> 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.

> 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.

The dryness of the Moon presents an interesting challenge to tunnel boring machines that I don't often see addressed.

Do moonquakes imply a hot core and shifting tectonic plates?

Definitely no tectonic plates. Yes, there's a hot core.


I wonder if there's a power generation opportunity there.

Quell quakes and generate electricity at the same time.

Are you thinking massively scaled up piezoelectrics?
