Fig. 6.From: Vibrations of the TAIPEI 101 skyscraper caused by the 2011 Tohoku earthquake, JapanSpectral amplitudes of rotation motion from the 11 March 2011, Tohoku, Japan earthquake: (a) for the Z component, (b) for the E–W component, and (c) for the N–S components. The spectra at different stations are shown by lines with distinct colors. Several vibration modes with the local peak amplitudes are denoted by open circles.Back to article page
