Fig. 4: Comparison of the Martian impact rate as a cumulative SFD plot.
From: An estimate of the impact rate on Mars from statistics of very-high-frequency marsquakes
The left and right axes show the yearly rate per square kilometre and globally, respectively. The bottom and top axes show the crater diameter and corresponding MW. Shown are results from Teanby31 (model 2, black dash-dotted line with grey uncertainty band), Daubar et al.5 (brown circles with uncertainty bars), Hartmann and Daubar33 (blue dotted lines, primary (P) craters; dash-dotted lines, primary and secondary (P + fS) craters) and Hartmann3 (dark blue solid line). The Seismology Gutenberg–Richter-derived rate is given by the red dashed line. The red uncertainty was derived by standard error propagation techniques (see Supplementary Information Section 3 for more details). The Cratering results are given by the red diamonds. Error bars were computed as sqrt(N) for each bin, as listed in Supplementary Table 1. The best-fitting rate is the solid red line.
