On Monday 26-December-2016 (second day of Christmas) a magnitude 3,3 earthquake happened in Katla volcano. This was the largest earthquake that day. Following this earthquake a few dozen smaller earthquakes have been taking place, the last ones in the past few hours on 27-December-2016. The largest of those earthquakes had a magnitude of 1,6.

There has been some fluctuation in the conductivity of Múlakvísl for the last few days. Not all of it might be due to magma related matter getting into the glacier river (at least not new material). The bad weather is moving old volcano ash and sand and some of it is falling into the nearby glacier rivers and increasing conductivity. Along with old material melting off the glacier in the sudden heat that has been going on in Iceland for the past few hours.

Storm warning

Please be aware that if you are in Iceland that a storm is about to hit Iceland and it appears to be rather bad. It is going to start to get colder in the next few hours and start to snow again after the sudden heatwave that happened in Iceland for the last 24 hours. This means closed roads, impassible roads, heavy snow falling down and other problems that come with this type of weather. This storm is not expected to end until 29-December and then a new storm might happen. Good weather is not expected until 30-December-2016 or 31-December.
