Note: The inventory data of the accelerometers was fixed on December 2018. On basis of this new inventory, the strong motion values (before and after) and the ShakeMaps (comparison) has been reprocessed in March 2019.
Note: A new web service is available to download strong motion parameters from the RRSM system: http://rdsa.knmi.nl/odcws/rrsm/1/
