  1. “–” means that F p and fNL cannot be identified
  2. aThe V S30 data were taken from the NGA-West2 database (http://peer.berkeley.edu/ngawest2/databases/)
  3. bStations 51MXT and 62WIX are located at rock sites, and the other stations are located at alluvial sites based on station construction reports
