The mountains start and the floor begins to shake under the feet.

Not looking at each other, they shook hands under the table.

The bridge shook under their feet rather more than it should.

They were thinking about this when suddenly the ground shook under them.

A moment after that the ground shook under their feet for a few seconds and then went still.

The whole structure shook under the sudden weight, but held.

I tried to smile at him, but my legs were shaking under me.

I could only feel the beat shaking the floor under my feet.

The ground shook under their feet, throwing them off balance.

He laughed with me, and his shoulder shook under my hand.
