injured, some silent. A count of heads to check everyone was present showed one member of the team was missing, stuck under the rubble. Companions brought him out and they carried him unconscious on a piece of the gate on their shoulders to the nearest hospital where he later died. Several of the hospitals had already collapsed. Home, schools, offices -- the buildings we spend our lives in become our greatest danger.
Cars were left abandoned in the street, roads were impassable covered by collapsed walls, buildings, telegraph poles and crushed vehicles. We walked the long way home not saying much, amongst people praying, crying, hysterical. It was surreal. We made a large detour around the petrol station that had exploded but was still making uncomfortable noises. A couple of people were wailing outside a collapsed building, the broken sign on the wall showed it had been a university.
Communication in emergency situations is often not easy. The phone networks were either down or overloaded so it is impossible to find out if our friends were okay. I had no way of letting my family know that I had survived and just hoped that they wouldn't hear about the earthquake until tomorrow. We have no idea where was worst hit or how the rest of the country is doing.
Last night we walked home in the dark, slept, or tried to sleep in the space in the garden least likely to have a wall or building fall on it should the aftershocks cause more damage. I lay feeling the aftershocks through the night under a beautiful sky heavy with stars, kept awake by the loud singing, clapping and shouting at what must be a local church and by our local confused cockerel who spent the night letting us know he was still alive!
Today we walk back to the office in the stark light of day. We pass the collapsed hospital at the end of our street. We pass a man carrying his dead child, repeating out loud that he has his beloved dead child in his arms, not knowing where to go. We pass people being carried on all kind of makeshift stretchers, doors, blankets or whatever they can get their hands on to carry their loved ones to medical facilities for help.
We went up and down the main road 6 times today, each time more corpses appeared, some covered in sheets some just lying contorted and stiff and coated in the dust that covers the city. I wonder if their families know where they are? It is impossible to make even a wild estimate at the number of people who have died, are missing or affected by this earthquake, which measured 7.3 on the Richter scale.
In Canape Vert Park, hundreds of people are sitting on the street, in the small open space. The smell of urine and excreta is strong. As the days pass the corpses and waste will become increasingly pungent.
Supermarkets have either collapsed, been looted or are closed for fear of trapping people in collapses from the aftershocks. The only food we find for sale is some unappetizing fruit that a group of women are selling on the side of the road. The cost of water has already gone up. Food and drinking water are scarce. I wonder how long we can last on the food we have at home, maybe two or three days. People are currently searching for family members or are in shock. I am concerned about the possibility of unrest related to the lack of food available in the coming days. Haiti is not exactly the breadbasket of the region.
We attend an Oxfam staff meeting, we are a small organization yet 7 people had their homes destroyed and several other homes were damaged. Haitians are heeding the advice that it is dangerous to sleep in their beds because of the aftershocks. Most people are sleeping on the street.
Teams are organized to go to different coordination meetings and collect information about the situation here in Haiti. We suggest that those members who are not coming into work this week help dig out people still alive trapped in the rubble.
We go to the WASH cluster meeting with a group of organizations who work in Water, Sanitation and Hygiene to coordinate the WASH response. In an emergency many organizations come to help so we need to work together and organize who does what and where.
Streams of people with suitcases are leaving the city to stay with friends and family in other parts of Haiti and the Dominican Republic.
The earth moves almost constantly this evening. I feel queasy. This evening is colder. Not like England in January cold, but chilly. Just before midnight a large noisy trail of people pass our house, they are worried by the rumor that a Tsunami is coming and are seeking refuge higher up in the hills. It´s raining a little. Tonight Port au Prince is spending its second night sleeping under the stars.
Haiti is not known for having a good security record. We hear that all the inmates from the huge local penitentiary who were not killed by the earthquake have escaped.
Today we do a rapid appraisal of the communes where we have recently trained teams in emergency WASH (Water, sanitation and Hygiene) response. Visiting the open areas where displaced people are sleeping, the main needs we are told, not surprisingly are drinking water, food, medicines and latrines.
The WASH coordination meeting does not go as planned but in a good way. Several private water companies are offering their services to provide water to key locations in the city, which is wonderful news. These organizations will provide 80 trucks full of water. The international organizations including Oxfam need to organize storage and management of the water, which is an enormous task.
Unfortunately we also find out that our emergency stock, (the materials that we keep stored so that we came respond quickly when there´s an emergency) have become inaccessible following the quake. This is a huge setback as tomorrow we want to start distributing water. People are hungry and people are thirsty.
The most disturbing sights of today were not the piles of debris that just 2 days ago were homes and local schools. The sights that made me draw breath were the bodies. A neat row of 16 bodies carefully wrapped in sheets, the group of 20 at the Canape Vert roundabout some identified with ripped cardboard name tags, a pile with no sheet covering them, just thrown one on top of the other and the two bodies on the corner of a street, an adult motionless under a small dead child.
Today lots of people are covering their faces with scarves and face masks, they believe this will protect them from diseases spread by dead bodies. Red scarves are particularly popular. Red is believed to be the strongest color and helps ward off disease. It is true that dead bodies from cholera victims can spread disease, but just walking past the bodies of the ordinary healthy people that the quake has taken does not. But it is a link that people often make probably because of how traumatic it is to see the bodies.
We are told that a plane is sending emergency materials for us and it should arrive tomorrow! This is great news.
Today was spent preparing to distribute water. I visited a golf course, currently home to about 10,000 people. There are a lot of sick and injured people sleeping out here. I was looking for an appropriate place to mount a portable water storage container (a bladder).
I am really curious about why people are walking around with thick white cream smeared under their noses. I imagine it must be something sweet smelling to counter the bad smells here. In fact it is toothpaste put there supposedly to stop them getting ill!
We are still sleeping outside and will continue to do so for a few days to come. I am not sure what I miss more, sleeping in my bed or eating cooked meals! Tomorrow we have a long but hopefully really productive day ahead of us. We will start installing the water points and distributing drinking water.
