Earthquakes: noticeable events, magnitude 2.5+, since 1975

Earthquakes are caused by a sudden release of stress along faults in the earth’s crust. The continuous motion of tectonic plates causes a steady build-up of pressure in the rock strata on both sides of a fault until the stress is sufficiently great that it is released in a sudden, jerky movement. The resulting waves of seismic energy propagate through the ground and over its surface, causing the
