The period from the initial indication that an eruption was likely at Reykjanes Peninsula up to the time the magma broke through to the surface, tells a fascinating story about volcanic eruptions in Iceland—how a possible eruption is spotted and how the information is communicated to the public. One can also find out how an eruption typically begins in this small volcanic island and observe the deep fascination Icelanders have for eruptions like this one in Geldingadalir.

On the evening of March 19th, an eruption began on the Reykjanes Peninsula.  It was not a surprise as thousands of earthquakes had shaken that region for more than a year. An indication that an eruption could be expected.  As is common in Iceland, an eruption begins with a fissure on the surface, and glowing magma begins to float around the region. The fissure can extend for many kilometers, as it extended up to 27 kilometers in Skaftáreldar in 1783.
