Eruption continues at stable levels, lava flows to north

The effusive eruption has been stable over the past week.
The lava continues to keep the flow active in the northern direction and gradually has been invading flat terrain near the Sýlingarfell mountain where the flow front has been thickening.
Lava beds are forming at the south of the main crater due to tha lava accumulation.
A small cone opening in the western crater rim appeared on 17 June at noon, triggering a small lava overflow to the west towards the Sundhnúkur mountain, but it seems to be inactive.
Despite the ongoing eruptinn, the Svartsengi reservoir continues to exhibit the ground uplift, similar to what was observed during the previous eruption. Geodetic modeling indicates that the inflation of the magma reservoir beneath Svartsengi is due to an additional volume increase of 1-2 m³/s. When the magma accumulation rate beneath Svartsengi is combined with the lava extrusion rate at the surface, it provides an estimate of the total magma inflow from depth. However, there remains considerable uncertainty in the model calculations and in the estimation of the lava extrusion rate from the past week, which can affect this assessment. The development of the unrest will continue to be closely monitored.
Between June 3 and June 10, the lava extrusion rate from the eruption was estimated at approximately 10 m³/s. Since then, there have been no significant changes in the eruption's activity, indicating that the flow rate remains stable.

The eruption continues at reduced levels.
The spattering is now limited to a cluster of about six eruptive vents within the fissure above which have been building the group of cinder cones, so-called spatter ramparts.
Tha lava flow along the Grindavíkurveg main road and protective barriers decreased its advance.
