Editing Modified Mercalli intensity scale (section)

=== Estimating site intensity and its use in seismic hazard assessment ===
Dozens of intensity-prediction equations{{sfn|Allen|Wald|Worden|2012}} have been published to estimate the macroseismic intensity at a location given the magnitude, source-to-site distance, and perhaps other parameters (e.g. local site conditions). These are similar to [[Engineering Seismology|ground motion-prediction equations]] for the estimation of instrumental strong-motion parameters such as [[peak ground acceleration]]. A summary of intensity prediction equations is available.<ref>{{cite web| url = http://www.gmpe.org.uk| title = Ground motion prediction equations (1964–2021) by John Douglas, University of Strathclyde, Glasgow, United Kingdom}}</ref> Such equations can be used to estimate the [[seismic hazard]] in terms of macroseismic intensity, which has the advantage of being related more closely to [[seismic risk]] than instrumental strong-motion parameters.{{sfn|Musson|2000}}
