Few hours ago a glacier flood started from Grímsvötnum. But it was only confirmed few moments ago. The flood noise can be seen on following SIL stations around Vatnajökull.
Grímsfjall (increased noise)
Kalafell (increased noise)
This glacier flood is expected to reach it’s peak in about 4 to 5 days. If this is a repeat of the year 2004 events a eruption should start in Grímsfjalli in about 1 to 4 days from now. But if that plays out exacly like the year 2004 eruption remains to be seen. GVP has the eruption history of Grímsfjall here.
This glacier flood starts on the exact day as it did in the year 2004.

According to the Icelandic news today geological scientists in Iceland are expecting a eruption and a glacier flood from Grímsvötnum at any time and without a any warning. But last week they did detect harmonic tremors on the SIL station that is on Grímsfjall volcano. It is not known if the harmonic tremors where created by water or by magma.
Currently the Grímsvötn lake is full and is ready to burst at any time without warning. Because of that scientists and Iceland Met Office have increased the monitoring of Grímsvötn and Grímsfjall volcano. It has been six years since the last eruption at Grímsfjall (2004) and it only where six years before that eruption (1998).
