Eruptions and Disruptions: A NR Special
Newsround's Ore has been to Iceland to investigate the volcano that's been causing chaos over the past few weeks.
Over six days, hundreds of flights were cancelled after a huge ash cloud drifted in and out of UK airspace. Some Britons are still stranded abroad.
Ore's been finding out what it's like for Icelandic kids growing up in the shadow of the volcano and whether there could be another massive eruption.
