## Electronic Supplement to

A New Pulse Indicator for the Classification of Ground Motions

by Vassiliki Kardoutsou, Ioannis Taflampas, and Ioannis N. Psycharis

This electronic supplement contains Tables S1 and S2. In Table S1, the classification of the fault-normal components of 221 records from the Next Generation Attenuation-West2 Project (NGA-West2) database with peak ground velocity (PGV) > 30 cm/s is given according to Baker (2007) and the proposed methodology. Table S2 contains the proposed pulse indicator (PI) index for 91 records characterized as pulse-like by Baker (2007) calculated for (a) the Mavroeidis and Papageorgiou (2003; hereafter, M&P) wavelet and (b) the Daubechies wavelet.

### Tables

Table S1. Classification of considered records. Columns 1–5 correspond to fields in the NGA-West2 flatfile, columns 6 and 7 give the PI index according to (a) Baker (2007) and (b) proposed methodology, and columns 8 and 7 give the classification of records as pulse-like, non-pulse-like, or ambiguous, according to (a) Baker (2007) and (b) proposed methodology.

Table S2. Proposed PI index for the 91 records characterized as pulse-like by Baker (2007) calculated for (a) the M&P wavelet and (b) the Daubechies wavelet. Columns 1–5 correspond to fields in the NGA-West2 flatfile, and columns 6 and 7 give the PI index calculated for the M&P wavelet and the Daubechies wavelet. Values in bold show records that are classified as ambiguous by the proposed methodology. All other records are classified as pulse-like.
