The most likely location of an eruption on Reykjanes is now considered to be north of Grindavík and east of Svartsengi Power Station and the Blue Lagoon, according to experts. The likelihood of an eruption has, however, diminished overall. The construction of lava barriers to protect the power station is ahead of schedule and while an evacuation order remains in effect, regulations on entering Grindavík for residents and business operators have been relaxed.
It has been a time of upheaval for the town of Grindavík (pop. 3,600), which was evacuated on November 10 amid powerful seismic activity. Earthquakes and the formation of a magma dike under the town have opened crevasses and damaged roads, homes, and infrastructure in and around Grindavík. An eruption is still considered a possibility, though the likelihood of one has diminished.
Grindavík eruption less likely
One of the reasons Grindavík was evacuated was that experts could not rule out an eruption in the town itself. Now, the most likely location of an eruption is considered to be between Sýlingarfell and Hagafell mountains, northeast of Grindavík and east of Svartsengi Power Station and the Blue Lagoon.
Data indicates that magma is continuing to stream into the magma dike that stretches below Grindavík and northeast from the town. However, some experts have suggested that the magma in the dike is partly solidified, though it would take months for it to solidify fully. While an eruption is still possible, it is considered to be less likely than previously believed. The likelihood of an eruption within the town limits of Grindavík is also considered less and less likely to occur.
Lava barriers ahead of schedule
The construction of lava barriers, which began around two weeks ago, is ahead of schedule, the Director of the Civil Protection and Emergency Management Department told RÚV. The barriers are to surround Svartsengi Power Plant and the neighbouring Blue Lagoon, and are expected to take 30-40 days to complete.
While an evacuation order remains in effect for Grindavík, authorities have relaxed restrictions for the town’s residents and businesses, who are permitted to enter the town in order to take care of their property and retrieve belongings. Some businesses have also begun operating once more during daytime hours. While some of the town’s water and power infrastructure sustained damage in the recent earthquakes, water and power are functional in much of the town and repairs are being conducted.
Iceland’s Parliament passed a bill yesterday to provide financial support to businesses in Grindavík whose operations are impacted by the evacuation. The support is intended to help businesses continue to pay out employee salaries over the coming months.
