„According to the study, the chance of a damaging moonquake occurring near an active fault on any given day is about 1 in 20 million.“
Sounds like they’re not very common. I wondered why I had never heard of these before

Yeah, a broken window on the moon would screw up someone’s day pretty good I bet.

This article does not go far enough IMHO. For a permanent base, risk is more than the probability of a „damaging moonquake“.
Between 1969 and 1977, Apollo missions measured 35,000 seismic events (12 per Earth day). Vast majority are shallow moonquakes due to moon’s crust cracking. Because moon is cooling, so it contracts.
That is a big challenge for a permanent base, it will have to resist those light, but frequent, moonquakes. Each one lasts several minutes.

Does any of this even matter anymore? This trash administration has pretty much rendered NASA useless. It’s disgraceful what’s going on.
