Jökulhlaups (glacier outburst floods) One of the local impacts of Eyjafjallajökull was flooding. Jökulhlaups are more common in Iceland than elsewhere in the world because of the interaction of volcanoes with glaciers.
The greatest jökulhlaups from the sub glacial Katla volcano are among the largest floods that humans have witnessed. At their maximum, the discharge may be larger than the average discharge of the River Amazon. Yet Icelanders have learned to avoid the outwash plains of the most frequent jökulhlaups. Viewing the video clips plus the images and diagrams in the presentation, how do you think the flooding from Eyjafjallajökull changed the landscape and impacted on the local farms?

What? When? Who? Why? How? Where?
What were the local effects of the Eyjafjallajökull eruption? As you identify each effect, classify it into human or physical using the Venn diagram. Circle positive effects and underline negative effects. An example has been done for you. The community all worked together to clear up the ash. Lots of tourists wanted to visit the first eruption.
Environment or people? Many farmers successfully cleared their farms with the help of volunteers.
