Fig. 3: Overview of confirmed impacts and VF events detected by InSight.

a, Seismic moment as a function of crater diameter. The coloured markers show the seismic moment measured at InSight and the observed crater sizes (circles for single craters and triangles for the effective diameter of crater clusters) for the six recently detected impacts listed in Extended Data Table 1 (refs. ^13,15). The vertical error bars reflect the uncertainty in seismic moment magnitude derived using standard error propagation techniques. The horizontal error bars are given by the resolution of HiRISE images used to determine the crater sizes. The black line shows the least-squares fit to these events and the associated uncertainty (shaded area). b, Detectability of craters of a given diameter as a function of distance. The filled black circles and triangles are the observed, but not seismically detected, impact craters and crater clusters (respectively) that were constrained to have occurred during the InSight mission. The coloured filled-in markers indicate the observed and seismically detected craters and clusters, colour-coded by event name, as in a. The hollow diamonds in corresponding colours are the predicted crater sizes of detected impact events based on seismic moment magnitude. The black hollow diamonds show the distribution of predicted crater sizes for all other VF events. The solid black lines indicate the detectability curve. For distances up to 45° (~2,600 km, marked by the vertical black line), this is defined by the amplitude–distance scaling relationship. This curve defines the area in the ATF used to scale impact rates. Data are presented as mean values ± standard error derived using standard error propagation from uncertainties associated with a seismic moment versus crater diameter relationship and the spectral fit of the VF events.
