A volcanic system in southwest Iceland has erupted for the third time since December. Lava from the eruption engulfed a pipe and cut off hot water supplies to about 30,000 people on the Reykjanes Peninsula.

Repeated rumblings of activity over the past few months suggest that the magma is active underground. The Icelandic Meteorological Office has detected increased seismic activity in the area since October, which may have been a precursor to volcanic activity. While volcanic eruptions are common across Iceland, the recent activity occurred in a region that has been quiet for centuries.
