Geysers

Hot springs are common phenomena in Iceland, geysers much less so. One of nature’s truly dramatic spectacles an erupting geyser is a sight never forgotten. The word geyser originates from Geysir — a well known spouting hot spring in Haukadalur.

Geysers are fascinating but the physics behind their eruptions is rather complex. Step forward Amanda Lloyd, a Manchester University undergraduate, who on a recent field trip to Iceland neatly summarised the science in a presentation she gave to the rest of her group. We’re grateful to her for allowing us to reproduce it here.
