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. There is no indication that a major eruption is imminent, but we know that magma still flows into the crust, is stored for a time and then occasionally erupts in an eruption.
