And the mountains of Korim shuddered and groaned and heaved as the sea swallowed them.

The mountain shuddered.

The mountain would shudder, and several tunnels would be crushed in.

Indeed, that seemed to be the case, because the mountain shuddered and blew out a plume of gas.

The mountains themselves will shudder, and the sky will cry for the death of that foolish boy Cadderly!

The whole mountain shuddered, blew up.

Surely mountains shuddered when they met.

Then the mountain shuddered.
