Quarter-wavelength representation of the velocity profiles. See Poggi et al. (2012). Characterizing the Vertical-to-Horizontal Ratio of Ground Motion at Soft-Sediment Sites. Bulletin of the Seismological Society of America, 102(6), 2741–2756.

Profile Picture
Z0.8 (m) 0.0

Z0.8 is the depth where the average of the profiles reach the velocity of 0.8 km/s

Z1 (m) 0.0

Z1 is the depth where the average of the profiles reach the velocity of 1 km/s,

Z1.5 (m) 8.0

Z1.5 is the depth where the average of the profiles reach the velocity of 1.5km/s
