Distribution of impact craters generated by ballistic ejecta. Zone A: N ≥ 10 impact craters per 5 × 5 m, Zone B: 9 ≥ N ≥ 3, Zone C: 2 ≥ N > 0, Zone D: N = 0. The dotted line in the middle shows the long axis of the distribution of impact craters. The topographic base map was produced using a GSI map issued by the Geospatial Information Authority of Japan
