Scientists mapping the after effects of Tonga’s underwater volcanic eruption that occurred in January, say there are signs the volcano is still active. The eruption which also triggered a tsunami, has been described as the biggest explosion ever recorded by modern equipment, with the effect being felt as far away as Alaska and even in the UK where scientists discovered the explosion had lifted the cloud base over the UK. Next month, a robot ship, the SEA-KIT Maxlimer  will be sent in to explore the inside of the volcano's crater.
