I took a student vacation work job in a fish factory in the Westman islands to the south of Iceland just a few months after the appearence of Surtsey about 10 miles away. We could clearly see the irruptions. There are now trees growing on it.
A few years after I left, Heimey, the volcano on the Westman Islands, irrupted and destroyed a significant part of the port. We had taken a midyear midnight picnic in its crater. Just got out by the skin of our teeth - on a geological timescale!
