Why do earthquakes happen?
As the tectonic plate surface have faults the gets stuck while sliding and remaining parts keeps moving. Whenever the force of these plates overcomes the friction the energy gets released in the form of seismic waves and shakes the outer world.ere are thousands of earthquakes happens across the world everyday. But most of them are too small to be detect and some have the power to destroy everything.
