The fissure which opened north of Grindavík this morning measures 900 meters long and lava flows mainly to the west according to information from the Icelandic Met Office.
A smaller fissure, 100 meters long, opened closer to the town of Grindavík, and is about 200 meters away from the neighborhood of Efrihópur. Lava flows from it in front of the town limits and has already caused serious damage there, with at least three houses burnt and one almost under the lava.
Runs on to southwest
The long fissure is mostly north of the defense walls that have been constructed. They are directed to the west by the lava flow and the lava has covered part of Grindavíkurvegur road and then to the southwest.
The magma flowing out of the fissures, lava flow rate and lava size will be better evaluated tomorrow.
It is not possible to rule out that more cracks will form
Along with the formation of the magma dike to the southwest this morning toward and probably beneath Grindavík, there was a large deformation of new fissures and older fissures at the eruption site which occurred on November 10.
When the magma channel was formed last night, deformation was extremely rapid. After the second fissure opened, deformation was significantly reduced and almost stopped, especially at Hagafell and its northernmost point. Deformation is still detected within Grindavík but is decreasing.
The deformation is considered to be a sign that magma pressure is stabilising. However, it is not possible to exclude more eruption fissures.
