Seismic hazard map

The majority of major earthquakes occur beneath the earth’s surface around fault lines, the places where tectonic plates meet. Under pressure, the plates shift suddenly which causes rock to crack and movements in the earth’s crust. The stored energy is released in the form of seismic waves of varying strength.
