Magnitude
The size of the seismic waves; an increase of 1 in the scale represents an increase in amplitude of a factor of 10.
Amplitude
Caused when a material is compressed, bent, or stretched.
Elastic deformation

Tsunami
A rating scale that measures the energy released by an earthquake, taking into account the size of the fault rupture, the amount of movement along the fault, and the rock's stiffness.
Moment magnitude scale
The deformation of materials in response to stress.
Strain
Numerical rating system used to measure the amount of energy released during an earthquake.
Richter scale
Point on Earth's surface directly above the focus of an earthquake.
