PGA regression (geo. mean of horizontals) in [cm/s2]

Notes on Ground Motion Prediction Equations (GMPEs):

  • GMPE v5 can only be shown at the location of the stations because it takes into account local site effects, which depend on the location.
  • GMPE v5 is computed combining 4 models (Lower, Central-lower, Central-upper and Upper) for the median predictions and 2 branches for the within-event variability (Phi).
  • GMPE v5 is computed using Rhypo, but plotted on Repi.
  • The standard deviation of GMPE v5 is composed by the variability at rock and the site-to-site variability, being combined in the most conservative way.

PGV regression (geo. mean of horizontals) in [cm/s]

To zoom in a chart, draw a rectangle with the mouse inside it.

The charts only display data within certain limits: 0.001 ≤ PGA [cm/s2] ≤ 5000
0.0001 ≤ PGV [cm/s] ≤ 500

PGA ShakeMap (max. of horizontals) in [%g]

PGV and PSA ShakeMaps (max. of horizontals) in [cm/s] and [%g]

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/
