WebFigure 1.1: Earth model and idealized zero-oﬀset (ZO) seismic section in time. Each trace is recorded by a geophone coincident with the source position; and the light (dark) colored amplitudes correspond to the particle velocity of the ground in the upward (downward) direction. The background image on the far right is an actual seismic section.
