Reykjanes (Reykjanes peninsula (SW Iceland)): 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.

…17 Mar:
The effusive eruption resumes.
Fissure vents continue to feed two lava arms flowing in the western and southeastern direction, respectively.

The westerly spilling lava travels across the Grindavíkurveg road by layering the previous lava flow from February. The southeastern lava branch continues to invade along the protective barricade with an estimated discharge rate of about 300 m/h.
The fountaining continues along the entire chain of eruptive vents, generating juvenile, molten lava clots and gradually has been constructing new spatter cones above vents.

…17 Mar:
A new hazard assessment map for Grindavík area has been published by the Icelandic Met Office due to the ongoing eruption.
The danger in the highest risk zones has increased significantly as the new eruption commenced.

…17 Mar:
A new effusive eruption commenced on the Reykjanes Peninsula at 20:23 local time.
A 2.9 km-long eruptive fissure opened between the Hagafell and Stóra Skógfell mountains. The eruption site location is very similar to that of the recent February eruption.

Impressive lava fountains began to shoot several dozens of meters following the eruption onset. Fountaining continues to pour incandescent and fluid lava from a cluster of vents, feeding a new lava flow in the west direction. A new lava arm branched off the main flow, heading south towards the protective barriers. Unfortunately, the lava is (highly likely) on the way to the Grindavík and might hit the town.
At about 22:10 local time, the lava lobe front was approx. 200 meters from the artificial barrier, located in the eastern part of the town of Grindavík. At 22:20 local time, the lava flow was about 700-800 meters away from the Grindavíkurvegur road.

Fernandina (Galápagos Islands, Ecuador): (17 Mar) The effusive eruption at the volcano continues.
According to the latest Sentinel-2 satellite image of the eruption, acquired on March 16th, a cluster of several vents feeds the lava, which continues to keep the flow active on the south-southwestern flank. The lava flow has increased in length, currently about 8.9 km and slowly travels towards the shoreline, about 3.4 km from the sea entry. Once the lava interacts with water, it does so explosively, forming abundant steam-gas emissions, so called laze (lava haze).

As the volcano is uninhabited, there is no threat to the population.
