Essay about earthquake effects


The earthquake struck at pm local time on the 12th of January, with a depth of around 13km. This relatively shallow depth meant that most of the energy of the earthquake was released close to the surface, resulting in a devastating catastrophe. The event….

Usually all earthquakes happen the same, but the way an earthquake actually occurs is such a spectacular process that everyone should get to know. They are created by many active fault zones within the Earth Fronabarger. Most earthquakes are made along faults, tectonic plate boundary zones, or even along mid-oceanic ridges Pidwirny.

Small earthquakes can be caused by volcanic activity, landslides, mine blasts, and nuclear experiments Science Daily. Sun and moon cause tremors by creating…. In consequence of location, scientists, geologists called this earthquake differently such as Loma Prieta earthquake, San…. Earthquakes Shira Miller Earthquakes are amazing natural disasters. An earthquake is a sudden and violent shaking of the ground. They are a big threat to people because they cause tsunamis, fires, and buildings to crumble on people.

One of the biggest earthquakes was the great Chilean earthquake. The quake happened on May 22, near Valdiva geology. The damage that the great Chilean earthquake caused including tsunami damage cost more than million U. The Great Chilean Earthquake The Great Chilean Earthquake, also known or called the Valdivia Earthquake, was the most devastating and destructive earthquake ever recorded in the twentieth century. It happened in the afternoon, around 5pm UTC time, and only lasted a short ten to fifteen minutes.

An earthquake is officially happening and it is beginning to demolish everything above Earth 's surface. The earliest ever recorded evidence of an earthquake occurred in the Shandong province of China in B. It is said that Aristotle stated that soft ground shakes more than hard rock in an earthquake in B. The interior of Antarctica has ice quakes, but occur within the ice sheet, instead….

Earthquakes In Haiti high by earthquake that killed thousands. Read More. Words: - Pages: 4. The Consequences Of Earthquakes Garbage is spread everywhere, lives are lost, buildings are razed to the ground, and cars have been tossed like soccer balls.

In about half of the cases, just before the rocks reach the rupture point to announce the event, small foreshocks announce hours, days or even months before the climax shock, that stress has become critical. The long series of post event tremors indicate adjustments. Sometimes, the break may be as large as the major shock. Unusual animal behaviour, fluctuations of ground water level in wells and springs and variation in the discharge of springs are the phenomena closely related to the development of fractures.

In China, about 90 per cent of the country is lying on the young and restless crust. Chinese have successfully employed most of the precursors in predicting major disasters and have specially mastered the art of closely monitoring and analysing normal behaviour of animals to forecast earthquakes. The Haicheng earthquake of February , of 7. Essay 5. Facts about Earthquakes : I. Earthquakes do not kill people, structurally unsound buildings can do.

Active thrust faults exist all across foothills of northern India, the north-east and into northern Pakistan. The subcontinent is sitting on the highly seismic Indian plate, with some major fault lines. In fact, there is no safe zone in India. Of late, the Indian plate boundary has become very active. It is on gradual move, pushing against the Eurasian plate by cm every year. All the plates of India should have a disaster management authority to deal with any eventuality.

Building of laws formulated after Bhuj earthquake to ensure the construction of quake-proof houses have not been implemented by any state government. India is among the few countries with no regulatory mechanism to control building activities. Disasters have left the years old Qutub Minar with slight tilt, but it has survived several quakes in its life time.

Essay 6. Classification of Earthquakes : The earthquakes are classified on number of bases. Of these the depth of FOCUS, the cause, the intensity and magnitude of earthquakes are very important. The earthquakes are broadly classified into Tectonic and Non- Tectonic types.

The tectonic earthquakes are directly related to the movements of crystal block along faults. They are generally very severe and area affected is often very great. A third way to classify the earthquakes is on the basis of their intensity, which is defined by the effects or degree of damage that an earthquake produces on the structure and features of the earth. This scale of intensity is adopted internationally. Charles F. Richter, an American Seismologist, devised the earthquake intensity scale.

This is based in the total amount of energy released during an earthquake. The vibrations are recorded on a strip of paper or photograph film and the diagram is produced as shown:. Most seismographs contain a heavy weight suspended from a support, which is attached to bedrock.

When waves from a distant earthquake reach the instrument the inertia of the weight keeps it stationary while the earth and support vibrate. The movement of the earth in relation to the stationary weight is recorded on a rotating drum. Some seismographs detect horizontal motion while others detect vertical motion.

The traces of the earthquake waves are usually recorded on a moving photographic paper as a series of zigzag lines. With the help of seismograph the distance between the recording station and the epicentre is located or determined. Essay 8. Seismic Waves Produced during Earthquake : At the time of earthquake three types of waves are produced from the focus Seismic waves are of three types—P waves, S waves and L waves.

P and S waves travel through the interior of the earth and are reflected and refracted as they enter core and mantle layers. These are compressional waves, which cause the material of rock to vibrate in longitudinal direction. The primary waves travel faster, therefore, they reach the seismic station first.

They pass through solid as well as liquid media. The velocity of P waves from 5. These waves are also called as Push waves and are similar to Sound waves. These are shear waves, which are transverse in nature, whose velocity is less than P waves. The velocity of these waves varies from 3 to 7 km per second.

