Glossary

The macroseismic intensity classifies empirically the earthquake severity according to an ordinal scale of the effects produced by the ground shaking.

The earthquake magnitude measures the intensity of the seismic event, based on an appropriate processing of the seismic signal.

Continuous ground motion constituting the background noise for any seismic measurement.

Microzonation is the identification of separate individual areas having different potentials for hazardous earthquake effects.

This heading indicates the morphology of the site where the recording instrument is located.
