The string of volcanic eruptions in the Sundhnúksgígar area of Reykjanes could come to an end in July. Vulcanologist Haraldur Sigurðsson and Geophysisist Grímur Björnsson predict this as a likely outcome, Vísir reports.

Magma corridor narrowing

The first eruption in this series began on 18 December last year after a period of seismic activity, which triggered the evacuation of the town of Grindavík. Three more eruptions followed, with the most recent one lasting from 16 March through 9 May.

“The cooling and coagulation of magma in the magma corridor is constantly narrowing the magma’s path and will eventually end the activity under Sundhnúksgígar,” Haraldur wrote on his blog. “Based on the data, Grímur Björnsson and I predict that the series of eruptions will cease at the start of July.”

Next Reykjanes eruption uncertain

Haraldur added that the Department of Civil Protection and Emergency Management does not support their findings. “It’s a shame and, in fact, worrisome, that the Department has such a negative view of the science,” Haraldur wrote.

He added that the conclusion will be determined by how quickly the magma will cool down and coagulate. “The magma corridor will tighten and eventually stop all magma flow in Sundhnúksgígar,” Haraldur wrote. “But what happens next and where in Reykjanes it will happen is of course completely uncertain.”
