Extended Data Fig. 4: The maximum crater size erased by our modeled surface seismic wave as a function of distance.

The black solid line represents our nominal solution, and the blue shaded region shows the model’s 1-sigma uncertainties that is centered on the modeled curve. Craters with D < 250 m within the entire Shallow Crater Region are erased by the surface seismic wave alone. At the antipode, only craters with D < 10 m could have been erased by the surface seismic wave.
