‘Lava Eggs’ Form by Active Volcano Near Reykjavik in Iceland

June 20, 2021

Unusual molten rock formations recently appeared near an active volcano in Iceland’s Reykjanes Peninsula. They were spotted by a geologist, who explained to Reuters how the egg-shaped lobes, known as pahoehoe lobes, formed. Matthew Thirlwall of Royal Holloway University of London said the structures, which form at the base of the lava flow, are fed “from inside the flow,” which  “breaks up these egg-shaped lobes and pushes them apart.”
