Has there ever been any human witness (photo) of volcanic activity on our moon? Perhaps, like an erupting volcano?
Could a large eruption cause fragments to be hurled into space?

No. The Moon has been volcanically inactive for billions of years. There are reports of transient visual observations on the Moon, but these are attributed to things other than volcanism.

Well, on the Moon you could argue that space begins at the surface. But it seems unlikely that any sort of volcanism such as the Moon once supported could eject material at greater than escape velocity (2400 m/s), so anything that went up probably came back down eventually.