The S waves travel through solids only and do not pass through liquid media. L waves travel along the surface and cause earthquakes. They are traverse in nature and their velocity is much less than P and S waves velocity varies from 4 km to 4. Essay 9. Earthquakes Resisting Structures : To build earthquake-resisting structure it is very essential to determine the probable intensity and magnitude in the concerned area.

The history and record of previous earthquake and the knowledge of geology of the area are helpful in this connection. Perfectly designed steel framed or reinforced ferro concrete structure possesses high degree of resistance from damage. It is recommended that in soft grounds where soil-bearing capacity is very poor, a concrete raft- foundation should be adopted for structures.

The height of large building should not exceed ft. The heavy loads near the top, like heavy stone work in coping and water tanks should be avoided. Bridges with screw pile foundation stand better to the shocks, than that of bridges with brick arches, and girder supported on stone work piers. In house construction light roof Low density concrete and polymer construction material are recommended. Careful planning can ensure that the streets are wide in relation to the height of buildings.

Many of the deaths caused during earthquakes are due to the collapse of tall buildings into narrow streets. Reinforced concrete houses are relatively stable. Doors and windows are provided in alternate positions. The light weight material such as wood, hard board and light weight fire proof polymer products are employed in the construction of residential building particularly in strong seismic zones as found in Japan.

The main aim of the engineer is to design and construct buildings, bridges and dams in seismic zones considering seismic co-efficient of the locality in such a way that they can minimise loss of life during an earthquake. Essay Effects of Earthquake : 1.

The second effect is one of disasters which make anything become dust in few minutes, and this disaster is a volcano. According to Diane and Tania, scientists have known that volcanoes are one part which causes earthquakes, but they research that this relationship also can happen contrary.

Volcanoes create a lot of hazards, and it is obvious that an small earthquake is a warning of an impending eruption. In addition, volcanoes can change the weather. They can cause rain, thunder, and lightning. Volcanoes can also have long-term effects on the climate, and they make the world become colder.

Fast-moving lava can kill people, and falling ash can make it hard for them to breathe. Hence, they do not have food and can die from famine and fires which are related to volcanoes. People can lose their possessions as volcanoes can destroy their houses, roads, and fields.

Landslides are also special disasters which cause a lot of troubles to humans. According to Diane and Tania, a lot of things can cause landslides such as heavy rain, wildfires, volcanic eruptions and human activities. On the other hand, earthquakes can easily create landslides which are terrible problems. On May 18, , a magnitude Helen, and it was the largest landslide that had ever happened.

Within about ten minutes, million dump trucks were destroyed by the largest landslide, and everything that it crossed disappeared April Therefore, landslides certainly cause damage to property, and this trouble brings losses to the economy of a country. Economic rehabilitation is also needed in the area that has experienced a landslide.

Besides, landslides steal many lives of humans and animals which we cannot predict and control. In conclusion, those disasters are effects of earthquakes: tsunamis, volcanoes, and landslides. The details of three bodies help people realize that humans cannot control anything in the natural world.

Thus, people have to learn more experiences and information about many disasters of the natural world to protect themselves. Besides, people also need to stop destroying anything which natural creates and try to follow the laws strictly. See Also Earthquake and Its Effect Read More.

When it happens, it causes the Earth to start shaking violently that causes massive destruction at the place. The strong movements inside the crust of the Earth or volcanic action causes a disruption on the Earth. It is a form of a natural disturbance that is characterized as concussion, and convulsion of the ground. This creates a shaking effect on the surface, that leads to speedy and strong vibrations at the place.

Due to the release of rock, a huge amount of energy in the atmosphere. When the effect of the Earthquake is strong, its vibrations are experienced in the neighboring districts too. Earthquake perceived as a life-threatening, and a hazardous natural disaster that has the ability to occur at any point of time, and anywhere on the planet.

Where mild earthquakes appear in the form of minor tremors, larger earthquakes come with strong tremors that starts off with slight tremors but transforms into violent shocks. The intensity, and magnitude of an earthquake is measured using scientific scales that includes Richter scale, altered Mercalli scale, moment magnitude scale, etc.

Earthquakes can happen due to various physical factors. This is perceived as a volcanic activity. This natural calamity can happen at any point of anytime and can cause havoc to life of living beings and beneficial natural resources. Earthquake implies a phenomenon that leads the Earth to tremble.

Earthquakes are a dreadful natural disaster. Greater the intensity of the earthquakes, greater will be the loss of property, and life. Earthquakes that are weak in intensity, goes unnoticed, whereas severe Earthquakes causes a lot of destruction to a place. Their unpredictable nature is what makes them highly dangerous. Depending on the way they occur, and the reason for their occurrence, Earthquakes are classified into different types.

It has an abundance of energy. This energy pushes these plates towards or far from each other. This movement causes build of energy between plates, and generates enormous pressure. This type of Earthquakes happens due to collapse in the mines, and caverns that causes seismic waves.

This type of Earthquake is weak in intensity. Also read: Essay on global warming. Government has laid down a few safety instructions that every person should follow when they face this natural calamity. Search Categories.
