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

Notes on Ground Motion Prediction Equations (GMPEs):

  • GMPE v4 can only be shown at the location of the stations because it takes into account local site effects, which depend on the location.
  • GMPE v4 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 v4 is computed using Rhypo, but plotted on Repi.
  • The standard deviation of GMPE v4 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
