Eyjafjallajökull: The volcano that stopped a continent

In 2010, a previously little-known Icelandic volcano erupted twice, sending a huge plume of volcanic ash all over Europe. The ash cloud grounded flights for days, causing disruption for millions of passengers. Reena Stanton-Sharma talks to Icelandic geophysicist and Eyjafjallajökull-watcher, Sigrun Hreinsdottir. This programme was first broadcast in 2022. (Photo: The awesome power of Eyjafjallajökull. Credit: Getty Images)
