Earthquakes usually start at a depth of less than km below the ground. The point of origin, called the seismic focus or hypo-centre, is located cause of earthquakes essay the cause of earthquakes essay of seismographs.
Seismographs across the world are constantly noting the vibrations of the crust. Vibrations spread out from the hypocentre, like ripples in a pool of water. The location on the surface of the earth directly above the hypocentre is called the epicentre.
It normally bears the brunt of the destructive power of these vibrations. That is to say, this is where the maximum damage normally occurs. The extent of the damage depends on the strength of the vibrations or the energy associated with them. It also depends on the cause of earthquakes essay of population how many people live in an area and the way buildings are constructed.
The nature of the soil is another factor which determines the extent of damage. If the soil is loose and damp, the damage is greater than if it is hard and firm. This is why the severity of an earthquake is measured in two ways—in causes of earthquakes essay of its magnitude and in terms of its intensity. The magnitude of an earthquake depends on the energy of the vibrations. It is measured by seismographs on a scale called the Richter scale. The cause of earthquakes essay of this scale is from 0 to writing a comparison essay In other words, the vibrations of an earthquake measuring 6 on this cause of earthquakes essay would be 30 times more energetic than those of a quake measuring 5.
Earthquakes measuring 9 or more on this scale are rare. Those cause of earthquakes essay from 8 to 8. Even moderate 5 to 5. This scale measures the intensity of an earthquake over a range of I to XII, depending on the cause of earthquakes essay it has. Earthquakes of intensity level I, termed instrumental, are merely recorded by instruments, and are hardly felt by anyone.
An earthquake of intensity level XII is termed catastrophic. The most terrifying thing about earthquakes is that they occur without warning. This is what makes it so difficult to protect people and property from destruction.
