Interesting. As Shoemaker-Levy demonstrated, things like asteroids and comets can break up and make multiple impacts. Here is a chain 23 tiny craters in a string up on the moon
One is suspected to exist in the central U.S., stretching in a line 435 miles from eastern Kansas, across Missouri, and across the southern tip of Illinois. It consists of eight circular depressions, ranging from 1¾ to 10½ in diameter, with at least two confirmed as impact craters dating from roughly 300 mya.
And IIRC there might be some up in Canuckistan as well. In any case, these are pretty close together, unlike Kiev and the Yucatan Peninsula.
