Tongan volcano eruption leaves scientists with unanswered questions
Scientists scramble to understand the devastating Tongan volcano eruption, and modelling how societal changes might alter carbon emissions.
In this episode:
00:46 Understanding the Tongan eruption
On the 15th of January, a volcano in the South Pacific Ocean erupted, sending ash into the upper atmosphere, and unleashing a devastating tsunami that destroyed homes on Tonga\u2019s nearby islands. Now scientists are trying to work out exactly what happened during the eruption \u2014 and what it means for future volcanic risks.
