Each panel shows the different tests of peak ground velocity from Parameswaran et al., (2023). Panel (a) includes only the three GNSS stations that were either closely located or collocated with strong-motion sensors. Panel (b) includes their strong-motion counterparts in the three chosen station pairs. Panel (c) includes all operational GNSS stations less than about 700 kilometers from the epicenter. In panel (d), the GNSS stations from (a) have been swapped with the corresponding strong-motion sensor data in (b). Triangles denote the GNSS stations and squares are the co-located strong-motion sensors. Contour lines show peak ground velocity derived from the different methods. Credit: Parameswaran et al. (2023).
