A similar argument can be made using volcanoes, especially large volcanic eruptions such as Yellowstone and Toba; eruptions which supposedly occur every few hundred thousand years or so as it is, according to our "old Earth assumptions".
See the
comparison between Toba, Yellowstone, and Mt. St Helens found at

Creationism has always had an interesting relationship with impact cratering. Henry Morris once claimed that lunar craters were
made during the battle between Micheal and Satan, but I've never had one to attempt to use that explanation in a debate. It did make a good
cartoon, though.
I
have heard Creationists claim that "there are no buried craters", an argument that is demonstrably false because there are many
buried craters, such as Chicxulub, thought to be associated with the dinosaur extinction. There are other buried craters in less exotic places, such as
Virginia.
