Seismic tremor: Magnitude similar to what it has been over the last few days.
Earthquakes: An earthquake of magnitude 1.4 occurred under NE-part of
Eyjafjallajökull this morning.
GPS deformation: Indicates very minor subsidence towards the center of the volcano.
Magma flow: No observations

and the groundwater module. The coupling
between both modules was done by a net boundary flux between the unsaturated zone and
the groundwater (Schulla & Jasper, 2007).

added to a classic degree-day model. For infiltration, a methodology of Peschke, based on
the approach of Green and Ampt, was used. To calculate the fluxes within the unsaturated
soil zone, the Richards equation was used. The groundwater table was modelled in both the
unsaturated zone module and the groundwater module. The coupling between both modules
was done by a net/media/ces/2010_017.pdf

decision and the factors are interlinked, all of which makes
the problem highly complex. The part of the net defined by
variables and links is relatively easily communicated to
stakeholders (Henriksen et al., 2007b). However the

covered. The central volcano, also called Katla, is located under the
Mýrdalsjökull ice-cap but its ice-thickness goes up to 700 m. The associated
fissure swarm reaches ~70 km NE towards Vatnajökull. The Katla volcanic system
is the fourth most active system in Iceland and has erupted at least 21 times
during the last 1100 years. During historical time, the average repose period

until now, the majority of seismic events have been calculated to be at 5-10 km depth. There is no
sign of upward migration. The event rate is still high. ~4000 events have been automatically
detected since the beginning of the swarm on Saturday morning, ~700 since midnight today.
Activity ebbs and flows in pulses of several hours lengths. The last pulse of high
