The fjord at the end of there’s the Heimaey harbour, Vestmannaeyjar (the Islands of the West Men), Iceland.
On one side are visible the acient cliffs, on the other (where the picture was taken) the new land created by the 1973 eruption. The encroaching lava flow threatened to destroy the harbour that was the main source of livelihood for most of the town. However, townspeople constantly sprayed the lava with cold seawater, causing some of it to solidify and much to be diverted, thus saving the harbour from destruction.
The eruption enlarged the island by about 2.24 km².
