Some helpful definitions:
* epicenter - The part of the earth's surface directly above the focus of a earthquake.

* tsunami - A tidal wave of local or distant origin that results from large-scale seafloor displacements associated with large earthquakes, major submarine slides, or exploding volcanic islands.

* The magnitude of an earthquake is a measured value of the earthquake size. The magnitude is the same no matter where you are, or how strong or weak the shaking was in various locations.

*  The intensity of an earthquake is a measure of the shaking created by the earthquake, and this value does vary with location.
