satellite data reveal that Askja volcano began
inflating at the beginning of August 2021. The uplift signal is centered on the
western edge of Öskjuvatn, close to Ólafsgígar, and corresponds to ~5 cm/month
of vertical motion. Geodetic modelling (performed using both GPS and satellite
data) indicates that the source of this inflation is located at a depth of
approximately 3 km and corresponds

draining from Vatnajökull regions affected by the unrest is normal for this
time of the year. At the Upptyppingar hydrometric station on Jökulsá á Fjöllum, discharge has
averaged 180 m3/s in recent days and conductivity is close to 180 uS/cm. A sensor in
Rjúpnabrekkukvísl (Skjálfandafljót water divide, NW part of Bárðarbunga) shows 60 uS/cm today

Lightning
No eruption and no eruption cloud.
Noise
No eruption and no eruption cloud.
Meltwater
No eruption. Daily measurements of water samples from Upptyppingar on Jökulsá á Fjöllum have
shown a stable conductivity of 200 µS/cm since Sunday.
Conditions at eruption site
No eruption.
Seismic tremor
No sign of harmonic (volcanic) tremor detected.

depth is determined by placing
50 cm of snow water equivalent (SWE) (or 500 kg m 2 of snow) on top of the permanent snow
regions, as defined by the model glacier mask. The “snow on glaciers” runs are used for most of
the analysis presented here, whereas the “no snow” runs are used in the last section, to determine
the impact of glaciers on the thermodynamic properties of the boundary-layer
