seen in the beginning of eruptions when the magma is breaking
its way up to the surface and when an eruption is ongoing. Volcanic tremor is
usually even stronger when there is an eruption beneath a glacier (i.e.
Grímsvötn), in those cases there is interaction between the magma and melted
ice which increases the explosive activity in the eruption.

Wind directions were mostly from the northeast but there were a few days of northerlies, easterlies and northwesterlies on the Greenland Strait

in the following locations: 80 nm WNW of Bjargtangar, 46 nm NW of Barði, 40 nm NW of Straumnes and 41 nm N of Kögur. No icebergs were to be seen near the ice edge.
On the Greenland Strait, northeasterly wind directions were dominant to begin with, and most of the month, but at the end of the month there were a few days with southwesterly wind
