It was the blast heard around the world - and it wasn't only those of us on land who would have heard it. Just over a week ago, the loudest volcanic eruption in more than 100 years blasted Tonga - creating a destructive Tsunami and producing a blast wave felt as far away as Europe. Marine Scientist and Principal at Canada's University of Victoria Matt Pine, has been studying the impacts of underwater noise on sensitive marine life. Nathan Rarere asked him if the underwater shockwave from the eruption, would have killed any nearby marine life.
