Moi, Paul Derand

• Subsidence of the caldera floor and tremor along the caldera rim continue, suggesting a sub-glacial eruption can take place in the caldera. This "phreatomagmatic" eruption would lead to jokulhaups and ash producing activity.
• The eruption at Holuhraun continues although its rate decreased slightly. The lava field covers about 25 km².  Tremor continues in Holuhraun but remains weak, subsidence in this area is nearly insignificant. It seems that the dyke's activity would decrease  in the next few days.
• The eruption's SO2 cloud extends to E Iceland, where concentration of gases can be high. This cloud is expected to move N according to the Icelandic Met Office. These conditions can change suddenly as weather is changeable.
