Answer 2

Concept introduction:

When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.

Explanation:

Given that, the topic earthquake.

We have to find, project on earthquake.

According to the question,

Anywhere on Earth where there is enough elastic strain energy stored to cause fracture propagation along a fault plane is where tectonic earthquakes can happen. If there are no imperfections or asperities along the fault surface that would increase the frictional resistance, the sides of a fault can only pass one another smoothly and seismically. Such asperities are present on the majority of fault surfaces, which results in stick-slip behavior. Following the locking of the fault, ongoing relative motion between the plates causes an increase in stress and, as a result, a buildup of stored strain energy in the area surrounding the fault surface. Until the tension is high enough to pass through the asperity and abruptly permit sliding over the locked area of the fault, the process continues, releasing the stored energy. An earthquake is produced as a result of the release of this energy as radiated seismic waves of elastic strain, frictional heating of the fault surface, and rock fracture. Elastic-rebound theory describes this pattern of slow strain and stress buildup broken up by sporadic rapid seismic failure. The amount of energy that is emitted as seismic energy during an earthquake is thought to be only 10% or less. A large portion of the energy from the earthquake is either transformed into heat produced by friction or is utilized to drive the formation of seismic fractures. As a result, earthquakes increase the Earth's temperature and reduce its elastic potential energy, but these changes are minor in comparison to the conductive and convective movement of heat out of the Earth's deep interior.

Final Answer:

Earthquake is one of the natural calamity. It occurs due to movement of tectonic plates.
