earthquake magnitude
earthquake magnitude (earthquake intensity) The magnitude of an
earthquake can be estimated from its destructiveness using the
Mercalli scale. As this measure is also dependent on the local geologic and building context, it has been largely replaced by the
Richter scale, based on the amplitude of
seismic waves.
