Earthquakes are one of a handful of natural disasters that occur virtually
without warning. State-of-the-art seismic prediction methods provide
at best only vague probabilities of occurrence, with certainties measured
in decades. Yet earthquakes take place every day; a year without a
major, devastating quake in some part of the world is both fortunate and
rare.
The vast majority of earthquakes are a natural consequence of plate
tectonics, a mechanism through which the Earth’s crust has
been broken into large plates riding on convection currents
within the Earth’s fluid mantle. Tectonic plates, which are
created along ocean ridges (sea floor spreading) and sink at their
edges (subduction), do not move uniformly in either direction
or speed; where they rub at their boundaries, tremendous
stress is produced. The sudden release of this stress — the
potential energy stored within deformed rock being converted into the
kinetic energy of seismic waves — is what we call an
earthquake.
