Magma flowed into the dike beneath Grindavík at an unprecedented rate of 261,000 cubic feet per second before the volcano first erupted in Iceland's Reykjanes Peninsula, according to a new study.
The volcano erupted on Dec. 18, with a 2.5-mile fissure opening and sending lava spewing up to 100 feet into the air. The volcano erupted again on Jan 14., with two fissures opening on the outskirts of Grindavík. A third eruption occurred today , with a 2-mile-long fissure opening up near Mount Sundhnúkur to the north of Grindavík. The events are part of a millenia-long cycle that fuels eruptions.In a new study published Feb.
"It means that other factors were important in explaining the fast magma flow — namely the forces due to the prior stretching of the crust as well as a large fracture on the boundary on the magma domain," Sigmundsson said."The stretching forces contributed very significantly to the driving pressure for magma flow in the dike, causing the very fast flow."
