Snapshots of the seismic wavefield for an impact cluster centered on longitude −125.759° and latitude −3.61615° (Site 11 in our database); synthetics are available in the online supplement. This impact cluster consists of >192 individual craters, with the largest crater having a diameter of 17.5 m. Using cluster geometry, we estimated an azimuth of 30.9° and impact angle of 55.3°. A) HiRISE image PSP_007036_1765 of the highlighted region. North is up. B) Vertical displacement snapshot situated on the cluster at the origin time of the simulation. Red box indicates the context for the image from part A. Each panel is a zoom on the central 5 km × 5 km region at the center of the 20 km × 20 km × 20 km simulation grid. Crater positions are marked in black. The time step of the simulation snapshot is indicated in the upper left. C-E) time steps into the simulation; ground displacement is scaled equally in all panels and is saturated on the color scale.
