ShakeMaps of Peak Ground Acceleration (PGA), in units of %g; Peak Ground Velocity (PGV), in units of cm/s; and Pseudo-Spectral Acceleration (PSA), in units of %g. The KNMI publishes ShakeMaps for induced earthquakes with magnitude bigger than 2.0 in the province of Groningen. A ShakeMap is a representation of the actual ground shaking produced by an earthquake. The ShakeMap represents a combination of automatically recorded strong 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 (V4). More information about ShakeMaps can be found at: http://www.knmi.nl/kennis-en-datacentrum/achtergrond/shakemaps-voor-groningen
