Any other theories as to why the house may have been vibrating,
especially for hours?

With me, it's been excess caffeine intake. At first I think it's the
house vibrating, but then I realize it's the core muscles in my body.

Ran it past the family doc and he said it's a common occurrence.

Any caffeine that enters my body comes from chocolate or green tea. I
don't drink coffee or sodas (Pepsi, Coke, etc.). And on that day, I may
have had one green tea at breakfast, 16 hours before reaching home, but
no chocolate.
