This situation is unclear and nothing has been confirmed as of writing of this article. This seems to have started about 1 hour ago and there has been a change in the harmonic tremor levels at Grímsfjall volcano. This is not yet the super sharp change I did see in May-2011 when that eruption happened. This is however is possibly a change in harmonic tremor that is consistent with magma moving inside the volcano system. Earthquake activity has been minimal in the last 24 hours.
This is a monitoring situation currently. Sometimes an eruption happens after a glacier flood or doing a glacier flood in Grímsfjall volcano. At other times however nothing happens and it is not possible to know what happens now.
