Abstract

We present correlation coefficient estimates between a number of ground motion intensity measures ( IM s), as measured from the NGA‐West2 database, with focus on the correlation of vertical–vertical and vertical–horizontal ground motion components. The IM s considered include spectral accelerations with periods from 0.01 to 10 s, peak ground acceleration, peak ground velocity, and significant duration (for 5%–75% and 5%–95% definitions). To facilitate their use, parametric equations are also fitted to the correlation models. Finally, the dependence of the obtained correlation coefficients to magnitude, distance, and Vs 30 is evaluated.
