Hi,

The Volcano terrain can't be destroyed by putting a building on it, however I'm afraid the only way how to find it is to check a terrain under each building again.

Also, I recommend to check Monkeys & Items &rarr; My Tracks where you can make sure that you really captured at least one Volcano square.
