Reykjanes (Reykjanes peninsula (SW Iceland)): (6 Apr) Another significant change appeared at the eruption site over the past 48 hours.
As we mentioned in the last update, the northern cinder cone has been showing the most lava-effusion activity of two cones at that time. However, judging at least from the latest Sentinel-2 satellite acquisition from today, the larger, northern crater has become the one and only protagonist of the eruption. In the attached timelapse visualization (27 March-6 April), the southern edifice is no longer active, or it seems to have halted.
Fresh and molten pyroclasts have been continuing to eject from edifices, resulting from continuous spattering that thickens the lava flow field in their vicinity rather than its length, as seen in the attached timelapse.
