We present a refined time–frequency technique to extract surface waves.

We present a method to estimate the angular displacements induced by surface waves.

We compute rocking from real seismograms recorded during an aftershock of the 1999 Chi-Chi earthquake in Taiwan from seismograms of an aftershock of the 1999 Chi-Chi earthquake.

We compute torsion from seismograms of the 2010 Darfield earthquake in New Zealand.
