Stress (or pressure) along plate boundary due to friction


The convection currents in the mantle beneath the Earth causes tectonic plates to interact (move).

When the plates move, stress builds up due to friction. When stress exceeds friction, the seismic waves is released from stored energy.

The seismic waves travels to the epicenter, where the earthquake originates. The earthquake is widely felt.
