On the northern side a tephra wall rises 20 meters above the water. The ice walls at the southwestern corner of the crater are melting, i.e. at the site of the vent that was active 4 - 6 June. The rate of melting is assumed to be about one cubic meter per second.

Seismicity is similar to previous days:
- There is low activity in the dyke intrusion. Around 20 earthquakes have occurred during the last 24 hours, all within magnitude 1.5 and in the northern part of the intrusion between the eruption site and to the south some kilometers under Dyngjujökull glacier.
- About 80 earthquakes were detected on the caldera rim of Bárðarbunga. The largest earthquakes

1 Abstract
In order to investigate the effect of climate change on the hydrological regime in Iceland,
future projections of river discharge were made for two watersheds with the WaSiM

an important part of the runoff from many areas. In total, approximately
20% of runoff in Iceland originates from groundwater (Hjartarson, 1994a).
In the above mentioned previous simulation of runoff map for Iceland for the period 1961–
1990, groundwater was omitted. Effects of groundwater flowing across watershed
boundaries were simulated by scaling the precipitation for each watershed. On watersheds

earthquakes were observed in the dike intrusion and about 20 close to
Herðubreið.
The eruption can not be seen on the webcams.
