In areas of intense mining activity, often the roofs of underground mines collapse and minor tremors take place. Strong seismic waves can cause great local damage and they can travel large distances. Maintaining a green cover will also help to reduce the damage.
An example of an earthquake swarm is the activity at Yellowstone National Park. According to the scientific study with the help of Seismograph, there are some secondary waves and tertiary waves in the earthquake.
Sometimes the tremors are very severe. However, these are confined to areas of active volcanoes. There are various scales used to measure the intensity of shaking and the magnitude of an earthquake. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other.
Larger earthquakes on the other hand produce a storm of earthquake which results to unimaginable destruction.
It may be pointed out Essay earthquake speech it is not the intensity magnitude of Richter scale of earthquake alone which matters more as regards the human casualities but it is the density of human population and houses which matter more in terms of human deaths and loss of property.
But, it is not essential that the earthquakes should always occur in the same manner. On the Republic Day in there was a severe earthquake at Kutch in Gujarat.
Earthquake which occur under the ocean take the form of a tsunami. The land area measuring 24 km in length was raised upward because of tectonic movements. Earthquake may occur anytime in any part of the world. Rats, snakes, crows, dogs, fish and many other animals are helpful by their changed behaviour to inform about earthquakes beforehand.
But even weaker seismic waves can travel far and can be detected by sensitive scientific instruments called seismographs.
Primary waves, the fastest wave sent out by an earthquake; travel down into the earth rather than along the surface. The crust, the thin outer layer, is mostly cold and brittle rock compared to the hot rock deeper inside.
Earthquake has its long devastating history from the ancient time all over the world however its monotonous regularity makes us more fearful. Classification on the basis of Human Casualties: The direction of earthquake was decided by the position of frog receiving a ball.
The killer tsunami claimed more than, human lives in the affected countries wherein Indonesia, Sri Lanka and India stood 1st, 2nd and 3rd in the number of human casualties. For speaking this awareness we should use radio, televisions, newspapers and other mediums.
They can select any of the essays given below under various words limit accroding to their need and requirement: Krishna Brahman and Janardhan G. Damage to Human Structures: There are various forms of faults however three main types are normal fault, reverse fault also called thrust fault and strike-slip fault.Free earthquakes papers, essays, and research papers.
A Study on Earthquakes - 1. Calculate the total amount of energy released in the two-week period by adding up the energies for all the earthquakes you recorded.
Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave.
In fact, from earthquake magnitude 2 to 6, the energy release and damage is not huge. The classes of seismic measure for the modern buildings are 5 to 6. However, if the earthquake magnitude is bigger than 6, the energy release can be destructive even billions dollar loss of life.
Essay on Earthquake Short Essay on Earthquake. Following are the short essays on earthquake for students under words limit ofand words.
Students can use any of these according to their need and requirement in the schools. Earthquake Essay 1 ( words) Earthquake is the trembling or shaking movement of the surface of earth. ADVERTISEMENTS: Speech on Earthquake: Seismic Waves, Facts, Effects and Safety Tips!
An earthquake is the shaking of the earth caused by pieces of the crust of the Earth that suddenly shift. The crust, the thin outer layer, is mostly cold and brittle rock compared to the hot rock deeper inside.
