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

Volcanic gas can still get dispersed all over the country, see a note from meteorologist on duty; emission of gases has not ended, neither from the inactive vents nor the extensive lava field. See how toxic values may actually get higher.
The lava field is 85 km². Its average thickness is 10 - 14 m (max 40 m) and its volume is 1.4 km³. The maximum subsidence

5.6 earthquake in the vicinity of Núpshíðarháls, which occurred at 13:43 on
20th October. The maps displayed here show ground deformation associated with
movement on faults during the period 16th-22nd October.The large signal shown
in the vicinity of Skolahraun represents movement of up to 5 cm

The current period of unrest began in July 2011, when a short-lived glacial flood burst from Mýrdalsjökull in connection with increased seismicity. Since then, several hundred micro-earthquakes have taken place within the area of the caldera. The enclosed graph shows how the ongoing activity compares to earlier episodes of seismic unrest at Katla in 1999 and 2002-2004.

Over the weekend there was a technical breakdown in data transmission from web-connected gas detectors in
east and north part of Iceland. The issue is being resolved.
A new online gas detector will be put up in Höfn in Hornarfjörður tomorrow, Tuesday

The GPS station in the centre of Bardarbunga show that the subsidence of the caldera continues with similar rate as
it has done over the last few weeks.
Smaller earthquakes are detected in the dyke and at the eruption site
