Reykjanes (Reykjanes peninsula (SW Iceland)): The eruption continues at stable but at low-level values.
The lava spattering of molten pyroclasts continues from the spatter rampart system. Three dominant cinder cones continue to generate plastic lava fragments that have been building edifices and feed the lava flow towards the south.

GPS measurements indicate the ongoing swelling of the Svartsengi area. The seismic activity continues at low levels, indicating freely movement of magma through dikes without generating any seismic energy.
The degassing becomes more efficient with widening vents as the eruption goes on and affects the area of Grindavík, the Blue Lagoon and Höfn. Significant amounts of SO2 concentrations were measured in the areas last night (9000 micrograms/m3), but they significantly decreased to background values. A large pyrocumulonimbus cloud has formed over the eruption site. Vapor clouds characteristically develop above open lava flows and erupting vents from the condensation of rising hot air, creating so-called pyrocumulus clouds. When these convectively expanding clouds reach sufficient altitude and size, they transition into pyrocumulonimbus clouds.

...28 Mar:
The explosive eruption at the volcano continues.
Another powerful explosion occurred from the crater vent last night. At about 03:20 local time, a tall glowing dome-shaped column rose several hundreds of meters above the summit, producing incandescent lava bombs. The event is highly likely to be classified as a paroxysm.

The volcano observatory reported a seismic signal with a maximum amplitude of 20 mm and a duration of 98 seconds.
In order to mitigate the current risk, people are advised to avoid the area within a 4.5 km radius of the Verbeek Crater.


Atka (United States, Aleutian Islands): (28 Mar) The alert status for the volcano was raised to "yellow", as a minor, short-lived explosion took place from the volcanic system last night.
The eruption was detected at 19:38 local time by infrasound and seismic recordings, as well as by the Korovin webcam showing a dark plumefollowed by a short-lasting volcanic tremor. No ash emissions have been observed in satellite images.
