The statement is true; it is impossible to anticipate when an earthquake will occur.
An earthquake is defined as the shaking of the Earth’s surface caused by a sudden release of energy in the Earth’s crust, which causes seismic waves, also known as S waves. The type and intensity of an earthquake are determined by the seismic activity in the area.
- Earthquakes are caused due to sudden tectonic movements in the earth’s crust.
- When the tectonic plates slide over one another, there is a cause of orogeny which results in earthquakes and volcanoes.
- These disturbances cause vibrations that spread in all directions.
- As there is a relative motion of these plates, there is stress built up, which breaks by releasing the stored energy known as shock waves.
