The volcanic eruption that started in Geldingadalur, Fagradalsfjall mountain, on the Reykjanes peninsula, Southwest Iceland, shortly before 9:30 pm Iceland Time is still very small. It is the first eruption on the peninsula in nearly 800 years.
“This is just a small, effusive eruption,” Sigmundur states. “Lava is flowing slowly, but fissures in these kinds of eruptions are known to open and grow longer.”
The latest reports state that the fissure is now 700-meter long, located over the magma dyke that had formed.
