at each site i with the same method used to estimate qR(D;T ), but instead of pooling
AMF series for a given duration D from different sites, the estimation is made individually for
each site i by pooling AMF series for different durations D (see Crochet, 2012c). The index
flood µi(D), is modeled at each site i as a continuous function of D, as follows:
µi(D) =

Figure 2. Discharge (m³/s) measurements at Gígjukvísl bridge: From the curve the total amount of floodwater is estimated 0.45 km³.
The discharge curve is typical for jökulhlaups from Grímsvötn that do not result from volcanic activity: Over the course of several days, the amount of water flowing through an ice tunnel at the glacier bed steadily increases. Loss

September the productivity of the eruption has decreased.
Seismic activity in Bardarbunga continues to be strong. The biggest earthquake that was detected since noon on
Wednesday, 18. November at 00:26 was of magnitude M4,6. In total 16 earthquakes bigger then M4,0 were
detected over the period and 39 earthquakes

There is a double pulse cycle, or fluctuation, one takes hours and the other
takes between 10 and 20 seconds.

The biggest earthquake that was detected since noon on
Wednesday, was of magnitude M5,1 this morning, 28. November at 06:41. Since noon on Wednesday 7 earthquakes
larger then M4,0 were detected in Bardarbunga and 12 earthquakes between M3,0-3,9. In total about 170
earthquakes were detected in Bardarbunga since Wednesday.
About 20 earthquakes were detected in the dyke and around the eruption

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
