Figure 6

Measured versus modeled celerity. The color of the large symbols denotes the measured celerity of the respective arrival. Symbols are scaled in size by the signal-to-noise ratio (SnR) of the seismo-acoustic signal. Small colored dots indicate the calculated surface bounce points and their respective celerity as obtained from the acoustic ray tracing. The map image was created using the Matplotlib Basemap toolkit version 1.0.7: https://matplotlib.org/basemap/ (last accessed August 2019).
