#3059: Water Damage

XKCD comic, described below.
Transcript

[Ponytail stands to the left of Cueball. She is looking down at a meter of some sort in one hand, and is holding a clipboard in the other hand.]

Ponytail: The crust under your house shows signs of water damage. Is there a subduction zone nearby?

Cueball: Uh, I think there's one off the coast.

Ponytail: Oof. I was afraid of that.

[Closeup on Ponytail who is pointing to a diagram of subducting faults.]

Ponytail: Subducting hydrous minerals carry water down into the mantle, causing melting in the overlying crust. If you let this go, you'll have volcanoes everywhere.

[Cueball, with his hand to his chin, looks at the diagram. Ponytail, holding her equipment, is standing behind him.]

Cueball: Is there any solution?

Ponytail: Giant lithospheric dehumidifiers. But the installation won't be cheap.

Cueball: Oh no...
