A ShakeMap is a representation of the actual ground shaking produced by an earthquake. The ShakeMap represents a combination of automatically recorded ground motion values, in the accelerometer stations around the epicenter of the earthquake, with the Ground Motion Prediction Equations (GMPE), for the places where there are no stations around. This GMPE is specially developed for Groningen (v5). More information about ShakeMaps can be found at: http://www.knmi.nl/kennis-en-datacentrum/achtergrond/shakemaps-voor-groningen"
