Mercalli scale

nounməːˈkalimərˈkalē ˌskāl
  • A twelve-point scale for expressing the local intensity of an earthquake, ranging from I (virtually imperceptible) to XII (total destruction).

    • The Mercalli scale is based on observations at the site and therefore reflects the effects of soil conditions, distance from the epicenter, etc.
