Most of the interior of the moon is made up of the lithosphere, which is about 620 miles (1,000 km) thick. I know that microlith striking the Moon is fairly common, to the point that EVA suits are built to compensate for it, but I was planning to have a "meteor shower" kind of deal, where a "rain" of small asteroids or particles hits a small area over a short period (ten minutes or so).
