Topic of the Day- “Earthquake”
The shaking of the Earth's surface is called earthquake. The sudden release of energy into the Earth's lithosphere creates seismic waves, which eventually come to us in the form of Earth vibrations. Sometimes the intensity of an earthquake is so weak that it cannot even be felt and sometimes it is so severe that there is a devastation like 2001 earthquake in Kutch, Gujarat and 2015 earthquake in Nepal.
Causes of earthquake:
- The motion of tectonic plates is the most common cause of earthquakes.
- Volcanic eruptions are the second leading cause of earthquakes. Often earthquakes occur before or after magma rocks come to Earth with volcanic eruptions.
- Large scale mining work in underground mines is another cause of earthquake. Due to the pressure generated within the rocks, the earth usually vibrates.
- Artificial explosions or nuclear tests are also responsible for earthquakes. High intensity explosions such as nuclear explosions are a primary cause of earth tremor.
- Apart from this, the construction of large dams and reservoirs is also another cause of earth tremor at the regional level.
Types of waves:
Earthquakes are caused by the energy released through seismic waves. These waves are generally of two types- Body waves and Surface Waves. The body waves are further classified as:
P-waves - These waves are also known as primary waves. These are the first waves to reach surface. These waves are like sound waves. They travel through all three mediums - solid, liquid and gas. These waves have a tendency to vibrate parallel to the direction of wave propagation. These waves are responsible for the rotation and contraction of the object.
S-Waves - S waves come sometime after the earthquake and are called secondary waves. An important feature of these S waves is that they travel only through a solid medium. The vibrational direction of this S wave is perpendicular to the direction of wave propagation, forming crusts and troughs in the direction of their transmission.
The body waves interact with surface rocks thereby, generating surface waves which moves along the surface. These can also be divided into two parts -
- L wave
- R wave or Rayleigh wave
Shadow zone of Earthquake:
Shadow zone, the area of the Earth that does not record any kind of waves. For both P and S waves, a zone between 105° to 145° is a shadow zone. The zone beyond 105° does not record S-waves. The shadow zone of P waves is smaller than that of S-waves.
