earthquake activity north of GrindavíkRecent data show
that uplift has started again, with the center just west of Mt. Thorbjorn.
Uplift was measured from 22. January 2020 until beginning of February and has
started up again during the first half of March. During the first sequence in
January-February, the deformation rate was about 3-4 mm per day with a total of
a 6 cm uplift during the whole

continues to be strong. Since Friday, 7. November, around 200 earthquakes have
been detected in the caldera. The biggest one was M5,2 yesterday at 21:19. In total 20 earthquakes between M4,0
and M5,0 were detected since Friday.
The subsidence of the Bardarbunga caldera continues with similar rate as last few weeks.
In total 20 smaller earthquakes were detected in the dyke and at the eruption site

returned back to green. Ground deformation indicates that magma continues to accumulate at depth since August 2021 and a total uplift of 40 cm is currently measured in the inner part of the caldera. This deformation is however not accompanied by elevated seismicity which continues to be within the known background level. This return to green is taken considering the need of the ACC to communicate
