New ash trail on top of Eyjafjallajökull

The news tonight at Stöð 2 (Channel 2) in Iceland reports that there is a new ash trail visible from the top crater in Eyjafjallajökull. It can be seen because of the new snow layer on top of Eyjafjallajökull that did fall few days ago.

Geologists find this interesting. But they are unclear on why this happens. But they doubt this is due to explosions happening in the crater. The ash is either carried by steam or by wind over the crater rim and falls into the new snow on top of Eyjafjallajökull.

The news can be viewed here (in Icelandic, Windows Media Player required to view this video).

Deep earthquakes starting again under Eyjafjallajökull

Over the past weeks there have been deep earthquakes happening under Eyjafjallajökull. The deepest earthquake so far that has happened was on 21 km depth. The latest earthquake that happened was on close to 15 km depth. Currently it is impossible to know if there is new magma pushing up.

If it is, then the amount of magma that is rising up trough Eyjafjallajökull is not great and is unlikely to start a new eruption any time soon. It is however worth noticing that this might change with a short notice. But the eruption in March to May 2010 did show that magma can rise fast up trough Eyjafjallajökull and appears to be followed by earthquake activity.
