and satellites) confirm that the uplift, which commenced in the beginning of August at Askja volcano, is still ongoing. The total deformation (up component) has now reached 7 cm. As more data have been collected, the on-going process results to occur at high speed.
Deformation modelling results constrain the ongoing inflow of magma at a depth between 2 - 3.5 km (on average).

this morning gave 455 m3/s, and another measurement, around 16:00
GMT, showed an increase to 627 m3/s. Electrical conductivity has
increased since the beginning of the outburst from 180 µS/cm to 320
µS/cm.
Seismic tremor: Seismic tremor has been increasing at seismic station ‘grf’, located
near Grímsvötn, since late on 27 October 2010. This tremor is similar
in character to the tremor
