Electronic Supplement to
‘Automated Classification of Near-Fault Acceleration Pulses Using Wavelet Packets’
by Zhiwang Chang, Flavia De Luca and Katsuichiro Goda.

The supplementary material includes two parts: a table (S1) and a string of plots (S2). 
The table is to list the information of all the components that are identified as having 
significant velocity pulses from the NGA-West2 database (accessed on August, 2016); while
the plots are to display the acceleration, velocity and the displacement time histories 
of the components as well as the time histories of the cumulative squared velocity (CSV)
for each component. All plots are made using the software of MATLAB (R2012a).

	PGV:	peak ground velocity;
	EVP: 	energy of the velocity pulse in relative sense;
	EAP: 	energy of the acceleration pulse in relative sense;
	Tp,1: 	pulse period by peak-point-method;
	Tp,2: 	pulse period by the pseudo-velocity-response-spectrum.
