The activity at the eruption site continues at reduced levels over the past few hours.
The constant spattering generates molten lava fragments and emissions of incandescent lava from three fissure vents only.
Simultaneously, the seismic activity decreased significantly overnight. This follows a very similar pattern in the seismic evolution in compare to previous three eruptions on the Reykjanes peninsula.

According to the latest investigation of the lava flow map, model calculations suggest that the southerly traveling lava flow field will advance along barriers northeast of Grindavik towards the sea. The western lava flow is estimated to pass north of the Svartsengi geothermal plant, which is also protected by artificial walls.
