once upon a time that SoB got pelted!! Bigtime!! From every single direction!!! lol...
Lucky for Mimas it has a thin crust with an iron sphere underneath, just like our Moon. (Kidding)
NASA article on types of findings from the 1969-1972 seismographs placed on the Moon by astronauts....
The first three were generally mild and harmless. Shallow moonquakes on the other hand were doozies. Between 1972 and 1977, the Apollo seismic network saw twenty-eight of them; a few “registered up to 5.5 on the Richter scale,” says Neal. A magnitude 5 quake on Earth is energetic enough to move heavy furniture and crack plaster.
Furthermore, shallow moonquakes lasted a remarkably long time. Once they got going, all continued more than 10 minutes. “The moon was ringing like a bell,” Neal says.
On Earth, vibrations from quakes usually die away in only half a minute. The reason has to do with chemical weathering, Neal explains: “Water weakens stone, expanding the structure of different minerals. When energy propagates across such a compressible structure, it acts like a foam sponge—it deadens the vibrations.” Even the biggest earthquakes stop shaking in less than 2 minutes.

The moon, however, is dry, cool and mostly rigid, like a chunk of stone or iron. So moonquakes set it vibrating like a tuning fork. Even if a moonquake isn’t intense, “it just keeps going and going,” Neal says. And for a lunar habitat, that persistence could be more significant than a moonquake’s magnitude.

John Belushi, on seeing this photo only had one word to describe it, “ZITS”!
